Dim Mitsubishi WD-60737

Our lamp in our WD-60737 was blown so we had to order a new bulb to put inside the tv. After we ordered the bulb and put it in the picture was way brighter that it ever was. I turned up the brightness and also changed the picture mode but is still too dark. What is the cause of this and can I fix it?

SOURCE: picture on my mitsubishi wd 60737 is dark. i have increased the brightness but picture looks like a night time scene

A few things occur to me, if Lamp not recently replaced (2year average life) it may be nearing the end of its life.

Just a few models (not sure if this is one) use two mirrors where most just have one large mirror.

If the issue was gradual you may have the two mirror set, one tiny mirror at bottom of screen area points up and reflects the image into the large mirror in the back of the set which puts it on the screen to view.

If your model has the two mirrors the little one will be coated with dust and such and cuts brightness up to 70%

You can call Mitsubishi and ask if your model has two mirrors or one, if Two mirrors and they will not tell you how to get at them I can.

Let me know if you need more help.

SOURCE: Mitsubishi WD-62527 replacement lamp install and brightness low

as i previously posted, my picture was dim, muddy looking after replacing lamp with osram lamp. i fixed mine by taking the screen off and cleaning the small mirror. it had a thick layer of dust on it, cleaned with a microfiber cloth. no water, no glass cleaners. i also used a very fine new small paint brush and dusted the projector lens which also had a dust film. brightness, contrast and clarity returned!

SOURCE: Mitsubishi WD-62527. Dark picture.

That unit is a two mirror set. Meaning the light engine lens shines down onto a small mirror and that is reflected onto a large mirror and then onto the screen. Gravity being what it is dust and other contaminants cover the lower mirror. Moving the set would only aggrevate dust settling on it. To fix the problem the screen must be removed and the mirror cleaned. You won't believe the difference. It will be like watching a new tv.

SOURCE: Screen is dim. Have brightness turned up to max

Yes... from the moment the lamp is put into service, it begins to deminish in brightness. You should order a replacement lamp to have on hand.

WD 60737 error code 12 what do i need to do. We replaced bulb and now it just flashes red

Error code 12 is no problem found. I would make sure I had the right bulb, make sure it is seated properly, and make sure the door to the lamp box is on correctly. If that doesn't work, and you still have the old bulb, put it back in. Even if it doesn't work it will display a bad bulb code and not the current one if your new bulb is incompatible. Sometimes that happens when you get a new bulb with incompatible specs.

Mitsubishi wd-60737 won't turn on just flashes red I get error code 12

Hm Code 12 is "no error". Which is odd since you have an error.

However, since the age of the TV is around 7 years, you may have the problem that the power supply is known for. The capacitors in the power supply fail.

To be safe, check the lamp and make sure its in good order. May want to change it anyway if its more than a year or 2.

Wd-60737 mitsubishi blinking yellow status light ?

Mitsubishi TV troubleshooting
Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.
For example, 3 flashes, then 7 flashes = 37.
Here are the error codes, and the corresponding problem:
12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filter cover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cable between FMT and Engine disconnected

Do I need to order the housing with the lamp after burn-out?

you can order just the bulb then install that in your housing. Being careful not to touch the new bulb with your bare hands as the oils from your finger tips will cause the lamp to fail prematurely.
