Sounds like an issue with the DM pcb. most likely some small electrolytic capacitors. you will need to remove DM pcb & take cover off. look for capacitors with bulging tops. note the values & location & replace all capacitors with bulging tops.

Blinking Green Light on Mitsubishi Projection TV


Continuous blinking green LED on Mitsubishi's Projection which normally blinks after a power surge means that the microprocessors inside the unit are unable to communicate with each other. Usually Mitsubishi's Projection TV use 1000uF/16 in the DM MODULE (which is one of the two microprocessors), as these capacitors are too small for the load they get they usually fail usually after about 3-5 years.

They might also fail due to voltage fluctuations. To resolve this issue these capacitors should be replaced with 1000uF/25 volt or 1000uF/35 volt capacitors, so that they can handle any voltage spikes that will occur. To do the repair you’ll need to take the back off the TV apart in order to remove the faulty DM module and need to desolder the old capacitors on DM board and install new ones. All this is only recommended to be done by someone who has electrical expertise.

Thats a very common problem caused by weak caps on the DM board when power is lost they drain and then cannot recharge when the power is restored the WS55511 DM repair kit from www.tvrepairworld.com will usually solve that issue. The kit contains the caps and the cd with instructions.

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.

they are located inside the DM modules case( Metal Case on far left side ) open the metal case and you will see 7 caps on the DM power board. I am posting a pic of the board with the 7 caps that need replacement use 1000UF 25V caps to replace the 1000UF 16V caps that are currently installed.

Green blinking light following a power outage


I rebuild the DM power supply in these sets with about a 50% success rate. Sometimes changing the 7 1000uf caps on the small power supply in the DM will fix it, you'll also have to solder the small 8 pin ICs as well. Do this carefully as you do not want an accidental bridge. If this does not fix your problem, replace the DM-POWER board not the DM Assembly. It's about a 300 dollar difference. You'll need a mitsubishi authorized service center to order the part for you. Goodluck.

Flashing power light tv wont come on mitsubishi 1080


If the tv has the continuous flashing led, you have a DM board problem. It is likely bad capacitors in the DM module.. there are 4 of them 1000uf caps that will go bad. They will get a bulging top on them when they go bad. . Mits recommends replacing them with 680uf caps with a comprable or higher voltage rating. The DM module in on the left side of the set (viewed from the back) and is somewhat difficult to remove.

Mitsubishi ws-55513 green flashing light issue


I would asssume that the four cap replacement you're referring too is in the power supply of the DM module. (The large silver looking box on the left looking at the back of the TV)..
You can unplug that module from the signal board and remove it. Open the cover and you should find 4 16v caps in the power supply. If they look buldged chances are they are the failure. If not you might want to take an ESR meter to them to confirm they're okay and move on... In the back of that module is a small vertical board called the E2P module. Unplug it from the DM and plug the DM back into the signal board. If it powers up your picture might not be in the best alignment but you've identified the problem - just replace the E2P module.
If none of this works you're going to start getting into some greater technical requirements - but let's cover that when you get that far...
