Question about Mitsubishi WS-55513 55" Rear Projection HDTV

1 Answer

Mitsubishi WS 55809 Rear projection TV

The TV is completely dead. I have checked the fuse and it's O.K. I found the following possible fix on this site:

You will need the DM module repaired....requires replacing
four 1000mf 16v 105 degree capacitors with a bit higher
voltage = 25v or 35v.....if too tall, lay them over 90 degrees on
to board.....there are many entries concerning DM module
rebuild...........if you need further assist,let me know...T.

This may well be the fix for WS 55513, but not sure if it applies to the WS 55809 model. As a novice, I may need a little more guidance. Is their a picture or schematic that can be supplied showing me:
1. What the DM Module is?
2. Were these failed capacitors are located on the DM module board? Additionally, could I get a part number for these capacitor components?
Any assistance will be appreciated, than you gentlemen

replace DM

Picture of bad caps

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.

Constant blinking green light on Mitsubishi WS-65909 TV. Replaced the 7 Capacitors on the DM module and re-installed into the tv, plugged in and the same blinking green light problem is happening. Is

This is a V19 chassis, circa 2002

If all capacitors were replaced correctly & all caps with bulging tops were replaced, It sounds like you may have other issues on the DM pcb. Possibly defective ICs. That would be the E2P module (a small pcb which plugs directly onto the DM pcb), which is specific to your particular model & serial#

Several years ago the only way to get the E2P, was thru the manufacturer, they also, used to make a kit that you could replace those ICs yourself. Those pcbs & kits were limited. So all I can do is wish you much luck if that is the problem.

At this point I would double & triple check the replacement of your capacitors.

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
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

Hi I have a Mitsubishi ws-65615 65'' tv. I gat the green flashing light. I chainged the 4 capacitors, disconnect the front panel but still not want to work, still have the green light. ???????????????...

On the DM module where you replaced the capacitors there are three small white pico fuses. They are on the opposite site of the board. I would jumper all three by crimping a small piece of copper around them. Put the module back in place without its metal box around it. Plug the tv in and wait about two minutes. If the flashing light is off, turn it on. If this works, remove one of the jumpers. Continue until you have found the faulty fuse. Either replace or jumper the fuse permanently. When you put the DM module back in permanently, if the tv once again gives you the flashing light for more than two minutes, then the DM module is simply not setting properly into all of the pin locations.

IF the lamp has already been tried here with a known good one....then...

Most like the "DM module" needs to be replaced. This is NOT a cheap repair and Mits KNOWS these sets are a problem. There is SOME possibility that the DM module, and possibly the formatter module too--could be repaired, about a 60% chance or so, by a decent tech...IF there is one in your area that will work on these sets. If you can get someone to check it out. ....have them chack for "bad capacitors" on ALL THREE of these modules::

The DM module.
The "formatter" module
The power supply.

Often--about 10 new caps on these three modules WILL fix the set. But it is a VERY time-consuming affair, as the modules are in a BUNCH of shields and such, so...figure on 3 hours of work, perhaps the tech removing the modules--or TV--from your house, and repairing the modules, and returning. A fair price to do this.... (if you don't have a service plan...if you do...someone SHOULD be willing to come out from warranty service and do this...) IF the modules can be re-capped--would be about 450-500, depending on the trip distance and such.

if the modules cannot be repaired /about 1in 3 times...and you have a warranty..and mits cannot supply new might just get a new set. This happened a NUMBER Of times last year, where I was at.

The steady green blinking led is due to the DM not completeing the boot Cycle. You can get the repair kit at the following link which contains the replacement Capacitors and step by step detailed instructions so you can do the repair yourself. Very inexspensive Kit

Tv won't come on

I found this bit helpful (look at my comments at end):

My Mitsubishi WS-55613 (55" rear-projection HDTV) died Saturday, just when I tried to turn on the UNC/Kentucky game. It was exhibiting what I'd seen described before (found at another online HDTV forum) as what appears to be a very frequent problem that occurs in Mitsubishi rear-projection widescreen HDTV's, referred to as "The Blinking Green light of Death". This refers to the green LED on the front panel of the TV that normally blinks when turned on after a power failure or when unplugged: the green light is supposed to flash for about 1 minute while both microprocessors boot up: If it won't stop blinking it means that they aren't communicating w/each other, and you ain't got no TV to watch... frown.gif

About a year ago, I'd noticed and saved an article describing this issue, along with a repair procedure to replace the four (apparently inadequate) 1000uF/16 volt power supply capacitors in the "DM module" (one of the two onboard microprocessors). These capacitors are apparently undersized, in that they will eventually fail (usually after about 3 years) if and inevitably when there are voltage fluctuations in the circuit above 16 volts. (If you Google: "Mitsubishi + Blinking Green Light of Death", it's amazing how many other Mitsubishi rear-projection TV owners have experienced this problem.) It is recommended to install either 1000uF/25 volt or 1000uF/35 volt capacitors as replacements, so that they will be more than ample to handle any voltage spikes that will occur.

Since I have little/no experience repairing printed circuit boards, I was a bit intimidated to try this on my own, but was motivated by the one person at that forum that said he'd had to pay $600+ for the replacement DM module his set needed, along with about $150 for installation.

I went online to another HDTV forum and this time found two similar "fix" articles describing the same problem and correction, and one of these articles came complete with photos depicting the repair procedure. This led me to believe that this might actually a legit repair, as others had posted that they'd successfully repaired their TV's w/this procedure. On Sat. night I went to Radio Shack, bought the (4) 1000uF/35 volt capacitors recommended as replacements (they were out of the 1000uF/25 volt caps), and after taking the back of the TV apart and removing the faulty DM module, got my girlfriend Rene to help hold the DM module's printed circuit board while I desoldered the old capacitors and installed the new ones. (She was a remarkably patient assistant, I might add...)

Much to my dismay, after getting the TV put back together enough (I thought) to test it at about 12:30 a.m. Sunday, it would still not work, and exhibited the same "Blinking Green Light of Death". I went to bed VERY disappointed... crying.gif

Sunday morning, I set about taking it BACK apart, to see if I'd done something wrong or left something disconnected. I then realized that since I'd not installed the back cover plate for the DM module, which has (apparently critical!) grounding straps essential to the proper functioning of the DM module - the DM was not getting proper grounding. error.gif My brother, (who is an electronics tech for a local LED lighting manufacturer) came over before I reassembled the TV and also found a couple of "solder bridges" on a couple of the DM's printed circuit board components (sloppy soldering), which he feels might have also contibuted to the failure of the original power supply capacitors. I put it all back together again, plugged it in, and it fired right up! banana.gif

I went ahead and ordered a full kit online. Came with service manuals for the set and detailed pictures of how to do the repairs. Took me about 2 hours, but my Mitsubishi is up and running! contact:

Was the symptom a steady blinking green led/ If so you most likely need just the DM repair kit thats 35.00 and comes with the instructions on CD and the replacement capacitors that repairs the DM module. I can post a link for the repair kit if you would like?
