I have an 8-year old Panasonic TV that I repaired recently thanks to nice people in the group. thanks again!
Now after about 2 months or so the TV started to turn itself OFF and back ON. It did this maybe once a day, then twice, now this evening did4 or 5 times.
It stays OFF for about 2 minutes, but I didn't check to see if it is 2 minutes even. I tried to reset it (unplugged everything for a day). I did not set the clock, and I turn the timer off. I don't know what else to do. I noticed that when it comes back ON it displays the menu on the screen (setup, timer, picture, etc). Also while it is OFF you cannot turn it back ON. I tried both the remote and the switch in the front, no go. It's just dead, but I think I hear some noise inside, almost like the TV would be ON without picture.
I don;t have the sound hooked up, I use it as a monitor, and the sound goes to the stere system. I should probably connect the audio straight from VCR to TV and see if the audio circuitry is also OFF or ON during this time.
Any other ideas? seems to be a "digital" effect, I don't think there is something that overheats or another "analog" defect. When it comes back ON it is 100% functional, picture is perfect.
