Westinghouse TV Problem
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 |

If LCD, have you checked the backlights? 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? |

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. Arfa |

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. Ca****cher LCD / plasma, check power supply caps. Failing that, if LCD, try unplugging the backlight inverter.
