Westinghouse TV Problem

[Bob AZ]

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
Bob AZ

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.

I think Funai made these along with the Sylvania branded LCD sets.

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.
