TV Repair Questions? Ask a TV Technician for Answers ASAP
I am sorry you are having problems.
My name is ***** ***** welcome to JA!
I will do my best to help you
Can you look for bulged and leaky capacitors on the Power Supply
OK, the next part to change would be the Main Board, there is not much inside these TVs as you have seen
I have an ESR meter to check caps, sometimes the go bad and you can't tell by the outside, but it costs about $200 (160.75 GBP) for the meter.
No problem, good luck!
