Inquiring about the feasibility of collection (as a separate topic in the encyclopedia) to repair TFT-TV and TV + DVD (TIR-clamshell).
Explain the essence of the issue - often (read - almost always) on these TV - no patterns - is meant to "kitaeznye" TV entering the market. Range of defects - variety of methods ... solutions, repair and different ... I suggest (if needed) to gather in one place all of this, including the series - "repair with a tambourine ...

Example of the recent repairs:

1. TFT TV Samsung S-17F (17'') - Turn on, no lights or running lights are not steady. In the process of repairing it appears that the defective control circuit, inverter, assembled at the AZ494 - (Insufficient level of control voltage to the main board). Lamps were first tested separately at the working of the inverter 10''double lamp TV (this inverter - an entire section - on the controller TL5001 I quickly check all the lamps in such TV from 5''to 17''). Offset by filing a 10K resistor with a contact, "+12 V" card power inverter to control the brightness of the contact connector inverter steady running lights restored (when you turn the voltage on this pin has risen to 2V at fault - less than 1V). Have already met twice. Apparently broken (increased resistance) interlayer metallization transition in the PP in the chain from the processor to the keys, but without the scheme his "catch" - not really!

2. In the TV + DVD (TIR-COTS) application is complete sound in DVD, in TV mode - everything is OK. The reason is not reduced to the level of logical "0" voltage switch between TV-DVD-AV output on the switch 4052. Again - in the absence of schemes - Troubleshooting "crawling along the paths and continuity did not give details as propayka, washing, etc. Connect resistor 4.7 ohms with a B transistor control this conclusion, the switch 4052 on the ground level has a logical "0" in the acceptable norms and sound in DVD - restored.

I understand that it is "not our way" - but they are 100% solve the problem with this class of products ...
Who else do in such situations, is there any sense in continuing this topic?

You can simply "dump" methods (approaches) to repair and interesting cases of repair products of this class ...


Here is the abstract:

The majority of TV, especially "TIR-clamshells with DVD - sensitivity tuner -" no ", I have an outdoor antenna sometimes finds 2.3 channel, exceptions do happen, but rarely. Sensitivity tuner they artificially cut my throat in order to reduce interference from the reception of the internal transducers.

If the alteration in the Auto goes very quickly - "throw" in memory (often quite clean). In predtorge occurred closure tire tuner on the body with a similar manifestation of the problem.


In the absence of reception and suspected tuner - Council first propayat, particularly the findings of contours and rinse with acetone - often helps in these TV. I propaivayu usual galvanicheskirazvyazannym 40W soldering iron - and everything is OK, no more "not kill", and the conclusions are well-integrated ICs propaivat through braid silvered screen with flux - and the station or a hair dryer does not need - and all so - OK! If there is a "fat flux" (similar to soap - even in the "scoop" released) - helps a lot - he is not active, but perfectly propaivaet conclusions contours. Then wash with a brush (I have my brush with a diameter of 1 cm), the tuner - inclined to pay to keep - samotokom all "dirt" and flux residues "kitaez" gone, then must thoroughly purged with rubber pear - enema. If after flushing appeared whitish coating on PP - this is not an obstacle, you can then rinse with alcohol, in addition!
Tuner is not normally fed to and propaivayu directly in the scheme. There are versions of printed circuit boards, which hit the back side of the tuner - is problematic - there is really only desoldering or gently turn down the tuner, but most of all - the tuner is soldered to the PCB, and this body passed beyond the board and fixed metal bracket - such propaivayutsya without problems, but not "... just by installing add-on components ..." - but also by the installation!

Faced today with amusing malfunction ... Did brow LCD + DVD in one bottle brands BBK LD1006SI after feeding on it Vault 24 instead of 12 after replacing the four pregnant litas boot disk driver (on the rare little burnt out for the occasion), the unit was sent to the client to test in our hospital. The next day, resort and grit - everything works, but the drive does not suck. Well, I think, again, the driver flew! Throw on the power supply - all Parkhaev! Grew it - sometimes, even you yourself messed up. He Sorry, the device under your arm and go. After an hour or so back at me - I can not do anything, says he. Well I have a box back to the table - all good! Take the tester and to his cabin. Napruga normal and the device in Bounce! Grit and staff from the feeder takayazhe Mui Ne. Well I have one feeder in ahapku with the device and on the table. In short, the whole shnyaga was burnt on 33 ohm resistors in the parallels (near the glass) zener diode with the reverse side meynplaty! My PSU (relatively nehily conventional CD / DVD player / recorder) at idle giving out 11 volts under a load of this devaysa sags right up 9voltey and it is on this napruge otchegoto he was comfortable! If not for this fact - mudohatsya I do with this devaysom to usrachki and mudohalsya be exactly the DVD part of the load line, since everything else worked on Hurray! Schemes of this Chinese never naschel and therefore can not be specified on the item numbers of those rezyukov, as well as I can not analyze the essence problemma. Nevertheless, I want to warn colleagues about such a rake, so do not fall into neponyatku

Portable TV-DVD Super 950D etc.
Defect: not running a local keyboard, there is no reaction from the panel.
The reason for these troubles in the aggregate holds open line coming from the DVD to the TV controller. Usually eager to bend in the pipe.
At present reaction to the panel, but no reaction to the local keypad, you must seek the cause in the SC6121-001 and its piping, as Local keyboard made a sort of stationary remoutom whose IR LED is directed to a photodetector. Again the train!
Information is provided Scorpion.

7''TFT LCD COLOR TV "SUPER" (without model)

Ingredients:
UOC: MST726A-LF
B3MD032999G
0716F

EEPROM - 24C16AN
ZQ1 - 12MHz
Tuner: TDQ-3EV8 (BG/1R1/B / / 712)
TDA9886T
ZQ2 - 4MHz
Sound - TDA7496

Predtorg came with a defect is not included. When connected to the +12 V LED POWER could light up red, or do not burn. By pressing a button POWER - No reaction.
Local keyboard, PC, tires - in order, closures, etc. no. On quartz ZQ1 (12MHz) generation is not. When podkidke obviously working quartz - TV earned. Cost to install seat native cavity - "Silence", although desoldering it from the back of the PP - all OK. The reason is quite interesting: the metal casing of the resonator prihvatyvaetsya drop of solder to the mass of TV. Cost to do this operation and the generation of frustrated! Closure (parasitic drain "- the kind of - not sorted out) - in the case. Enough to replace the resonator or to lift it above the PP and not freeze building on the lot - on the reception quality (presence of noise), visual - no effect. For reference - when you click POWER and turn on the TV LED should light up green, and only 4 seconds after the display lights and will be displayed. Mandatory additional propayka processor and flushing the PP, as quality of installation is very bad.

Another "Chinese"
1 - Proud inscription on the "board" - SONY.
2 - composition: a photo
3 - The failure of - the smell of burning at work.
4 - In the recent years have increasingly come to the repair of Chinese counterfeits of well-known brands. Example - a few devices such as "SONY". Unmarked - no. The Matrix 37 "- NONAME. Defect - in the trash "burnt choke chain stabilization and filtering the voltage at +12 V power supply inverters. In my case, PSU - 2. - One for power SSB, the second - for power inverters. I must say that vysheukazany power source inverters made in spite of all the rules and canons, choke after the rectifier diodes heated scary, until melting the plastic rear cover, charring the printed circuit board, and swelling of electrolytic capacitors. After analyzing the circuit design and measurement modes of supply, it was decided to produce a new reactor, with a more acceptable parameters. Were based on studies in the same subject Forum participants: Maxim Z and andros. As the core were to use 2 throttle group stabilization of kompovyh PSU ATX put together. Conductor cross-section was chosen experimentally, but the best was from 1 mm to 1,6 mm. The number of turns, after all experiments remained the same - 2 turns per volt. In my case it was 24 turns on the 2, put together, the rings. After modifications the throttle, the replacement of electrolytes are more resistant to heat (105 degrees), the device has been tested on a continuous run for 18 hours. Temperature of 75-80 degrees throttle, voltage inverters +12 V - stable, visually - the picture is normal. Further reduce heating reactor failed, too many "devour" inverters (up to 7A), and the circuitry of the source is poor. The alternative - instead of installing another full-time UPS, with the following parameters: U = +12 V, I = at least 10A capacity of at least 120Vatt.

Would like to express my personal gratitude Party andros for help in solving the problem.

Mini LCD-TV Subini S-6881T
The following information Participants Stelt and genam, For what they Respect and uvazhuha .... [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]

Title Subini S-6881T.Shassi JV-805F-A02.YA understand that this is the same as Super SP-805C, well, or like ..

General problem in the next-on-board inverter no parts, namely, Q3, Q4, Q5 and R11 By Q3 burnt podlozhka.kto know tell me that it stood! The unit turns on, but no illumination of the matrix, respectively.
Inverter board number JV-805C-20HV02, composition-mikr.T5001, trans T-1926.

Placed in such a combination Q3-2SB1204 (IRFU9024 have not yet reached), Q4-Q5-2SC4672.
The unit starts up, runs, but terribly heated (as much smoke starts after some time (prim.1min) Q3-2SB1204.
Lit on nutrition in the chain of emitter C6 47mkf/35v replaced.
voltage tranzyuke
E-11, 5c, B-11.1, K-CHV for inclusion in 3.7, and immediately starts to grow, Gaugeable to 5.7 volts, then cut out, as smoke tranzyuk nachinaet.No believe that it would continue to grow until tranzyuk not pierced by.Na base and emmitore voltage neizmeny.Trans durit?

The problem turned out to Chimay to T5001.
Replaced, it works does not get hot.
To check the charge was supplied by laborotornogo BP, when applying 12 volts, the current consumption of 480mA
Modes of transistor B-14, 2c, E-12c, K-CHV 5,7 v.Eto with intact T5001.
With a failure - modes of the transistor - see above, current consumption increases almost Luo 1,5 A - and then turns off to the transistor could not sleep.
Spread ostsilogrammy with faulty and in good Chimay, and who can come in handy.
On the top photos form with intact Chimay - rectangular pulses.
At the bottom - with a failure - seeing a parabola.

I thought I thought, and decided to write. The idea is that sometimes it is very difficult to find a replacement lamp failure. I bend my way. Is made equivalent to the lamp. (Figure 1) then strengthened to a two-sided tape (Figure 2), and then the same tape strengthened from above. (Figure 3). As an equivalent applied resistor 2 Tues
1.1 meg. Specifically - the device VVK 22. "Did not work one upper tube. After the work done TV work, with almost no loss of brightness. Maybe someone thread and useful!

Tuner: QSD-MT-T66

The unit includes all the features work, no reaction to buttons «Vol +» and «Vol-» (no volume in any of the regimes, there is no natural and OSD in this mode), but when working in the menu - they work just fine.
After you install a clean (FF) TV memory is included in 15-20 seconds (after initialization), there is a "second video input, which is not in TV [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة] And normally adjust the volume, but - in the auto search is finding stations only in the first and second bands, UHF - no (restructuring goes on, but not a single station - it is not).
Working firmware was obtained by manually copying the "Ponke" in the "battered" (written off the TV at fault) to 5 line, which is taken from the EEPROM after the self-initialization. TV will function normally.

Log in to the meter: holding the TV button «Menu» to include it (the adapter) into a network - within 5-7 seconds. unit will enter into service mode. Working in S / M buttons «Menu», «Vol +», «Vol-», «CH +", "CH".
The menu has the following sections:

White Balance
Function
Input Select
Option
Logo
EEPROM

In section Function is select the type of tuner (XUGUANG121 - in my case).

Little about TV + DVD to TW8806 - here:


unit came in for repair without any signs of life, only naprugi all were normal. After replacing the memory 24S16 - the phone came alive, but the image is flipped up-legs. " Ingredients: LCD part of SC8955, TW8806, 24C16. DVD compiled by Sunplus SPHE8281D.
From the menu, neither of which is not found. Maybe on the remote there is a button or something?. Somewhere in the conference slipped "inverted" image, but found none. Tell me pliz

In the menu or anything not found
That means bad looking
No such item in the menu or in the menu LCD, any SETUP DVD side.

Memory clean staged?

It was this ability (through the setup switch).

And the buttons on the remote Try clicking

no remote

What used to silence

Soldered back home memory. Though he had with her and half-dead - will not turn on DVD, turns itself off, does not catch feeds, but in the setup menu of channels do have a point rotate the image, and it works. Put again a new clean memory - an image upside down, but it works, but in the place where the old memory was the image rotation menu, now there point switching system sound.

a little tinkering with the new memory Partner code just a couple of menu items, including a turn.

Then look for the firmware or remote

Firmware is needed or not ask and bring the device similar to yours.

certainly needed, there client brought the console. Here's something I can not find somewhere saw the entrances to different service Chinese miracle, but I can not find. Poke pliz.
Oh yes, and on-board LCD parts written SP-108F - as to mine some of the models of Chinese firms SUPER indicated.

In the remote button on the Changeling!

DimonR, in the remote button on the Changeling!

brought this miracle of technology and switching only through menyu.Proshivku will try today to send

Firmware. Composition of LSD on the other. Break??

Firmware did not fit, but the entrance to the service helped. Thank you. The service has a point "Turn", activate it in the custom menu is added to rotate the image. Log-in service:
holding the Menu button on the machine, turn on him.

I can not kerf is the problem, I suspect the firmware curve, but it is only suspicion. Can infa on this gland who have. In an Internet nothing concrete has been found.

Was recently Chinese SONY DVD-318 SUNPLUS SPHE8200A,
SPHE6300A, PT6312BL on morde.No flash DIP 32 EN29F040A-70
sticker on her 318-hd62. Firmware leaked, sending if fit
but with AT24C02 not have the time machine zabrali.Neispravnost:
hung up after a few minutes play, very
basked driver CD5954, replaced it all OK.
There are several Chinese SONY DVD-8068A based SUNPLUS SPHE8202A FLASH DIP 32 SST39VF040-70-4C, SC6961 on the face.
Those with MPEG4 but no picture, only sound on recordings
with Divx 3 and 4. Can someone something like that share firmware.
AT24C02 becoming a net and without it the result is the same.

File with the circuits on this marvel posted in the exchanger.
Himself has not yet figured out. Disastrous not enough time

Sitronics DV-1045 with SUNPLUS SPHE8200A, SPHE6300A, flash DIP 32 EN29F040A-70, EEPROM

No playback DIVX, MPEG-4.Prekrasno works, but when pressing the buttons on the front panel does not respond to remote knopki.S all switches properly. There is a suspicion of confusion in the wires to the connector CN-4.Ni whom such a defect is not caught? From the scheme would also not given.
The factory operating software from Flash and EEPROM - is.

I have such trouble was, the reason turned out to be banal - the control board is cracked.

DVD elenberg with this chip. How do I connect??

While I do not know. In my devices on this chip flash drive is on the socket. So it is necessary tinkering programmer for flash

I, too, on the panels. Connector-ie, a MTool sees fleshkunado some prog dig.
I will dig.

About how you jack rechesh? pro - cpu3/cpu2/cpu-1/dvcc/game-clk/....i etc.? If you about it, then this is for joystick game.

I hasten to you razacharavat, this is exactly v sync & h sync and nothing more. at least in my board.
On the procedure (scheme) of the conclusions tx & rx not found.

what is it exactly v sync & h sync I understood, but perhaps as a percent of a switch?
Why the scheme signed by a second value tx & rx?
And if MTool connect, it works out a message that the flash does not determine the exact type was not recognized.
Further prog tries to read ............... but can not.

MTC-TOOL program only works with chips MEDIATEK MT-1369, 1379, 1389 and its data-cable (by the way is an analog three-wire data cable F-BUS NOKIA 3310) - make sure it is very simple: take any working factory firmware (software) from FLASH MEMORY player such as Sony, or like your player, with an extension BIN and it must load into the program MTK-REMARKER - as a result of the program will display a window with the answer that the software is not designed for vehicles to processors MT-1369, 1379.1389. Everything.

Enrolled in the repair of another Sitronics DV-1045 with SUNPLUS SPHE8200A, SPHE6300A, flash DIP 32 EN29F040A-70, EEPROM 24C02. Defect - not reading discs. The reason turned out to be banal, like FLASH removed from the crib, do not feel like sitting tight. Took out the legs cleaned with a scalpel, tucked back in a crib stronger - and it worked.

Yes, it balyachka known to me - the oxidation of the findings ms, standing on the panels. I have another. Flash tripped, the problem remains.

Colleagues interested in information about the players on the basis of SUNPLUS SPHE8200A, who read mpeg4, need to dump this machine, the entrance to the viewing disk imaging utility, if any.
Is there any possibility to activate the device without mpeg4 this feature.
Here's an example

In June of 2005 I purchased an S&V model 999 DVD Player from Foodtown (a large supermarket chain here in New Zealand). The instruction manual was a bit skimpy and so I've put together this page to help other owners. Note: The information on this page is for the S&V 999 DVD Player. Since I purchased my player I have seen newer S&V models being sold (i.e. a portable model and model S&V 4313 with a built-in card reader and USB port). I have received many queries from people about these newer models but I have been unable to help as I know nothing about these other models! The information on this page may or may not work for them; I can't give advice about these other models.

Manual: The manual is 30 pages long and covers setting up the player, using the remote, basic operations and trouble shooting. No mention is made about the JPEG picture functions, MP3's, Karaoke, etc. Hopefully this page will give you more info about these functions. Manufacturer: Until I purchased this DVD player I had never heard of S&V. Along with this DVD player Foodtown were also selling S&V TV's and mini-stereo's. Searching the Internet didn't reveal anything about S&V (other than it's a widely used abbreviation for Sound & Vision Magazine). Support for the S&V 999 DVD Player is provided by Yale Appliance Group Pty Ltd, who are an Australian company. Their support phone numbers are:
Australia: 1800 111 727
New Zealand: 0800 111 727
Mon - Fri 9:00AM - 5:00PM Australian EST
The Yale Appliance Group website says: "Yale Appliance Group represents leading international brands, however we are also Australia's premier supplier of Private Labeled products with the ability to source, brand and supply an extensive range of electronic products and whitegoods." From this I gather that "S&V" is just a brand name and Yale Appliance Group have just re-branded generic no-name products. I gather that this is quite common with electronic appliances. Internal Info: Opening up the DVD player reveals a Sunplus SPHE8200A and SPHE6300A chipset combination on the motherboard. Also included are a pair of Samsung K4S161622H-UC60 16M bit SDRAM chips and an EON EN29F040A-70PC 4M bit (512K x 8-bit) EEPROM flash memory. Unfortunately I can find very little information about this Sunplus chipset as it does not seem to be as widely used as the ESS and Mediatek chipsets. Here are a few sites with some info:

  • Sunplus-based DVD players have built in games? See link #1, link #2, link #3
  • Inspection of a Daewoo DVD player that uses the Sunplus SPHE8200A
Region Unlock: The S&V999 DVD player has a Region 4 logo on the back of it and the manual says "Regional codes are printed on the rear panel of the DVD Player, only DVD disc with same code can be played". After some hunting on the Internet I found that there is a standard Sunplus unlock code which works for this player:
[ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]

  1. Power on the DVD player.
  2. Open the tray.
  3. Key in 9735 on the remote.
  4. A secret menu should appear which lets you change the region as well as showing you the firmware revision and other settings.
  5. Close the tray to exit the menu.
The "9735" code also works without having to open the tray, but there must be no disc in the player for it to work. I found that my DVD player was already set to Region 0, which should allow playback from all regions. I've been advised that the above region unlock information also works on the following S&V models: 4313, 228, 1005, 3270. S&V Portable DVD Model S&V 12627: The following region unlock instructions were sent to me for the S&V 12627 Portable:

  1. Open Top Load Tray and enter 81328
  2. It will show CURRENT REGION (Normally 4)
  3. If you change that to Region 9 and close the top load tray, you then have a multi zoned player
S&V 999c Model: A couple of people have reported to me that the above region unlock trick doesn't work on the S&V 999c model. The secret menu appears but it's impossible to access the "Region" option. I don't know how to get around this problem for this model. S&V Portable DVD Model S&V 19262: I've had a report that the above region unlock trick doesn't work on the S&V 19262 model. S&V 301415 Model: I've had a report that the above region unlock trick doesn't work on the S&V 301415 model. Keying 5168 while having the tray open will access an information screen but you can't access the "Region" settings.
Setup: The manual makes a reasonable job of explaining how to plug everything in and how to use the Setup menu (see picture to the right). If you have any questions about what any of the setup options are about (i.e. aspect ratios, etc) then you will find the DVD FAQ will help you out. My unit worked straight out of the box with just a simple TV hookup (no home theatre or anything complicated). [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]
VCD and SVCD Playback Control (PBC): Both VCD 2.0 (Video Compact Disc) and SVCD 1.0 (Super Video Compact Disc) have a facility known as "Playback Control" (PBC). This allows VCD and SVCD discs to offer interactive menus and the user may control the playback, a bit like interactive DVD menus but the only keys allowed are Next, Previous, Default (usually the Play button), Return (usually the Stop button) and the numeric keys. The S&V 999 player disables PBC when a VCD or SVCD disc is inserted. Thus any menu is ignored and the video on the disc is started automatically. To enable PBC you should press the PBC key on the remote before you insert the disc. This is a rather annoying "feature". JPEG, MP3 and MPEG Playback: The specifications mention JPEG and MP3 playback, but the manual makes no mention of this. After some experimentation I have discovered that you can insert a CD or DVD (I can confirm that CD-R, CD-RW, DVD-R, DVD+RW all work ok) that contains JPEG pics, MP3 audio files or MPEG video files. The player will then build a list of all the files on the disc and present you with a simple file viewer.
[ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة] The picture to the left shows the file listing with folders on the left and files on the right. You move around this display by using the arrow keys on the remote: left and right to take the highlight between the different sections, up and down to move within a section. The inserted disc may contain a collection of JPEG's, MP3's and MPEG files but the file viewer will only show one file type at a time. The current file type is selectable by using the three buttons at the bottom of the screen (from left to right: MP3 audio, JPEG pictures, MPEG videos). You can change the file type being viewed by pressing the right or left arrow buttons on the remote until the highlight appears over the type that you want to change to, then press Enter. To play an MP3 file use the left/right arrow keys on the remote to move the highlight to the right-hand file listing, use the up/ down arrow keys to select the file you want to play, then press ENTER.
Other keys to use while in MP3 mode:

  • PLAY / PAUSE - Play or pause the file.
  • RAN - Randomly select which MP3 to play.
  • Left / Right - Increase or decrease echo.
  • Prev / Next - Skip to previous / next file.
  • Rev / Fwd - Fast reverse or forward through the file.
  • REPEAT - Toggle between repeating one, directory, all, off.
  • A-B - Set the start and end point for repeating a section of the file, press again to cancel.
  • OSD - Turn on the On-Screen Display which shows you the track number, mute status, repeat setting, playing time. Pressing again will change from showing the playing time to showing the time remaining. Pressing again will remove the OSD.
  • MUTE / VOLUME +/- - Change the volume.
  • 3D - Show and change the surround sound, equaliser, band, key settings.
  • PROG - When pressed while on the file listing you can select up to 16 files which will be played in the sequence you entered (see page 25 of the manual).
The picture to the right shows the file listing when it is set to view JPEG's. Note that files that are in the root directory will appear in the folder called "-", also folders and files are numbered. A note about filenames: Files with long filenames can be displayed / played, but the filenames are truncated for display purposes and spaces are changed to underscores. The player only recognises 3 character file extensions, so JPEG files should have ".jpg" extensions and not ".jpeg". As usual use the left/right arrow keys to move to the file listing and then the up and down keys to select a file to view. A thumbnail of the currently selected JPEG file will appear in the left-hand window. Press ENTER to view the image full screen. [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]
Other keys to use while in JPEG mode:

  • MENU - View several help screens that tell you what keys to use while in JPEG viewing mode.
  • Left / Right - Rotate the image clockwise / anti-clockwise.
  • Up - Flip the image vertically.
  • Down - Flip the image horizontally.
  • RETURN - Switch from full screen mode back to file list / thumbnail mode.
  • ZOOM - Zoom in and out. While zoomed in you can use the arrow keys to scroll around the image.
  • REPEAT - Toggle between repeating one, directory, all, off.
  • Prev / Next - Go to the previous / next image.
  • Play / Pause - Start a slide show of all the images. Press again to pause.
  • REPEAT - Toggle between repeating one, directory, all, off.
  • RAN - Randomly select which image to display when viewing a slide show.
  • OSD - Turn on the On-Screen Display which shows you the track number, mute status, repeat setting, playing time. Pressing again will change from showing the playing time to showing the time remaining. Pressing again will remove the OSD.
  • PROG - When pressed while viewing an image it cycles through all the transition options (i.e. wipes, extends, compress, windows, etc). When pressed while on the file listing you can select up to 16 images which will be displayed in the sequence you entered (see page 25 of the manual).
  • PBC - When pressed while on the file listing you will get a display of 6 thumbnails along with their filenames and sizes. Use the arrow keys to move around, ENTER to view the selected image.
MPEG mode lets you play MPEG-1 or MPEG-2 files. This means you can view MPEG files that you've created yourself or downloaded from the Internet without having to author a proper DVD. Use the file listing to select which MPEG file to view (note that the file extension must be ".mpg" as ".mpeg" will not work) and press ENTER to start watching it. While you're watching you can use most of the normal DVD playback keys (reverse, forward, slow, zoom, etc). Note that you can only watch MPEG-1 and MPEG-2 encoded video files; AVI, WMA, RM, ASF, etc won't work.
[ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة] Bugs! Unfortunately it looks like the firmware has some bugs in it. While I was creating this page I was doing lots of experiments with switching between the different JPEG viewing modes, and at one stage I managed to create the display on the left. It looks like the DVD player wasn't sure which mode I was in. Pressing the arrow keys made different coloured boxes appear.

well look like the update files from the disk for these devices.
With the ITC did boschego. Who knows the purpose of each file?

[ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]

SPHE8200A in theory should not support MPEG4, with support for MPEG4 are percent SPHE8202A.

How dare question with an overload device while viewing DVD? Got this the same machine on SPHE8200A, reads then 10 then 60 minutes - and RESET.

What is not understood - "overload" where and on what setting?

"Overload" vsmysle restart, the phone works but after some time resets and then again - just like in the first message Dedushkaand this topic.

When you turn on the LED in red, there is no reaction on the button ON / OFF.
The reason - "Gathering» EEPROM 24LC32A1. Working firmware in the clip.

Quickly verify this by doing the following - unsolder 5.8 conclusions EEPROM («raise" one side) and in 10-15 seconds after connecting an external adapter, press ON / OFF button on the TV. If the LED turns green, turn on lights and will "blue screen" - it means everything is OK, just "alter" the memory.
The case in this TV is not unique.


Posted 11/27/2009 - A similar kit (see photo priveshennye) - Diagonal 24 "model 24W4D, the fault is similar to that described above.
First LED orange after 10-15 seconds (sealed EEPROM - the imaginary "initialization") - is red, and then - in the translation in the RR - green.
Similarly, because of the EEPROM can be switched on TV from 3-5 times, or when, after the orange glow of the LED just goes out.

LCD TV Toshiba 15V300PR chassis Vestel 17MB21-1 .
No settings on the channels.
At no tuner 33B. The tracks led to the board power supply. There is converter from 12 to 33 on the transistor BC337-25 Pos. № Q801 . Transistor is in full swing. Continuity tester for transistors and harnesses do not give - all with a view correctly ... well, except that the SMD resistor R821 10th with little tan, but the call normally. Costs in the supply circuit of the converter.
Well, that stood beside a TV.
Tractor began to rearrange SMD ceramics - the last six capacitor C833 33n raspolovinilsya - with the crack was. Change the picture is the same. Can podpalenny resistor .. no further L806 ... No, L802 ... YES. Stands in series with R821 Nutrition. The resistance of 5 ohms, and serviceable has 28 ohms, that is Korotyshev in the turns, looks normal - not podpalenny.
Culprit was most likely C833 - Because it did not work in the converter mode, and eventually fried the food chain.

OPERA OP-VC148BA 17 "TFT LCD COLOR ATV / CARD READER / MONITOR

Ingredients:

RTD2660
CS7123
74HC4052D
VLF - SA7496LS
Tuner - XF TDQ-6CL (P/S/1R1/811)
DC / DC - TD1410C
416-26L1

When you run the auto scan tuning dial moves slowly (as it should), but no one channel is not found. Voltage at Pin 3 and 13 tuner is 0,9 V, instead of 5 volts. The reason for the installation of fixed bridge with a +5 V power supply circuit for the tuner (see photo).
