This is not something that you should attempt on your own. There are dozens of capacitors on several different circuit boards that will need replacement. Furthermore, just the disassembly process is quite complicated and time consuming, not to mention locating all the bad caps and then the re-installation process afterwards.

Mitsubishi will rebuild this chassis at their facility. Contact them so they can locate a company in your area that can handle this for you. Be aware though that this can cost $600-$700 or more between parts and labor. Perhaps someone at Mitsubishi will help pay for this repair.

How to replace the dm in wd-52525


The DM is the second board inside the Chassis block directly underneath the FMT board. But replacement DM boards if still good are very expensive your better off replacing the 4 capacitors that fail on the DM.

My lamp busted. I just replaced it but the lamp light is still bl


Thats often caused by failed capacitors on both the DM and the Power boards. You can get the mitsubishi repair kit called the V26 Chassis DM / Power repair kit from www.tvrepairworld.com which contains the parts and the CD with detailed instructions.

Hi, I have a Mitsubishi WD-52525, and have the Green Light of Death. I plan on replacing the capacitors, and have the Power Chassis out of the TV. However, I am having issues extracting the DM module...


The DM is the second board in the chassis from the right side looking in the rear. The first board is the FMT. The second is the DM, third is the Signal and the one which is sideway across the front is the Power board. The Chassis metal shields have to be removed to access the boards.

You have a bad DM Board. You need to replace it. Changing the capacitors will not cure the problem. Completely replace the entire board

Mitsubishi 52525 dlp capacitor problem red light after lamp chang


No the board youre refering to is the Power PWB which is encased inside the metal chassis block. You can get the kit that is for your model that has the capacitors and step by tep instructions on how to disassemble the chassis to accesss the Power Pwb. Heres the link to the kit you need if the lamp led is red.

Mitsubishi WD 52525 lamp replaced, no picture, red light


You have to take the TV apart. Pull the electrical chassis out and look for bad electrolytic caps on the boards. The red LED probably means the 2 - 3300UF 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. There are plenty of solutions detailing how to do this already posted.

Mitsubishi WD-52525 red light no picture or sounds, lamp has been replaced.


The hardest part is getting the chassis block out. But if youre mechanically inclined and follow the illustrations and label all the wires you unplug, its not that difficult a job. The soldering isnt very difficult as theyre just capacitors. The chassis is contained inside a metal container and has to be removed as a unit then opened up to get to the PWB PC board.
