DM is no longer available from Mitsubishi.

Unit can be removed and sent our for repair----


PTS ELECTRONICS---you will find them on the web and you can call or email for a quote.

Usually there are some caps and or fuses that fail in the DM unit.

Did you try to disconnect front keyboard to make sure it is not the problem?

If this told you something you did not know rate this solution as very helpful as I do this for free.

Location of the dm module in my mitsubishi 60111 tv


Your model doesnt have a DM module like the later versions. You have the V20A chassis and that doesnt have a DM assembly.

Mitsubishi WD-52725 DLP DM board


The DM boards for that chassis are almost impossible to find if they are still good. Have you tried replacing the caps on the DM board that you have? Thats usually whats wrong are bad caps.

We lost power the other night. Now I have a continuous green blinking light and it won't turn on. I have tried everything the manual says.


Try Going To The Mitsubishi Web Site. Downloading The Mitsubishi Service Manuals If You Don't Already Have It. It Will recommend The parts You Need To ordering. Circuit board photos are also shown which provide a visual reference during the repair process.

If you decide to have a service technician do the repair, insist that the "DM" module is removed from the TV and ONLY the four 1000uF, 16V Capacitors (Caps) located on the DM Module are replaced. MOST techincians will INSIST on replacing the entire DM Module and not simply the capacitors. The cost is about $200 for a technician to replace the capacitors and $1000 for replacement of the DM Module. As you will read below, doing the repair yourself will cost less than $4.00 for the 4 Caps.

I've been told I need a DM module by a tv repair service who checked continuity in many of the components. What do I really need to fix it/ Can I order the parts myself? From whom? Can I install them?


The service manual is available from www.partstore.com
It is part number Part# 3828VD0222B for $2.95
Hopefully the entire DM Module would not need replacing. Hopefully just capacitors in the DM module need replacing and if that is the case part store has these in stock. Their phone number is 866-925-7278

Replaced the bulb and now it wont work, the green light on front just flashes


You most likely will need a new DM module and some capacitors in the power supply. If the DM module is not happy it does this blinking thing. I have repaired a few of these DM's myself which is cheaper than the whole module. Try to find a shop that is familiar with this problem.

Mitsubishi ws-55613 green light blings rapidly and TV will not come on.


The DM module has bad capacitors in it and these will need to be replaced, or the DM module replaced.(about 85% of the time, the caps WILL fix them though...) A good shop should be able to rebulid your module for about 300-400 in the home.

DM Module


You have to take the top piece on the left side off w/4 screws. Then there are 2 things that is holding the DM unit in place on the top of it and bottom of it. Take the top one off. This will allow you to remove the DM box. Use like a tackle box or something to hold it up while repairing it. There are some screws that hold the main board in place in the front of it those will need to be removed to allow you to move it out a little.

The DM board is the one with the digital connectors on the back panel. If you already have it appart, you may as well check the caps on all of the boards. The caps that go bad are typically Jamicon brand caps in 1000 uF and 330 uF values. There are also a couple of 3300 uF caps in the PS that cause problems.
