Hello Friend. see if you have more serca filters from the regulator, for example, one of 47ufx50volt. and smaller change them for new
Thanks Manolo I already changed the c814 filter from 100uf to 35v and the c822 filter from 1uf to 50v and it didn't work out just as bad I also changed the optocoupler q802 because when I heat it with the tip of the captin it turns on and it didn't work either
Thank you, colleague Manolo, although I did not mention it from the beginning, I had already warmed the regulator and it did not work the same as the other two that are close to the Chopper, it only works by heating the ones I already mentioned
friend. Check the zener diodes may leak. I mean those that are close to the filter that you indicate when the TV is heated. turn on
Hello manolo, thanks for your dedication in this case, you gave me an idea to find the fault was the C830 filter from 220uf to 25v which was devalued this filter is responsible for smoothing the voltage that comes out of a chooper pin and is going to connect to pin 1 of optocoupler 803. Thank you very much for your help.
If friend Manolo with the change of the c830 filter it was perfect, thanks for your collaboration
