Yes, all Pitalov in normal and image without distortion, CT 972 and me, for AV is not checked, now gone.


Network bank has changed, no change, tried to connect to AV also unchanged.

I did me when I MUSIC dostoval yet.

If there is an oscillation, then look at them naprugu S701 (whether saws). Not for nothing after all heats.

That picture is not bad - not at all clear line noise from the chassis if not from outside?

And you have a speaker connected? I once something similar because of the VLF was dinimika disabled and looking for interference on the video. (VLF and excited!)

Of the loop is indeed possible. I was in my practice, such a case. Only there were wide strips about 2 cm, darker than the iso, and moved slowly up and down. A defect lay in the fact that the second anode "burnt" mikrodorozhka directly to the loop, made a hole there, and "through" there. Disables loop - the picture perfect, includes - and this crap. Posistors thought, changed, nifiga ... then looked closely - there is. Track varnished, loop insulated. That's all. [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]

Less commonly, the capacity of Nutrition tuner next to the tuner.

Conder said that about +This contrast of the S117 and S422 12V tuner, vryat whether they are guilty. Check C702 and R704 are parallel to the primary TMS, I do not like that S701 is heated, if it is 17.5 volts, it should not get warm, the oscilloscope to look that it is happening.

Photo view would be easier to identify. In general, suppose he shall take off the antenna and the AV cable and see the results, but after KRENok ostsilografom look could bring?

About the photo and about AV is written above, read carefully! I doubt that he is stuck with the telly cable repairs. [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]

Fades the image on the left of the screen when the reception from the antennaand the AV, without a signal on a blue background, too.

In the photo three horizontal light bands, but this is due to shoot with mobilephones, in reality, pure blue background.

All food is normal, with no ripple.
On the video amplifier - PIN 20, 21, 22, clipped signal goes along the lines of
The inputs videoprotsesora - Yin (pin 39), Synh in (pin 38) signal is normal -no cutoffs
The video processor changed
Almost all of the electrolytes around the GPU has changed,
Just in case, changed the firmware.
No change at all manipulations.

History. Prior to my joining this TV doing: looking for
cause departure D1878. Made: to replace TDKS
SJ28069-00BJ1 (new). The result - zero. Took charge and was returnedunrepaired.
I was invited. Examined the cost: M52343SP - payana, quartz at
503kgts no 24S04 - is on the socket.
Posed quartz and D1878. Bklyuchayu TV: 5 sec thermal breakdown
with D1878, a high voltage has not appeared. Turned
faulty TDKS. Replaced on CJ28069-00AJ1. TV starts, but
there were problems with SECAM. Nutrition 8 volts clean and stable. M52343 -changed. Gating pulse to the 12pin
M52343 - as in the picture. But this is what saw: when the probe
ostsilografa touch 12pin, then SECAM is perfectly attuned.
What's the problem

It is you to be confused with PAL. One of quartz (4.43) - for PAL is used,
and the other for NTSC. These quartz can be thrown out, but not on SEKAM

It was something like that. Once upon a time put the decoder in the MP-3, the submodule on the TDA4555.
So the PAL and SECAM was great about the uncertainty at the old
submodule everything was normal. The whole thing was a strobe (not like he specifically this chip) on the waveform is no need to quibble. When the probe spit the color returns to normal output - put Conder at 100 peak on the mass of all was OK

In the photo such as the alignment is shifted to the right? Perhaps because of this flashing? Contour T121 does not work?

Meal you checked only a matter of how, and why? At least one literature was proven value and ESR? Gating how it hilenky, the lower shelf is narrow, and the scope of 4.5 volts, not enough will. At a minimum, should be 8V.

You have so much advice was given, and you're ignoring. You impulses KIOH, SIOH - watching? They do not have to look at the gate! Percent could not do the normal gate, if it comes abnormal impulses.
You replaced TDKS, and I am glad that the defect had disappeared. And what was the reason? Measurements at the same TDKs make the same lazy. Underestimates the voltage on the staff could lead to a deterioration of form KIOH (important - their wrong duration), And this could lead to a problem in SECAM.

As an option: the current Chinese potribleniya TDKS more (you can check with an ammeter), resulting in changes mode power supply, which leads to gamonik affecting the RF component video, and as a result - bad color recognition.
You can still fantasize, but I would first check this version. Especially because the character is similar to BP, see the topic above

reason about the SSC being crucified? Is it so difficult to read as a general SECAM formed, and what is the flash, and where these outbreaks are. And do not wonder why the SSC is a tricky form?

After that drew attention to the image (horizontal lines) is slightly rotated afew degrees clockwise vertical lines are straight, see the photo, adjust whatwas on the board, not what is not given, they are not affected by this problem,replacement TDA3653B, and non-polar reservoirs in TDA3653B stud is not what isnot given, the operating system is not broken sits on the neck like Merv, ringsinformation does not stagger the magnets will not fall off, replaced 2sd2482also not something not given, the voltage B + 105V, the other from the outputs ofstabilizers 78hh in normal TV is already running more months, no other symptomsof did not come out (not burnt), not particularly what is not heated, the TVworks like a clock.

Whether it was to say something I can not because machine was donated to thecountry-that would get used to the ground I only know that when you turn to a particularly on the image,not what is not conspicuous except one, that an hour was lost image, and thenoff / on to restore it, and repaired for days rabotet without failure, just gotout the above-mentioned distortion does not change with time.

Tell me because of what may be a distortion, or may be it can be something youcan adjust. (In the newer TVs have a function rotate the image, just a fewdegrees, in this TV this unfortunately is not).

Thanks in advance all the answers.

Came to plow the track, some torn- apparently changed NN5198, colors not found in any Palestinians in SECAM.Chip runs cooler 50-60 degrees. (?) When you switch from console to manuallycolor system, a slightly different hue. Voltage is normal, firmware tried topour, does not help. Holidays on the nose, and did not want to leave the clientwithout telly. Can tell something sensible?

What is a "shade"?
Do you have an oscilloscope, you can view the diagrams?

Can make the initialization of the processor. If you switch off the TV. simultaneously press the MENU button and VOLUME + on the face, while holding to the mains.
Recommended after replacing NN5198K.

But generally - Human [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]

Replace the processor to do initialization and finalization of CPU power to stem HVcc. Voltage on it should not be higher than 6.2V. Warm up will be less.

6.2 volts is clearly a refinement made the plant, and a resistor, and Conder.

Then do the initialization. With the new processor will be the same.

And how to do it for this procedure? (MN1873287JJ1). Tried MENU + VOLUME "+", does not pass.

Podkin quartz color.

A lot of the "Left" and chips with their problems. This is much more expensive - it is written.
My opinion: if the chip works in the "mode", ie by postoyanke okay while heated, then the cause of most

Quartz has a pop, not that. IC took over 9uev, "Synthesis of Sevastopol, they usually left the details if you just warn. Or maybe someone in the course, in the service, there is something in color, but it can not enter, probably because I have a remote Chinese. While trying different firmware.

Nepropaya saw. Kondyuki ... What should I do? Telly was 2 years. Decided to do.Resolder line, personnel, decided problemma pincushion image. ULF After joyfulunderstanding that the telly works noticed - interference that varies withtime, but not disappear. When the telly yuzalsya were such interference, butdisappeared after 20 min. Decided problemma, propayav connectors block 100Hz
So will advise?

I have on companies such as noise - if the telly is near, and from room antenna plow! [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]

On secondary housing all kandyuki me. But instead of 12.5 is 11.3. On the AV board - 7 instead of 9c. According to Bass, such as interference.


It, it! I tried to block changed from 70DS-1915 no interference, but the image on a light background. Memory also changed. (No longer display AV input) on the old model, it is one ... But here and firmware to be changed, I think so. I have a 100Hz cure. I'll try kondyuki.

A smd kondyuki both fail. Or are they just short-circuit making nutrition??

Fault they do, the tester can "call" normal, capacitance meter the same way. Or electrolytes me without looking or check ESR-meter

Yes, I realized where I was! I mean SMD capacitors ... Che with them can be, generally?



Really out of - for LTL in this block such interference .... Or is it true, types of diseases!?

And we're about SMD capacitors ...
They have, besides the loss of capacity, increased ESR (Equivalent Series Resistance)
Tester did not measure.
Disease typical for similar units

wrote:

They do not touch.
Vypayay couple of LTL, the more capacity, and tell what their loss.

SMD reverse side of the board are. Such small. They are nonpolar. 10N 100N, etc. I'm talking about them. A blue kondyuki changed all tomorrow!

smd-electrolytes me, small smd-"boxes" do not touch

Well, well. [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة] As it climbed into the boxing CUC1824, all without exception reduced in capacity. It is easier to change.


Guys, replacement of capacitors has solved the problem. How to add a theme to the section - Troubleshooting on images?

Geometric distortion of the raster.



Dear Colleagues, Does thatZaneta, not stingy, and do not count for work report: where hidden defect!(Scheme I have no: (()

Thank you!


Here you can place the means ofrepair systems correct the raster method of repair and restoration of healthschemes and components of EW.
As well as links to ready-made solutions.




The unit came with areduced horizontal and pincushion image. Fault was nepropay capacitor S630.After propayki image has increased, but it became too large, the pillowremains. Diode modulator tested, capacitors, and in general all that relates toEW. Managing Amplification collected on Polevikov standing on radiaore. Radiatorquite cold. The impression is that the diode modulator is not controlled. Q:What should be the gate Polevikov and what voltage postoyanke? Lost in broaddaylight.


TYPICAL PATTERN ADJUSTMENTS EW diode modulator.

The resistance of the whole, the video processor is also changed. I interisuyut ostsilogrammy. What electrolyte you mean?

Tear Polevikov, the image must be smaller than the screen edges and podushkoy.Esli this does not happen - look where techet.Kosvenno Polevikov cold - a sign of leakage past it.

Remove the 2.7 ohm, be sure the amount was minimal. When shorting the lower diode is maximum. Means a defect in the correction amplifier. Ostsilogrammy not look here, but usually they look like neotfiltrovanye 50 Hz when the amplitude of the bridge. 0,1-0,5 in. Cond. Polevikov need to be replaced in the first place.

Oscillograms here helps a little. Typically they are purely indicative.
If the scheme is the same as you pay attention to details of the capacitive divider C 3, C 4. L 1. If the throttle and has a large "large" then the circuit inductance mood (in resonance), maybe he Vítkov. Effect Polevikov can check on the move, first by closing the C 4, then the bolt (G) on the hull.

In these SONY above in Scheme Conder S412 - 474 (0,47) I change neglyadya if only hint came on the pillow.



I've forgotten that in Russia the problem is called a pillow.[ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة])) So, and wrote in German, with easy transfer.
Thanks for the tip-off to the diodes ..! And if there was anything specific name for this model?

Thank you!

burned down the resistance of the circuit and DPT TDA8350.podkin resistances if burned Change the 8350.prover that above written.

n this case, the output stage of correction in one case with personnel TDA8350. Poєtomu at breakage of the resistor chain correction, first check the diode and, then, to assume a chip

to make sure that the fault lies precisely after mikruhi, podymi in the air 11 feet and a closed circuit to the ground, if the picture is not exactly what razehalas after mikruhi
circuit device is not, so writing in general, I think the problems should not be!



look, do not posodi on the ground 11 feet!

Thanks friends!

Everything turned out. R 503 - loss of, well, D 434 replaced. Stands on the run ...

Akai 1407D. Well-known long-defect: the vertical damping poles. Butin this TV is so pronounced that he could not help but put on public display.In addition, people are looking out, and probably listening to this TV, broughtup the fact that these bands are visible even in the off kinescope. The problemis solved by replacing the electrolyte S436-22mkf\ 160V.
