Screen is a darker black on one side compared to other side

One half of my Toshiba 56" DLP is a darker black than the other. When the tv is turned on and the screen is black there is a distinct line down the middle where one side is a darker black than the other. Is this a sign of my bulb going bad??

This is a light engine problem and it is a recall for toshiba. Call them and they need to give u a new light engine.....even though u will have other problems after they do that.

I have a 56" DLP Samsung (HLR5668W) Right side goes solid black

The color wheels will never fix an issue like that. The only things that will cause that issue is a bad DMD board which is part of the light engine or the digital board which is not. Freak Squad need to replace the digital board.

Samsung 2006 56" HLR5688W DLP TV Right half of screen turns black. Left side normal picture. Corrects itself when set is turned off and back on. Randomly occurs - sometime picture is ok for half a day...

Possibly a bad light tunnel assembly if the part is only a shadow effect. If not then probably a bad DMD board. The DMD board is part of the light engine but needs to be replaced by a technician.

Fading screen

If you're seeing a shadow either vertically or at an angle the most common/probable cause is the light tunnel in the light engine. I have this same problem with my ru-44sz51d and have found many people with similar problems. For reference search "dlp light tunnel" as many samsung dlp's are suffering from the same problem and have been since they were purchased. You should be able to repair this yourself, but only if you feel comfortable and are knowledgable in such a situation. The repair may consist of replacing any number of the 4 or so mirrors or just reapplying the silicone adhesive to the original mirror. As I have not done this yet myself I can only speculate and refer to topics I've read about. Good luck

DLP TV: Left half normal, vertical 6" band center is gray, right half almost black. What's wrong?

No. The optical engine is OK. You need an adjustment in the light tunel. Call a tech to do it.
