Question about Panasonic Viera TH-42PZ80U Plasma TV
Plug unit in and fans turns on but screen doesn't then the red led light goes though a loop of two blinks and pauses then two blinks. Where can I get a diagnostics list for led signals.
If your model is the TH42PZ80U 2 blinks is indicating to replace the D Board (Logic) That model used two different versions D board. www.tvcircuitboards.com has both versions and can assist with determining which version your model uses.

Five blinks - AKB
circuit (automatic kine bias), the timer/standby indicator blinks
for about 30 seconds then goes to the self-diagnosis function.
Something is wrong with the video. Check video out, Q705, 732, 761
and other components on the C board, also check Q218, 219, 220 on
the A board. In addition, unit could be in IK blanking, try turning
up screen A2 slightly.
