Picture is getting darker


Many of these DLP sets the picture gets darker right before the lamp fails.

Average life of the lamp is 2,000 hours----about 1 to 2 years of normal use.

If the lamp has not been replaced for a long time it is first suspect in this case.

Let me know if you have questions.

Screen keeps going black


It is possible but the only way to know is to try that.

Lamps have about a 2000 hour life span which works out to about 2 years for the average user.

Usually in this model just before the lamp fails the picture either comes on somewhat darker than usual or gets dark just before the picture goes out.

The set will detect lamp is not bright enough etc and blank the screen.

The lamp light (I have seen this) sometimes will not come on even if the lamp has a total failure----no picture at all.

You might also check with a local shop or someone with the same model so you can swap lamps to see what the problem is.

Let me know what happens.

Darker screen after replacing a samsung dlp lamp


DID YOU USE THE FOLLOWING LAMP
BP96-00826A (PHILIPS WRITTEN ON THE LAMP)? ALSO PLEASE CHECK THAT THE LAMP IS COMPLETELY SEATED OR IT WILL RESULT IN BRIGHTNESS ISSUES. THERE WAS ONE THAT I REPLACED THE LAMP IN AND I NOTICED THAT THE DIAL OPENING ON THE LAMP HOUSING WAS A BIT SMALL AND WOULD NOT ALLOW THE COMPLETE SEATING OF THE LAMP AND I HAD A DARK PICTURE AS A RESULT. I USED MY CORDLESS DRILL WITH THE PHILIPS HEAD STILL ATTACHED AND REAMED THE HOLE LARGER AND IT SOLVED THE PROBLEM.
HOPE THIS HELPS.

Picture getting darker over the years


It could be your Light Engine. However, I would first check a few things:

1. Make sure your Low Power/Lamp settings are adjusted so that they meet your brightness needs.

2. Make sure you used a Mitsubishi original lamp, as generics get chewed through fast and hard.

3. Try another lamp; sometimes you can get a bad one in the bunch.

All those things don't work, consider a Light Engine ($400 + for parts; $300+ for labor)

Screen goes dull at times


The dulling picture really sounds like a lamp failing. You would need the sony lamp xl-2100u
The ghost image may be easier to fix, sometimes as lcds age you will get a slight shift in a color. deep in the sony menu there is a parameter (menu-setup-imageshift) that will give you 3 levels of correction, this may solve this issue.

Picture seems to be alot darker than before. toshiba 62hm95


I just replaced a lamp in a Sony LCD projection that was just over a year old and it was bad. It was a VERY dim picture. You have a DLP but, in either case a dim or dark picture is almost always caused by the lamp.
