Question about Televison & Video
Flashes between black screen and pictureon and off upwards of 16 times before staying on picture. After extended viewing random flash to black.
A shop should look at this---my guess would be a bad main board-it is of course the most expensive board in the set and controls almost everything.

I have a picture but the tv will periodically turn itself off during the day and then flash the 3 blinking lights...anyone know what the problem could be. We can fix it ourselves if we knew for sure what it is.

check your closed caption, long time ago there were 4 cc options. Turn it completely off, that might get rid of it.

This sounds like a power supply issue. TVs operate on DC current and therefore must have a power supply board to invert AC house current to DC as well as regulate the DC current supplied. Heat is created by this process and therefore certain components on power supply boards are prone to failure due to repeated overheating. I would suspect capacitors on the power supply board are failing so they are only able to store enough power to allow the video board to work every 30 seconds and then it shuts off again. You can replace the whole board but I have repaired these before for a few dollars and some soldering.

All the troubles I've seen with this model are because of the LIFI lamp. Panasonic warrants the lamp assembly for four years from date of purchase. Call Panasonic toll free hotline or go online for an authorized warranty shop. Good luck
