I've noticed no one has mentioned cleaning the optics and mirrors of the TV. If the TV optics become dirty this well effect the brightness. I would do a serch on the cleaning of DLP TVs. This will be the cheapest way to go.

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)

SOURCE: 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.

SOURCE: only 1/2 of my mitsubishi 62 inch dlp tv screen

Sounds like one of the light sources has failed or half of the projection source has failed(first is more likely)

If your TV is still on warranty you may want to call them to come pick it up. I doubt you'd want to move this yourself since it weighs over 100lbs

Mitsubishi dlp tv picture is getting darker


One of two possible issues:

1. Lamp is nearing end of life and may dim just before total failure.

2. A few of these models have 2 mirrors(check with Mitsubishi to see if yours is one) A large mirror in back (never gives a problem and do not try to clean it. Some idiot in these sets used a small mirror inside that the optical unit shines the picture into (wedge shaped mirror and small) and it is facing up----the fans intake air from the front of the set around this mirror--it gets coated with lots of dust---Picture can loose up to 70% of its brightness and clarity if that mirror is dirty--looks like 20 year old set .

If you do not wish to check with Mitsubishi GOOGLE THE MODEL NUMBER with "mirrors" to see.

If it has 2 mirrors I can tell you exactly how to get at it.

The color is really dim,


i have a wd62528 62" dlp hdtv that shows a picture but very dim. I have tried numerous things including factory reset and checking the lamp. I started to get a new lamp but was told if i have a dim picture getting a new lamp will do nothing. However, Mitsubishi support said that if i have a dim picture but was not continuing to get worse or darker, then they were 100% sure i just needed a new lamp. I'm confused. Will a new lamp solve my problem or no. i would just buy and try but it is very costly. please help

My 62 inch dlp tv came on and was working then with out any noise or notice the picture went to black and a steady red light came on under the word "lamp". We looked at the bulb and it does not look burned...


The tv lamp was replaced when? The tv on about 4 or 5 hours a day right?The lamp was replaced about a year or a year an a half ago?The projection lamp is dead,the life span is over.Must replaced with a new lamp.

No picture on my 62" DLP Mitsubishi


I am not sure what the problem is, but usually if a lamp is bad, the other 2 lamps will still function. Since you are getting no picture at all, I am thinking it is a circuit board problem. TV electronics are expected to last 3-5 years. After that, many components will start to go out one by one. If you have your tv repaired, I would replace the whole circuit boards instead of just the bad component. The power board is the #1 board I would replace 1st. This is the most stressed board and will cause most of your tv problems.

Mitsubishi rear projection tv color problem


I'm going to guess that this unit is a DLP projection set and that the lamp is not new. Try a new lamp. The heat of the lamp will char over time. If not the lamp, some of the internal filters in the light engine might be getting effected by heat and require replacement.

Keep us posted.

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.
