    Sylvania LD320SS8, same problem. TV comes on, says "DIGITAL TELEVISION" and shuts off in about 3 seconds. Does this with any outlet I've tried. This one was made November 2007.

    Guess you get what you pay for!

This particular model has a history of this problem.

This sounds like a safety feature built into the television. It may be trying to protect itself from an unsafe electrical source. The more expensive the equipment, the more sophisticated the power supply that converts the power from your outlet into your television. There could have been a lightning strike that has disabled the tv. Or it could be a faulty outlet.
Before called for a technician, I recommend plugging the television into a different outlet. use a good quality extension cord if necessary. You may find that your outlet is not polarized correctly.

Tv shuts off after 10-20 minutes

its not the problem with ur electron gun tube or with any picture ic or sound ic. Every t.v. is microcontoller switched machine.
any damage to microcontroller ic that controls the switching will lead to this kind of problem.
0.01% chance of residue EHT voltage would have affected the microcontroller.
