MITSUBISHI WS55907 Diamond 1080 TV bought in 2000 was powered off, unplugged, for a year. Turned the set on with remote last night and worked fine, had very crisp picture.


Your TV was waiting between 2000 and now to suffer power supply failure. It is very frustrating to go from everything working perfectly to nothing.

Tv gets light blueand stays that way...comes back to perfect color the back to blue X-RAy looking it is a samsung pcl545r


Behind the screen, there are three color tubes: Red Green and Blue.

Unfortunately, rear projection screens often have these problems and the tubes do go out after extended use.

Take the television to a TV Repair shop to have this fixed. But in the long run, this may end up costing you a lot more than if you would purchase a new TV. The light tubes are fairly expensive.

No video on a 50H82 Toshiba Projection


If the screen is lit, then there is high voltage. If there is no video, and the screen is lit, then there is a loss of video. The fault can be anywhere along the main video path before it gets decoded in to the red, blue, and green compositions.

If the screen is not lit, most likely there is a high voltage failure, or there is a failure in the bias supply for the tubes.

When there is a loss of high voltage, this can be from any of the components in the high voltage area. Some of the main things that go defective are the flyback, high voltage multiplier, and various other small components.

Have you considered to replace the set with a good Plama or LCD set? This repair may end up being on the expensive side.
