SONY KV-35S26 Blinking picture


Guess I should have looked throught the next couple of posts... The problem you have there you will not be able to repair yourself but a good shop can fix it temporarily. The CRT (Cathode Ray Tube) or picture tube is shorted, that's what is causing your blinking. You can call around and ask a shop locally if they can rejuvenate it for you using a crt analyser. In the shop here we use a BK467 which would fix the problem for awhile. What they will do is take the back off and hook-up the analyser and remove the short temporarily. That fix could last weeks or even months, in most cases though never more than a year. Turn the RV1791 back down, it has nothing to do with the G2 voltage and you don't want to overdrive the crt anyway. Take it back down until the horz. lines disappear in dark scenes or background. Then take it in and have the picture tube rejuvenated. Then start shopping for a new Tv... You'll need one eventually but this will buy you a little more time.

Sounds like the high voltage is marginal.
My experiance is to not put money into a TV that is over ten years old. TVs stress out their electronic components worse than almost any other electronic product. After 10 years, there are so many parts that are ready to fail that your are probably wasting your money trying to get any more life out of it.
Another option is to wholesale replace the main board by sending it to Module Exchange at 972-298-1212,
or PTS Electronics 800-844-7871 ptscorp.com.
Be careful on buying a new one though. Often times, these new technology ones are much worse. Always Google the model number of the set you intend to buy and add the word 'repair' or 'complaint' to see if it is one of the many models that are customer service nightmares being produced by even the most reputable companies today.
Hope ya fix it!
