Our Panasonic Plasma went out after a lighting strike to the building. It was on a surge protector but still will not turn on now. Nothing. No blinking LEDs or anything. I have power going in to the TV by metering the power cable coming from the wall. So did a little researched and changed out the power supply circuit board which did not fix it. I tried to replace the transformer between the power cord and the power supply circuit and that didn't do anything. Any other suggestions.

Hello,

Unfortunately it seems that the logic board is fried (it is the most sensible part of any TV). And, if you use an external antenna the TV tuner is damaged also...

If that is it. I can not find anyone that carries a TNPH0911 1A Suffix AC..

I found a service manual and it says that the logic board (the "A" board) is TXN/A1PMUUS and is located in the lower right area of the chassis.

EDIT: please read the service manual; in case of the logic board exchange, you must do some other procedures.
