Re: mitsubishi WS-55513 won't turn on

From what i know thru extensive research.....and i mean alot the dm board (as in the whole thing) is not all bad its thecapacitors on the dm board that are supposably cheap O'z if you know what i mean. there should be 4 of them. you can buy the replacemnets from radio shack for about 8.50. if you know someone who is handy with a soildering iron, or a freelace electically type then ask them if they can put the new ones on for you. the correct one you need are -40 degrees to +85 degrees Celceus...tolerance +20%, now this is important 1000microfarad.... now these capacitors cant be less than 16V they can be over but not under.... typical brand to get is have to remove the dm board which is in a metal shield once the back part of the television is removed you will see it cause it looks like it should be in a computer. but apparently this is typical and its a very simple fix but everyone that is capable to fix it want to bend you over and do you should be ashamed of themselves for not correcting this themselve and offering help with cost.. hope this helps guys!

Two choices =
1) Replace DM MODULE. 650.00 is right.

2) Rebuild DM MODULE. Done right = a little less than Mits.
Caution: High degree of skill needed and ask about warranty
in either choice.Rebuilds usually cover only parts installed,
not complete module.If you do the research on repair,you
will find pin push reset does not work,in most cases....T.

Wait for the flashing green light to stop the use a pin to push the reset button next to the power and it should turn on fine. I've had this issue a couple of times when I get a power spike.

Green light flashes under timer when tv is turned on. no picture

Sounds to me that the DM is the cause. If this model is 7-8 years old, it uses a DM that is no longer available or supported by Mitsubishi. You could confirm this by calling Mitsubishi at 1800-332-2119. This is there Customer Service Line.
Hope this helps,

Mitsubishi hdtv1080 won't turn on. green timer light flashing

could be a lot of things really. when you replace the bulb, there is a switch that will prevent the tv from turning on if the cover isn't sitting correctly, by moving it that might have shifted so it would blink, but not turn on. if not, well get it serviced, sorry

Wont power up , green indactor light wont stop flashing

You have four capacitors bad on the "DM" module in the unit. I recommend you get a tech to do this repair. This is due to the complexity of accessing the DM module. A qualified tech can do this repair in under an hour. You can find a tech in your area by inputting your zip code on the home page of this website. Let me know if I can be of further assistance

Mitsubishi ws-55513 blinking power light

The infamous flashing green LED problem is usually due to a failing or faulty DM board. I purchased the PDF manual online and was able to locate and remove the components as necessary.

If you can solder, and are semi-proficient with electronics it is 4 bad capacitors on the DM board...

Otherwise there are facilities that can repair your failed board for about 275.00 or replacement of the board is between 350.00 and 500.00 buck USD.

Good Luck with your repairs....

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...

Mitsubishi flashing light replaced capasitors that were blown tv still has flashing light

The four cap replacement in DM module repair is simplistic
and incomplete, as you found out. ALL defective DM modules
have bad SMC's ( small "top hat" caps) AKA surface-mount
capacitors that can be changed only by the most highly skilled
bench techs. We used to change out hundreds years ago in
camcorder circuit board repair.DM board repair is a much more
accessible,thus more "do-able". For more info.............T.
