"Paul, follow the trouble shooting algorithm attached to this answer. It does sound like your trouble is on the Main AV input board.

Hope this helps, good luck."

"TH - 50PF20, Power turned on (indicating green light, and a quick flash of power) But the buttons on the actual screen were locked .

We had to unlock it by pressing the volume up 4 times, then input 4 times, then press volume down 4 times and then selected Enter .

This unlocked the buttons on the TV it self and then we just selected the input."
