I would guess that one of your timers is set to turn the TV off automatically, especially if it always turns off at the same time after it is turned on.
Your specific model of TV has a sleep timer, and two other timers. I would check them to make sure that they are all turned off. If your TV is set to turn on automatically by the timer, it will turn itself off automatically after 90 minutes.
The timers are set to "off". When the TV has been off all night, it will work for about 4 hours when turned on and then will start shutting off. In order to turn it back on, I have to unplug the TV and plug it back in to the outlet. Then it will work for about 25-30 minutes and shut down again. When I unplug/re-plug a second time, the TV will work for less time about 15-20 minutes and so on. I called a Panasonic repairman and can not get a service call for another two weeks. Any suggestions as to what could be the cause of the problem? Should I contact a non-authorized Panasonic repairman?
