Hi, I have a Panasonic TH46PZ800A (2008) that is completely dead. No picture, no sound, no relay clicks, LED flashes or any other response on power up. Following the Panasonic flowchart for No Power/Dead Unit leads me to "Replace the A Board". I'm scratching to find a spare A Board (P/No TNPH0712[1][A]DA), new or used. Has anyone had experience with board level repair of this board or similar?

Hi everyone

I have a LG plasma with the dreaded relay-clicking fault.

Model 42PG60UD (manufactured September 2008)
Power Supply Samsung EAY41360401
Mainboard 60PG30UD-AA

I received this as a non-working set, so I don't have any insight into its history, or the circumstances of its failure. I'm in Brisbane, Australia, and there's a good chance that it has operated in above-30C temperatures for some of its life (although there are no components showing any signs of heat stress).

When AC is connected, the red LED on the power...

Hi all, long time watcher, first post. Have a LG 42PG60-UD with the dreaded clicking relay problem. I'll work through some basic troubleshooting, measure the ps voltages and take some photos before posting again. Hopefully someone can steer me in the right direction.
