Was a sign it needed service. Get estimates since the failure is now a hard failure.
I have an LG 50PZ550 plasma TV that is giving me sound but no picture. When it first started doing this I could get it to work sometimes, just turned it off and on again and it would eventually come on, and when it did work the picture was perfectly clear and fine. Over time it took longer to get it to work and now it won't come on no matter how long I try. I believe the last time it did it took 20 minutes to come on. I have tried replacing the ysus and zsus boards but neither of these have solved the problem. Is there anything else that I might try to get it working again? I really like this TV and don't want to spend another grand to get one of the same quality.
