Flat screen Westinghouse TV. No model number yet. About 32" model.
Less than 2 years old. Sound OK. Picture for only 5 seconds or so then
no picture until turned off and then on again and picture again lasts
about 5 seconds. And on and on. Just started this a few days ago. No
problems until now.

Worth some time to try to fix or just dump and go on?

Where to buy a sevice manual if they still sell such things?

Thanks

Fla screen *CRT* or LCD/Plasma?

If LCD, have you checked the backlights?

LCD / plasma, check power supply caps. Failing that, if LCD, try unplugging
the backlight inverter. Many TVs will run happily with a (faulty) inverter
disconnected, but obviously, you won't actually see a picture, unless you
shine a strong light at the screen at an angle. You will, however, normally
still hear sound, which proves that the set is staying on ok.

Agree on the faulty power supply caps. I also had a Korea made TV. Remove
the main board and examine cap solder joints for overheating or caps that
show discoloration. IIRC the caps are often physically close to
transformers.
