Panasonic - TH-P50X80A - Strange problem - unresponsive & cycles input

[santoitaliano]

Hi All,

Strange issue i am experiencing, TV is used outside (covered area).

Has an issue now, when you turn it on, it can work fine for a short time, then turns un-responsive and cycles through inputs on the screen, at this time the buttons on the screen do not work, and the remote does not work, although the IR led flashes with each key press as it is meant to.

I suspected an issue with the "Key Board" not sure what it is called, but upon disconnecting to trial without it, the remote does not register at all.

Any ideas?

Thanks,

Santo

Anyone know if as the unit is outside, if there could be any form of dirt/corrosion on one of the connectors (HDMI Maybe?) That would confuse the auto-switching input logic of the unit?

sounds strongly like the keyboard on the tv is shorting out....

The button board is bad. Pull it out and replace the tact switches or the board itself.

Does anyone know if the remote control should function with the button board removed? I have tried to disconnect it but loose remote function.

I should be able to test for short on switches I will do that next.
