    When I turn the tv on with remote, the green light stays on for 3 seconds,

    then goes off. There is no picture or sound. I unplugged it and left it alone

    for a day but still same problem.

  • Anonymous May 28, 2008

    unplugged my tv to clean behind it and plugged it back in to find the green light ( reset) flashing. Did what the manual said to do, then called mitsubishi and had no results. They are willing to send out a tech at my cost. They do not stand behind their product. I would like to know how to correct this problem without a service call.

    my WS-55511 worked fine yesterday, nothing today


    I tried everything including calling Mitsubishi, but that was worthless.


    i saw the note above and after a full day of trying different things, I ran my finger across all the buttons and it started right up


    go figure, I Guess its time for a Panasonic Pasma

Ws-55511 green light changed caps. where is pico fuse located ?


There are at least two pico fuses in the DM unit along with the caps; DM is large metal box on left as you look from behind.

Blinking green light that does not stop means problem is in DM unit that is not booting up.

If you have questions let me know.

The power outage went out yesterday and my tv wont turn on


Hi,
Most likely it is capacitors on the dm board that have gone bad. This is a fairly common problem and has been addressed on fixya many times. If you know someone who is good with soldering and technically incline or even an honest electronics guy then the repair is quite cheap. If you have any other questions please let me know. if its not the capacitors on the DM supply then its a problem with the whole DM assembly that part usually is around 300$. So you may want to consider purchasing a new tv. Trying the 7 caps on the dm supply board shouldn't cost much if it takes anything more then that. I would sell the tv on craigslist or ebay and recoup as much as you can towards your next tv.
thank you,

On my WS-55511 TV, after a power interruption, will not power up. All i get is a continuos blinking green light.I tried unpluging the tv several times, no luck.


Good Day,

LED does not stop blinking after plug in. Check for 12 volts at connect or PF pin 10 and 28 volts at connector PF pin 11, (on the board on the right hand side, but on the left side of board towards the back of TV). If the supplies are correct suspect a problem in the DM Assembly (part # 955C230002). Part is not available for replacement.

Check C9B01, C9B02, C9B03, C9B13, C9B14, C9B17 and C9B18 (1000 UFD, 16V, 105C) on the DM Power PCB located within the DM Assembly. If they are bad or not, replace them all with part # 181P734030 (680 UFD, 16V, 105C).


The DM (Digital Module) Assembly is located on the extreme left of the chassis from the back. It is standing in a vertical position. Remove cover and you see the Cap’s in one corner of the inside PCB.

Good Luck, Big IRISH.

Ws-55511 replaced all 7 caps in the dm, still wont power on


I have seen this only 2 times----you may be able to unsolder and remove the reset micro switch---you have to remove the whole screen to get at it---the micro switch board may not be available---the switches can be tested with a ohmmeter set to high end and of course should not have a reading across them--I bet the reset switch is bad--you can remove it and put the keyboard back---most of the Mitsubishi sets use the same type of switches--Only other thing is leave the keyboard disconnected and just use the remote.

Glad you found the problem.

Ws-55511 DM 5volts draged down blinking led


Hello,

Did you check the caps on the DM board? They usually go bad after a period of time. Remove the DM board and the metallic cover and there should be 4 to 7 capacitors (There are different revisions of the DM board). Check these caps also, replace if needed.

Thank you,

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.

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.
