With exactly the same nonsense staknulsya to Samsung.
The reason - loss of winding TDKS that nurtures human resources.

break winding TDKS which feeds personnel - And then the IC CD

And modes in more detail? That the oscilloscope?

Diode AHOC not break?

Or emkostina there!

There is nothing more I can not say it before the closing was brought, all that had laid out, oscillating nothing until pacing. I remember another 1 leg voltage was 0.44v and 0.66v at 7.

The capacity of green in the frame (0,1 ICF)

Yes, there are already unsubscribed, is there a tricky personnel capacity
And when the diode voltodobavki I have a case, although the call normally.



Here I am. Capacity of thatcontact, it is normal and the face value of its 0.47 micron. So I start lookingoscillator signals at the input and output circuits, the signals of normal sizeand regular shape, but with a handicap. Food + and - 13c. is, took it for aprobe ostsila 13. at the anode vd401 okay chisty signal, analog cathodeheromantiya what that strong interference. The problem turned out tomicrocracks contact area visually, even through a magnifying glass can not seeanything. It seems to me that the crack has worked as a gap because the foodcame to mikruhi. A device svezhak no it has not climbed, with at leastpoyalnikom. So feel free closed. Thanks to everyone who was not indifferent tome!

The image is stretched and the sides of "cushion".



Torment well, before calculatingthe transistor Q800. Call normal, but under naprugoy terminates. And stillconfused churned that the scheme based on Q801 indicated 0.6volta and match,and if fed to Q801, the picture becomes less, but the cushions were. The factthat the image grid "broken" does not pay attention. This is mygenerator gives a picture (sometimes).

PHILIPS 32PW8609
Violation of the geometry after heating.


Hello, Dear forum! The problem isthis:
TV PHILIPS 32PW8609 / 12S chassis A02E AA after buying regularly worked forabout a year. Then the image is gradually narrowed horizontally, mostly after awarm-up. Over time, the defect progressed, the picture is narrowed more andmore, there pincushion distortion. At the moment, the image is already after 3minutes, significantly narrowed, and after 10 minute warm-up is shown in thescreenshots (attached files) and the character of distortion varies dependingon the image (in bright scenes is enhanced). Tell me what direction to look fortrouble. I believe in a raster correction circuit. (Search Forums enjoyedsimilar themes explored), I would like to know more what to check first, aswell as at least a brief correction and the principle of line scanning in thisTV. I understand lowercase electrically connected to the network? Where doesthe power supply 141 volt line, and whether it is stabilized as either? Thanksin advance for any help!


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

So the repair does not start.
Measured + B, the voltage on the transistor correction before and after heating, a pop-Osu.
Further, only the tank.
About all the work performed, rather than thinking in the subject.

+ 141 volts, as indicated in the scheme, the capacity of 100 * 10 in the correction scheme replaced. To no avail (((

DimichNot ukapyvay box. [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة] Chassis brought in for repair, make, will continue to watch. Oh no, I really like something he)))) I have a suspicion of optocoupler, it is slightly heated soldering iron - raster considerably narrowed.

For me, optocoupler - 100% of it! [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]


Yes, it really wasoptocoupler TCDT1102G - a typical problem. Replaced on TCET1102 - analog, inanother case. Additional adjustments in the service mode not required. Now boxon the run, shows normal. Thank you all for your help! Locked.

A couple of days everything together, and then can not yet get to this "box". Force majeure! [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]

Replaced all Conder to trim personnel (on diet 28B, voltdobavku, and output to the coil). Was better, but still a little visible light band.

Replace all personnel ms. for complete clarity.
Conder on the ESR and capacitance of at least checked out?

Change the micro personnel

ESR is not took it for

It has long been micro toss was possible.

8mes later ...
I picked up Ustroch 148v, and now look at this TV at home with a side of the screen for more than half a year.

And adjusted the filament voltage, or wait until the kin izdohnet?
Personnel change was difficult?

It turns out to give the client does not need, and himself, and so will do. (It was such garbage TDKS "left" to replace the set is true in LG).

Changed in the MC-1 (A5) C9 - 1000 uF all returned to normal, but when you connect the receiver to the dish through the low entrance to the IDC-2 A1 (the so-called interface unit televisions of the older generation), breaks the picture from center to the left - right .. Trimmer at LF board did not change the result. Question one! The trouble in the board of the bass or something in the module channel. When vyklyucheii signal receiver - all with a simple antenna works great.

  • Hitachi CMT 2141 In the picture purple hue.

  • An old television set, consistingof: per cent. M34300N-555SP
    Video NA51339-SP3, UW-transistor
    In the picture there is no green color (purple hue), the green gun is in order.Video amplifier operable. Replacing the decoder SECAM (AN5635N) and videoprocessor, the results did not produce. The measurements of U on the curves.1-3 (RGB) decoder, we found understated example. Ex. green gun (6.5 in),instead of 8c-9c - why I can not understand. Terminated by the equivalent of UW- the situation is the same.
    Maybe someone faced with such a defect?


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

Excuse me, did not notice that the purple color.

Try checking the contours of the MP, and preferably oscilloscope trace of the signals at m /

Checked at the decoder "mikrushki" - they are dry, and everything was replaced.
Locked.

  • Philips 32PW9509/12 Paduzhnye band.


Photos from your mobile phone,really. This is the "blue" screen when turned off the antenna. Whenviewing the color "stack" with a picture. Not like the picture tube,as bands vary slightly by changing the location of the plot, the brightness,format the displayed image. The focus and geometry images are not violated.Disabling loop degaussing degaussing CRT yielded nothing. Honestly, I neverencountered this in large tubes. It was once something like a dead old picturetubes 51-54 cm, but then had fallen or exhausted the resources of a rainbow andthere was not so bright. Please help with the direction of search.

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

I encountered this problem only with SAMSUNG.
After checking it was found that there was no voltage field sweep.
The reason - loss of jumpers (Cutter 0.1 ohms). After replacing the performance was restored.

Read carefully:

The focus and geometry images are not violated.
It seems that on tv. strong magnetic field of the earth, (or close to the working example medpribory) Try moving it to another place, but if does not help then you need to insert himself probyvat kinescope.

There was no stress field sweep. How's that??
Naprugi on the frame there, and telly shows such kinetics on? Sam said he understood Th?[ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]

TV did not fall? Acoustics is not standing next to?
If there is no deformation of the mask, it is a very strong magnetic field. We have to think where it came from.
Prozondiruy wasp.
Furthermore otklonyalki that still hung on the neck?

I would have to start a home loop degaussing disabled.

So he also wrote that the loop off. [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]
Although anything is possible - disabled, then turned and started to demagnetize. And there posistors with a hole, and runs the break itself on a loop ... [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]

And you try, for the sake of experimentation, turn off the frame.

Only through the bases of kinescope everything will fall into place, although I am more inclined to peel off the mask at all what was done above.

I agree, too, have seen recently is the same. And the demagnetizing and Hos me and just replace kin put everything in its place.

A video amplifier as food, watching?
It seems certainly to kinescope is likely the way it is, but all the same:
decreased the accelerating voltage, drop on the neck of cathodes (cross-check on the modulator board soldering, do not forget to see these separate cap neck, accelerating voltage) and somewhere in a 1 kilo closed cathode (either) to ground.
You can not just throw a picture tube that sometimes problematic, and other gear under the picture tube, even at a diagonal (54, for example), the raster will be given the small square, but rather to assess ...

Knock on CRT WHEN THE TV AND UVIDESH MASK OR NOT

Columns did not stand next to the owners swear that is not dropped, live with that failure for almost a year, it seems I'm not the first artist who looks at a picture etu probably all declined. Because of the limitations hosts events associated with the occurrence of fault surges in the mains. Box at home at the client, well, that there can be done to yourself until you take it. I turned off the loop degaussing image rotator, and then demagnetized kinescope, all that remains. There's still a lot of reels hung on the pipe: there is a circular magnets information, slim, well and lower the staffing is not disabled. Would be a picture tube, framed like. For some reason I do not think the mask: the prostukivanie not respond, changing the scale (size) of the image, the band also increases proportionally-reduced. The impression is that the source field somewhere in the region after the guns, the operating system. That there may namagnitititsya? Right now poizuchayu still shemku.

The reason - loss of jumpers (Cutter 0.1 ohms). After replacing the performance was restored.
When the power supply personnel bipolar, then disable one of these meals can take away screen up or down, which can cause a flare screen, even with a "rainbow", but the brightness of the "rainbow" will be smaller than in this case, and the author writes, that the raster image is - and this is clearly exclude such an option.

Sony KV-2185MT chassis G-3E. Ingredients: per cent. M34302M8-611SP, Tuner - BT-RG321,memory - 24S02, HR - LA7830, BP - STR-S6307, HOT - 2SD1877. Video - CXA1213BS.
Was broken line transistor, after replacing the transistor capacitance 1mkf50B, line start up but this picture, what would be thought. I am new ham, so Iwill be grateful to the advice of a specialist.

Sony KV-2185MT
Problems with the image.


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

And specifically what you want? The same model and same problem? And Schaub issue was with the photo, yes? [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]
, It is a fairly common problem, and not just for Sony.
You my dear for a start, we need to understand - WHY flew HOT.
Or begin to "literacy campaign".

That, and he kinda figured out from what NOTsletel, kondesator changed - it is logical from the capacitor on this chassis Noti dies.
But regarding the rest, there Duc radio propayat thoroughly necessary.

And at the expense rations and ESR is my firm almost in every topic. Kudazh already on. [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]

It would not hurt propayat TDKS and change Conder collector of music.

<Previous unsuccessful you have left. Propaivay feet shemales., And in general - all Wed [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]


In any case - Sonya will benefit from this.

Thank you for not sending all of the studio. Why flew HOT I figured out the line propayal, Conder checked, electrolytes changed. Voltage is normal. But the failure of nowhere weeks, and if you turn on TV it within five to ten minutes, the image comes back to normal in the vertical from the center to krayam.Porylsya in the internet like a fault, the replacement of quartz, but is not at hand, and whether in this case. Therefore, the question is: what chain are responsible for synchronizing the lines or in my case is not so. I think, or capacity, or nepropaeno. I'm a beginner (was once necessary to begin).

Check Conder and diode on power supply lines.

Conder checked they do not need to check and me!
Check Conder and diode on power supply lines
I think, or capacity
right thinking

As a beginner you can think to type in search "ESR", And read. And you understand everything.
Electrolytes WHAT checked??
SR, KR, IP - only the replacement of new and proven ESR.
There is not only a string soldering is necessary, but ALL telly!
To know what the chain is responsible for synchro then you ought to read about it in clever books. Practice without theory - 0.

Check Conder and diode on power supply lines.
There is a view of the literary output PSU, something like 150mfH160V (exactly on the scheme or pay to see) them there by the way the two. And isho Network Bank moget a spoiler to give. But can be synchronized easily. And the telly this year should, as a rule almost the entire (and preferably whole) propaivat, to measure and change in BP and LTL Wed In personnel often too. A supply voltage power supply and line is very desirable to control the oscilloscope, for the beat - just-be, and saw in naprugah-whether the case. And if you are already discharge the same rate, then have to think about sync and master clock reading the course of her .... and in general about the telly. But first propayka and stress - that's as Our Father! [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]


Oh yeah! And it is written here - propayka radio. You see, to not roll the - all one - all the telly propaivat be [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة] Because a hundred-and-arenky it. [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]

Stress need to measure - well, as without it. Rolled his would be a simple probe output power supply during the manifestation of the defect is clearly something to be figured out.

Well, with this defect, it is clear, but I had to repair sony, tact there TDKS zadrachival, but the truth is not such a big hatchet was, but still. Waved him - all excellent. But there is a direct dependence on the brightness!

You should at least streak sfotkal.
And in my experience, if the heating is something normal, something to blame for the electrolyte. [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]

Cause found: guilty electrolyte s875 4.7 mF 50V, replaced and television has earned right.
1. Replacing the row transistor s513 1mkf 50B
2. Replacement of R806 1,5, R803 2,7 a, R804 4,7 to resistance decreased in the smaller side.
3. Replacement of electrolytes on nutrition, and all who stand beside radiratorov, propayal fee.

Visual defect in the accompanying picture, had a similar theme, but without asolution ...
Changed Litas: network, line, round frame and herself (STV9302A). Roast itproperly, even by 12,-12V visible ripple (1,5-2B), in otklonyalke increasednoise. And the impression that the frames with rows where it mixed.
On the procedure of direct and inverted signals are slightly different.

In my practice, many have been with the deformation of the mask and the outer loop mutations both rozmagnichivanii nebylo, but as you see here to see prices.

A OTL work out? And if you turn off the telly and turn on after 5 minutes, but with disabled loops - the purity of the field is stored?

The second point - while turning, the loop connects jerks.
Ie somewhere holds nekontakt. In the same relay for example.

And the fact that you included with no loops and cleanliness has not improved, then this is the result of an external magnetic field.

Problem solved!
VV nekontakt pushed on the relay and although it worked, and decided to replace the relay and posistors simultaneously.

That's amazing! back to the previous set of good and put the field geometry, cut off ten times to the network and included.
Set this shot, looked inside no signs otgorevshih contacts, all as new.
Solder ische in customer obnovlyal.Zametil difference only in the relay clicks, the new switch is turned off somewhere after 7 seconds, and the old neskolkoi once clicked.
Conclusion! that customers are looking telly with spilled electrolyte, occurred kakoeto circuit and mask from the loop rozmagnichevaniya very namagnitellas. Then the relay and posistors gone wild ... and more nepropuskali current through the loop.
Magnetic field outside the loop was not enough to relieve zamagnichevaniya.
Thank you all for your participation. Zarah Thanks for the help.

Probably all the easier - when you turn on network TV button loop degaussing did not demagnetize as magnetises kin.
Do not forget that the defect arose during the throw voltage. Burnt some element in the chain of demagnetization [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة].

You were asked to remove the parasitic modulation of the feedback, a 32 foot videoprtsa,
delve! If 8659 does not see (obr.svyazi) with vyh.KR he does what he is talking picture (make sure this whole conversation, start with 32 feet as it reacts). Just in case
Keep in mind 18 foot entrance to switch 50/60, but with a picture IMHO is not too
actual (not much of any groups of rows) again ohm resistors (to ground) capacitor-replacement!
To do-something must be done! UV!

It is, put the chassis brought into place, and a "miracle" everything is OK. In my experience, first time poster otklonyalka kin do not like, though shaski often had to carry. All thank you for your support [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]

Check the lower coil.

It's time to repair EW, go to the service and take up the scheme, it is enough ..

MO drives off, the reason given to see only the author. (Even indirectly buffer)

It looks like from a bad filter on Nutrition "open" is.

In the presence of an oscilloscope, this byaka should be visible right away, I speculated on why the author does not see it. [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]

On the oscillation may not be noticed, but yark.kontr.pokrutit stands, there was something like that from kin
I do not remember in detail (leading, not the delta gun)

There was such a picture, H-out carefully to see the waveforms. There was a case when you touch probe pin. H-out, the picture was restored (it's on videoprotse MC4402P), remove the same thing (and had to put the equivalent. Chain input. OCAN. Oscillations C1-65 R = 1M, C = 30pf.) Do not have the time to understand (it was on New Year's Day) and runs until now. [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]

I apologize for the delay, the unit brought only this afternoon.
Again tested waveforms at the collector HOT, on the connector running in rows.
Form of "bell" is ideal as a textbook. PPE with 33 O and D101 to the base HOTa without any
changes both during normal TV, and in "ghosting." While searching found out that if the touch
probe findings 12 MHz quartz fault manifests itself quickly once involved with a "cushion".
Updated replacement: quartz 12 MHz, capacitance C405, C404-47pF, D808-7808.
When working from an external video neispravnosttakzhe manifested, so that malfunction of the radio channel is eliminated.
Tried to accelerate the manifestation of the fault phenomena, but perhaps this problem is not related to overheating anything.
Tomorrow, if it comes out to check Podkin processor, and to exclude Lajoux from another source BS
supply, resulting accomplish your goal.

Try to link with the current beam will fall off those extra questions and recommendations.

It would be nice to see the waveforms at the points of connection VD705/VD706/L703, and R723/C707/L703.

VT702 and shorting is a fairy tale. But the problem with the L704 it looks like not a fairy tale [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]

Colleagues, I apologize for such a long absence from the forum. Was forced to leave immediately. This morning I again went through all of the alleged defect sites. While raking the other boxes, tossed a fee to another picture tube to prevent the operating system. Not a wasp. Dawned spare time, went into the network and looked at a forum.
Thank you for your good advice, especially zarah and samsad. Previously tested signals only on the OS and there was no difference can be seen now looked correction circuit and now in L704 has anomaliya.Foto prilagayu.Kstati, zarahThe signal at connection points VD705/VD706/L703 unchanged.

It seems the fault is localized. Today is removed from the donor L704 and put it on Rawls. Five hours worked without any problems. Pomery inductance of the device-310mkGn. Under the scheme - 450mkGn. Tomorrow will try to rewind the throttle and drive out the TV again.


Today, television has worked full-time, so that topic can be marked as solved. Fault found in the L704
Thank you all!.

Never seen such a device.Ingredients: microcontroller M34300NA-012SP / Signal Processing LA7681 / videoprocessor AN5635N. Such trouble, the screen Loch, and the impression that nocontrast and brightness while vykruchena to failure. Video Amplifier checked,no scheme . Here's a picture
Who has ideas tell me. I like the chassis until it encountered

Well, as with a supply voltage video amplifier?
that the RGB output from videoprotsa?


And the accelerating U tried abated? What happens.

AN5635N is not VP, and SECAM decoder. I have a second week is Hitachi CMT2153, with the same controller, and a decoder as you have, in my case there was no SECAM at all, replace the built capacity in the circuit SECAM ident, color has gone, but like you, if you unscrew the saturation of the whole , then fill with color and to the same is not green, although the UW are working, may have an idea? Scheme I have found.

Gentlemen, colleagues, thank you, all!

Similar to the modulation of HR saw.

So it is, but why raznoyarkost lines?

Lines closer - brighter, more - darker. [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]
