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
