I've got a 60" Pioneer plasma PDP-6020FD that won't turn on. It clicks like it is trying to power up, but then stops and shows a sequence of two blinking red lights. It doesn't get to the point of displaying a picture or sound. Some preliminary research led me to believe it was a power supply, so I bought a new one in hopes that simply changing that would fix the problem and avoid having to lug it to a repair shop. Unfortunately, the "new" power supply didn't make any difference. However, I had doubts about the power supply because it wasn't packaged very well. The tops of the capacitors were rubbing on the bottom of the other half of the power supply board (it is two pieces on this model). I don't know if that would create a functional or just cosmetic issue, but something to consider.
Since my initial attempt wasn't successful, I set upon trying to find a repair shop. The only shop in my town that would look at it wasn't familiar with Pioneer plasma displays so it took him some time to diagnose. I was not happy with the communication and level of service, which led me to doubt his diagnosis. He said it needed a Y main and upper/lower buffers. I did not proceed with the repair because of my doubts so now the TV is back at home. There is a repair shop with a good reputation and who is familiar with this model, but he is an hour away and this TV is a beast to move, so I'm hoping to do a bit more diagnosis myself if possible.
I found some other ideas after doing more research on this forum. First, I unplugged the Y main harness, which yielded the same sounds and now a sequence of four blinking red lights. Next I plugged the Y main back in and unplugged the X main, which made no difference to the original symptoms (same sounds and two blinking red lights). It didn't power up enough to be able to try to find an audio signal.
Are there any voltage checks I can do to further diagnose this issue? I have a digital multimeter and intermediate electrical skills so I am confident to attempt a bit more in depth diagnosis. Thanks in advance!
