We have a Toshiba 42HM66 DLP. It is at least 3 years old and the lamp had never been changed. Lately the picture has gotten darker and once the unit is on for awhile the picture starts flickering and colors are not right. We assumed it was the lamp. Changed the lamp and still the same problem. Called Toshiba, they could not help but said picture flickering is not a symptom of needing a new lamp.

When power supply to TV exceeds 224V the TV switch off. It then tries to switch "on" again and will do so until the power supply to TV is lower than 224V.

I have a Blaupunkt IS 70-33VT PIP TV. It has worked perfectly since 1994 and the picture and channell changing are still good, but the sound only works when the volume control is being increased.

I would really like to prove him wrong and believe I have enough ability to replace a component if I can discover which one. Any advice you can give will be greatly appreciated.
