I was told after a lot of research that there is a temp sensor for the bulb in the TV that goes bad or gets to hot due to a foam screen that's intention is to prevent dust from entering the tv getting clogged with dust.

  1. Unplug the tv
  2. locate the cooling air foam filter housing. it's in the the center of the back of the tv right in the middle of the audio video connections.
  3. depress the little tab for the filter retainer which looks just like the tab you depress to open the battery cover on your remote.
  4. remove the foam filter and clean by beating it against something or wash it and dry it thoroughly and reinstall.
  5. Then give it a shot
  6. if this doesn't work it's probably the thermal sensor for the bulb. *Note: Mitsubishi know's about this problem and will pay for a Mitsubishi factory authorized service Tech to come out and repair this problem free of charge.
  7. to find a Service center in your area call 1-800-332-2119 follow prompts just input your zip code when prompted and it will give you the service centers closest to you.

Here's an online version of your televison's (94 page) "Owner's Guide":
http://www.mitsubishi-tv.com/pdf/ownersguides/WD-60735.pdf

It sounds like the lamp in your "Mitsubishi Lamp-Cartridge" blew.

If your TV remains under warranty, you'll want to call Mitsubishi at 1-800-553-7278, and you'll need to have (a) Mitsubishi Model number, (b) serial number, (c) TV purchase date, and you'll have to ship the old lamp module back to Mitsubishi so that:
"All lamps replaced under warranty must be returned to Mitsubishi where they will be inspected for defect verification."

Return old Lamp-Cartridge to:

Mitsubishi Digital Electronics America
1001 Cherry Drive, Suite 2
Braselton, Georgia 30517

If you have trouble finding your TV's information, you need better "Warranty Management". Warranty Management can be done with software, or on paper. You may even choose to toss all your Owner's Manuals into a box, with the receipts. In case anything malfunctions/needs to be reprogrammed/reset then the manual & spare parts/cables (in a large Zip-Loc(R) baggie or two) can be quickly located and consulted.

If you television happens to be out of warranty, a nice (expensive) new lamp module can be ordered from Mitsubishi by calling 1-800-553-7278, or by ordering online at http://www.mitsuparts.com.

Refer to pages 75-76 of your Owner's Guide for complete Lamp-Cartridge module replacement instructions (with nice illustrations).

Your TV's Lamp-Cartridge part number is: Mitsubishi 915B403001

Here's an online source for the Mitsubishi 915B403001 Lamp-Cartridge:
http://www.dlplamps.com/products/mitsubishi-dlp-lamp/mitsubishi-915b403001.html?gclid=CLzb6ciaiq0CFQdN4AodZkMonA

Note that with the dlplamps.com offerings, you can purchase the lamp only for $109, or the entire lamp-cartridge module for $129. So you can save yourself $20 if you're handy. Remember to keep all fingerprints off the lamp glass element - this small amount of oil will weaken the glass, and cause premature failure of the lamp. In the event that you get a fingerprint on the lamp glass, erase it thoroughly with rubbing alcohol. Alternatively, one may prevent fingerprints with latex gloves (make sure you haven't an allergy to latex, though).

If the reason that the lamp blew turns out to have been a clogged Lamp-Cartridge Filter (once you have the Lamp-Cartridge out of the TV and in your hand, you'll be able to easily see the mesh filter), then place a regular PM (Preventative Maintenance) of this filter on your calendar.

It could be the lamp, they have an approximate 1 year life depending on conditions. If you bought the TV new, it has a 1 year warranty and labor you might want to contact warranty support. They will send you a new lamp.

To Receive a Replacement Lamp Under Warranty
Call (800) 553-7278. Please have model number, serial number, and TV purchase date available.
Important: All lamps replaced under warranty must be returned to Mitsubishi where they will be inspected for defect
verification.

Appendix C of the manual describes how to change the lamp. Handle with care (avoid fingerprints on the new lamp). Make sure the TV is off for at least an hour before starting.

I hope this helps.

You can press the "DEVICE" and "MENU" keys on the front of the TV (not the remote) and the TV should flash an error code. Here is a chart.

Error Code Probable Cause
12 No error detected
22 Recovery from momentary Reset
32 Lamp Cover open
33 Air Filter Cover open
34 Lamp abnormality
35 Chassis Fan failure
36 Exhaust (Back Cover) or Lamp Ballast Fan failure
37 Engine (DMD or Lamp) Fan failure
38 Excess Lamp Temperature
39 Excess DMD Temperature
41 Short Detected
44 DVI Cable (between Chassis and Engine) disconnected

If the code is lets say 36 the LED will flash 3 times then pause then 6 flashes.

Replaced lamp worked for a few days and now it wont power up, now when you turn it on the light blinks green and then the yellow lamp light comes on and no sound or picture.


when the set shuts down check to see what the error code is, press the input and menu buttons at the same time, hold them down for 10 seconds, the green light should blink a two digit code, if this is 38 then you have a thermal sensor problem and need to call Mitsubishi for extended warranty repair.

When I turn on the TV, nothing comes on. No pictures or sound. Red light comes on where it says lamp. Do I need to replace the lamp. Please kinldy advise . Ty


Yes. You need to replace the lamp. Mine did this when my lamp burned out.

You can try pressing <menu> and <device> at the same time, and you'll get a code flashed out to you (tens digit followed by unit digit). You'll likely see one of the following codes:
  • 34 Lamp abnormality
  • 36 Lamp Ballast or exhaust fan failed.
  • 38 Lamp temperature too high
  • 42 Lamp Fan Failed
But the user's manual and the repair manual both say that a red lamp light means your lamp isn't working (most likely it needs to be replaced).

Mitsubishi wd52525 shows error code 37


error code 37 is either the dmd fan or the lamp fan. you can see the dmd fan with the cover off. you cannot set the lamp fan as it is under the light engine. I guess the easiest thing to do is get a lamp fan 299P282010 and a dmd fan 299P283010 and change them both.

remove the back and lamp (make sure the lamp door is on) turn the tv on and look to see if the fan is running (keep you hand out of the tv when doing this - as the lamp connectors are empty) if the fan does not start - replace lamp - the connector is located under lamp housing connector JA - measure the red wire and ground (any metal part) for 12v at turn on - if 12v replace fan - if no 12v check the power pcb
