Tv phillips 20pt529a / 55r vertical a bit closed
Check the resistance of the vertical erapa deve aver a devalued and change filters of the vertical especially the large and the output to the yoke
Thanks for answering. Notice that I already measured all the resistances and apparently they all mark an acceptable range. The filters have already changed them all
Yes, you're right! I meant that they are apparently in good condition and at face value

Friend, my recommendation is to detract a leg and measure them because in the form it gives false reading
I have some screens with everything and yoke of some phillips I think I have to take into account the value in onmios of the coils really.
Hi. When entering the mode I served in the adjustment of vertical parameters these by making vary their values have an effect on the image or not?
If they take effect. You can see how the image runs up or down depending on the setting
But nothing else in the box of the image that is seen and not influenced by anything to upload the image to the side up that needs to be filled on the screen
friend this is the part of the vertical do not take it badly but check again the resistors and diodes and filters that Indicates replacing filters with new unused ones and the resistances are not undervalued and confirm the supply voltage between not dropped
Friend, I just noticed that horizontal geometry and vertical geometry only shot me vertically and it didn't give me another option
Friend Luis tartagila apologize note that I told you that I already found the option that you told me about VAM and if it opens the image but does not completely fill the screen. Apologies
Nico is well suggested. But it's weird that I can't adjust the way I saw anything.
do this test ... maybe you just need a resistor to solve the problem ... uvica the R3471 and 3472 temporarily weld a 3.3ohm and will open the screen more ... if you see q, open a lot take it out and try with a 4.7ohm or try a 10ohm ... the one with 3.3ohm is (orange-orange-gold) the one with 4.7ohm is (yellow-violet-gold) the one with 10ohm is (black-black brown golden) cheaper and simple can not be ... comment results ... ok ..
hello colleague Luis Tartaglia ... greetings ... this, I suggest to the colleague is xq, he said that, I enter the service mode but without results ...
it can happen that sometimes it cannot be solved from the m, service ... or maybe in this case if ... but instead of looking for so much with a single resistance it can be solved ... it has to be the value suitable since. R3471 and 3472 may have lost their original value a little ... greetings and ... Happy Sunday ...
That friend nicomena, notice that I did what was suggested and indeed the image opened completely only that everything looks stretched with black lines. Notice that at the beginning before giving the image I throw three colored lines where the image was previously
well: x that will clarify that, you will test with different resistance values ... I do not know what, you put value but if you stretch a lot and the logos of the channels are off the screen it puts another resistance value higher ... try with one of 10ohm and take out the q, put ... comment q, value you put ... first there is q, find the appropriate value and q, the image stretches us beyond what is necessary ..ok..new with a 10ohm ... (brown-black-black-gold) and comment results ... ok ..
Hello VICTOR colleague ... greetings ... thanks for your support and solarity with us that, recently we started in this forum I repair ... I congratulate you for such a long career in this forum and to so many colleagues who have helped ... greetings and happy sunday in the company of your family ...
Hello friends, what I do not understand is because if I change the resistance for the value that is the fault persists
Good. Friends change the R 3472 and 3471 for ones of the same value and the fault persists, just put another resistor in parallel of 10 ohm and do not open the image but I put a 2ohm and if it opens but the image very stretched and nothing is looked at I already put one of 4.7 and it still looks closed
What value did you put resistance when it was possible to see stretched image?
remember that you entered servi mode and expanded
place the R again where the stretched image was seen and go back into servi mode and see if you can reduce
Hello colleague LUIS: that was exactly what, hiva to suggest ... put a parallel of 3.3ohm or 2.2ohm with the R3472 and R2471 and enter the service mode and see if now it is possible to shrink the vertical deflection. ..xq, it cannot be q, stretch as much or shrink as much ... and if the OSD does not appear as you do to enter the service mode ... it will be q, when stretching so much the OSD is not noticed ... ok .. .Try to correct from m, service ...
Well friends, I commented that in the end I could not reach a specific solution, what I did manage to do is open the image a little in service mode although the osd was not seen from the bottom but that is how the friend who took it I was repairing. I forgot to comment that to fill the image I put an R of 4.7 ohm in parallel. Infinite thanks to all for having the intention to help God keep them and until next time
