Re: Panasonic 55vt30 board replacement

I have the same 2011 guide, except specifically for the GT30/VT30 series. It also had me check Vsus and Vda resistances on the P board, which were both over the threshold 1K (actually, I couldn't consistently replicate the Vsus reading, half the time the multimeter would simply display 1, which to my understanding is still not indicative of a short).

I isolated the SU/SD board, and the TV still gave me 7 blinks, but it "sounded" better, if that makes any sense. Before there would try to turn on, there would be a loud...

Still, if I don't get the 7 blink error immediately, I guess that will be a good sign and I will try just replacing the SU/SD board (sd board is like $30, why not).

Panasonic themselves were no help, suggesting that I should provide an estimate from an authorized Panasonic repair shop ($150), and they will give me 10% off another Panasonic TV (but...
