Re: Panasonic TX-P42GT20B - Stuck Stby
Well, I'm on the verge of giving in.
A new A board and a new P board, together, do not work. 10 binks. I have made sure every wire in connectors P6 and P7 work/have continuity. No other connectors are connected at all. No D board, no SC, no SS.
What does this mean? Have I been sent a defective A or P board? I don't see a way for me to find out unless I order yet another.

Well, disaster struck. The replaced A board had the exact same issue. 10 blinks. I'm thinking it surely has to be the power board.Leave a comment:

Re: Panasonic TX-P42GT20B - Stuck Stby
I've given it my best shot, according to the 2010 Viera training seminar PDF posted earlier in this thread, if the voltage between A6 pin 1 and 9 is 15v just before the TV shuts down, the problem is the A board.
My only worry is that although very similar, this PDF is for VT20T series TVs. Will this rule still apply? Shall I go for the A board replacement?

Re: Panasonic TX-P42GT20B - Stuck Stby
Hey,
Sorry to dig up this post but I've been following along with the same model, and I've had different results - and so hit a brick wall.
I tested voltages across P11 pins 1/4 and P2 pin 1 with the SC connected/disconnected, and got these results:
[B]SC Disconnected[/B]
P11 pin 4 = 15.6v
P11 pin 1 = 208v
P2 pin 1 = 209v
[B]SC Connected[/B]
P11 pin 4 = 16v
P11 pin 1 = 208v
P2 pin 1 = 208v
Also, no continuity between the Q661...Leave a comment:
