Do you have excessive drive lines on screen before it shuts off?
If so then you need to adjust the screen controls to your Tubes.

Older-model Toshiba TV shuts off by itself


There is a large sand filled resistor on the main board close to where the power cord attaches that cracks. This will stop power until it cools enough to make the connection then heats up rapidly to open it again. It may be worth the trouble if you're handy with a soldering gun and can get the back off the TV. If not then I'd consider getting a flat screen.

Panasonic TC-P42X1 acts like it is turning on, the screen turns black, then the tv shuts itself off and back on again.


Rule out any loose contacts in power outlet, RC Jack, cables and connectors. The problem described by you calls for opening the back cover and further investigation, which should only be done by a qualified service technician.

Does it blink a certain amount of blinks pause a second or just blink constantly with no pauses? Let me know it will blink a code if its going into protected shutdown. And it will blink constantly for another reason.
