Samsung DLP Dark Picture

back light isout

how extended is that warranty, and what does it cover? Sounds to me like a classic video controller board about to fail.

Did you try going into the menu and increasing the picture brightness?

For the vibration noise, may guess would be the color wheel or one of the Fans.

As for the dark picture, it could be a bad lamp, dirty mirror or lens.

Sounds like your color wheel has gone bad.

You will need to replace the lamp. That is the only thing that will cause the picture on a DLP to go dark. Please take a few moments to rate my answer. Thanks....

Yep, fairly good chance the lamp is on its way out mate.

Did you use a generic replacement? Many TVs have a dark picture after replacing the original lamp with a generic. The other issue I've encountered are TVs that have been exposed to cigarette smoke will develop a dark, discolored picture over a relatively short time.

Good Day, tfarmer;

Since you have replaced the lamp, which is the normal cause for a dark picture. Have you checked your video settings?

The brightness level should be set at about 55 to 60%, the contrast should be set at about 90% and the video temp should be at normal or high.

If all these are set about this way, then I would think that the light engine might be going bad.

Good Luck, big IRISH.

Have you tried magic focus? if that doesn't work
replace the pcb convergence board,, It costs $96 and takes 10 minutes to replace you will have to manually line up your convergence afterward as the settings go to factory default. Everyone that owns this set has or will have to replace this part within 3 years
