Vizio 42" Plasma - P42HDTV10A - Turns on but can't change input

[Ritalin]

So I picked up a dead Vizio, changed out the caps on the power supply and got it working, but now i can't change any of the inputs/menu/channels either from the remote or the side controls.

Thoughts as to which board is bad?

Re-seated the connector to the button board? Or, it could be a stuck button on the button board causing the TV to ignore remote control input.

Does it switch on and off from the remote?

No it does not...

Leaning towards replacing the logic board.

I would try the switch board first, just in case, it is usually cheaper too.

Tuner board?

No, the board with the buttons on it. Is it separate?

No, they are separate. I'm going to try and detaching it and seeing if the remote works then to see if it's that board that's bad.
