You have to take the TV apart. Pull the electrical chassis out and look for bad electrolytic caps on the boards. sounds like caps on the power supply board are bad. You can tell if they are bad by the fact that their tops are puffed up and they may or may not be leaking brown fluid. Compare them against the other caps on the boards and you will see how they have flat tops.
BUT before you take the TV apart you can check the error codes by pushing "menu" and "Device" at the same time and holding for about 10 seconds. The status light will blink two numbers. ex. one flash pause two flashes is 12 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

You can buy replacement caps from Mouser electronics online
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.
usually with that model when you get a 34 eror code for lamp abnormality, its directly related to the capacitors on the Power Pwb. You can get the V26 Power PWB repair kit at the following link which repairs that issue. It contains the replacement High temp capacitors with the board location numbers and PWB identification as well as the service manual on CD. Heres the link its under their repair kit ctegory. http://servicemanuals.vstore.ca/
Is it flashing a two digit code such as 34 as thats a common fault with the WD52525 V26 chassis for a lamp abnormality caused by two bad capacitors on the PWB PCB
Replace both 3300uf capacitors on the PWB thats a common cause with that model when it displays a 34 code which is lamp abnormality. if you need more information and I can psot a link where you can get the kit to repair your set with full instructions.
>>The first thing to do is a system reset using the recessed button on the front panel.
>>If that does not work, unplug the set and let it sit overnight SYSTEM RESET button with a pointed item like the end point of a paperclip 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
the capictor problem is mostly for WS models you can locate the dm model from this link http://www.fixya.com/howto/h159332-mitsubishi_dm_board_repair 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.
