If your HDMI input keeps changing. Do this procedure, First check the input button on the back of tv if it is stuck up. If not , check the input button of the remote if it is stuck.

I had the same problem. It has nothing to do with power supply board. Its the switch assembly board on the side of the set. Once I disconnected the board everything was fine including the remote fuctions.
Look for any loose contacts in power outlet. Try it on a different power outlet. Try changing the input device to something you are sure, works such as a DVD player.
Switch off TV manually, switch off power, remove plug and retry after 48 hours.
If problem persists, please refer it to a qualified service technician.
That tv input it is could be shorting out or it dying,if it is ramdomly switching to other inputs.Tries tv unplug,replug the tv back like about an hour later for the tv to a resetting itself.Go into the tv Menu go to PICTURES,go down to do a resetting to do a whole resetting of the tv Tuner signal board to go back to the factory setting,this problems should be solved.If not just used and connected other input ports connections on the tv.
Sounds as if your telly is switched out to Computer Input screen, that is a message to tell you that it does not detect your computer. You need to switch it back to TV
It is not picking up signal. Look on your remote for a button marked tv/video or inputs. Try to switch back to rite input or your sat or cable box has failed. Try another tv to see if you get pix

Well, the only thing that seems to be working so far is to plug AV cables into the "input 2" ports (on the front of TV). I plugged in my PS2, without turning it on. It has not switched at random since (about 30 minutes - it had been switching off and on for the past 2 hours). Anyone else have similar success?
