Panasonic 50in TV keeps flashing up the input menu?
My Panasonic 50in TV, if left on for a few hours, starts to flash up the input menu constantly. We have to turn the TV off by the mains every night so we get a few hours of TV the next evening. If left on the TV goes bananas by scrolling through the input menu and choosing a different input itself, eg AV1 or HDMI 2 and the tv turns over.
I had the same issue with a differant brand of tv , i solved it by the following method, you may get lucky !!
Try to do a power reset first by having the TV unplugged from the power outlet for one minute, then do factory reset. Do the factory reset 3 times for a full reset to occur. Once the initial setup screen appears, go on and press the up arrow on the remote then power on the TV.
If still u/s maybe best you contact Panasonic ,here is the link ..
