Facing TV Problems? Ask a TV Technician.
Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
That sort of problem ('jello screen' as it were, with quivers and rippling) is most likely to be an electronics problem, a board.
Actually, it could be a defective filter capacitor in either the power supply, or on the boards. That is most likely, if the rippling is regular and constant. If it is irregular or variable, not so likely.
To spot a bad capacitor, look for signs of overheating (rare with caps, admittedly), or more likely bulging tops, or leakage of fluid from the capacitor. Replace all capacitors with bulging tops and/or leakage... those are bad caps for sure.
Thanks for posting the pictures!
I'm looking them over now...
Picture quality is very bad, beyond a doubt.
Not being terribly sure, I must say, but I should recommend looking for bad capacitors (a very common problem in modern TVs) and also it might be a defective Y-Sus board, but also it could be a wrong voltage on the power supply (which is why I recommend looking for bad capacitors first. Esp. in the power supply board.)
