quick setup; In our computer/video gamer room, I have a TC P42S2 made in 2010, plugged into a decent Panamax surger protector/conditioner (about $80). We have a storm short, intense storm that didn't cause a power outage, but might have created some brownouts/surgees. In same room is a Dell descktop plugged into a Tripp-Lite line conditioner AND battery backup.
I come home from work and the plasma is dead; no clicks, no LED flashing, totally inert. AND the Dell has no output coming out of the video card-outputs (but it starts). Turns out that was a dead video card that I replaced & now it's fine.
I did a bunch or research...found this thread & others. and I keyed on the power supply board I tested the fuses...fine, I wasn't sure if I was testing the MOSFET properly, but I think it was OK. But hearing all the stuff about the power supplies, I got one off of ebay$40 delivered (from a vendor with great/voluminous feedback). Just tried it out....still no sign of life.
To me, that signals that maybe it's the main processor board...the one that has the switches attached to it. But before I replace it blindly, are there any things I can do/test to see where things are going wrong? Maybe there's a way to see if power is being sent from the power supply board to the others?
I love the panel, and I'd rather spend up to $250 repairing it than getting a new $500 set. Thanks for any help you can give me!!
