    I plugged the tv directly into the wall and unplugged everything from the back of the tv. Same result



    Is there any thing else I may easily check for this problem?

THIS IS MY STANDARD ANSWER TO THIS QUESTION==SOMETIMES PEOPLE DO NOT TRY THE EASY POSSIBLE REASON--IF YOU HAVE ANY QUESTIONS LET ME KNOW---IF THE ANSWER TOLD YOU something you did not know--rate the solution----

ONLY 1 of 2 things can cause this problem----

First thing to do is remove front speaker grill--it should pull out and is secured with plastic pegs--behind it you will find an inspection plate---

Notice the one or two pairs of wires coming from the front keyboard of the set---remove the inspection plate and follow the wires to the right--you can unplug both plugs(most have two and they are marked with letters and different sizes so you cannot get them wrong)

The idea here is to remove the front keyboard with its reset button etc from the circuit---You will still be able to try to turn the set on with the remote---

These sets have a Receiver that is called a DM board--(large metal box to the left as you look from the back) and if the power goes out the green light will blink for about 70 seconds and then go out---it is the Receiver booting up. It is called the DM board.

If disconnecting the keyboard allows the set to turn on--you have a bad reset switch and two choices---either operate the set only with the remote or to remove the front screen and get at the reset switch (it is tiny) and remove and/or replace it.

If disconnecting the keyboard does not restore the set to operation---the receiver is bad---there are 4 or more caps and some pico fuses that can fail in that unit---Mitsubishi no longer sells or repairs these--if it is bad and not the caps there is a company you can send the unit to and have it repaired--if you need to know their name let me know---

You can call them and get a quote for repairing the receiver.

Disconnect the power cord of the TV from the surge protector and connect it directly to a functional wall outlet and check if the TV is working normally. Otherwise disconnect all the cables from the TV including the power cord then press and hold the power button on the TV for 30 seconds then reconnect all the cables and check if the TV is okay.
If not then some capacitors on the power board have gone defective and needs to be replaced.

    The issue is with the main power board and requires servicing.

I have a WS-55511 rear projection TV. We had a power outage in the area and the TV will not power at all. Could this be a blown fuse?


if the green power light just blinks that is one issue==========if the green power light does not come on at all suspect a fuse----follow the power cord (set unplugged) into the set and plug in ac fuse is right there.

If you have the blinking light that will not stop it means the DM unit in the set was damaged and that is expensive.

If you need more information or have questions let me know with a comment here.

UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ON FOR A MOMENT AND GOES OFF.

PRESS AND HOLD “device” and “menu” buttons on front of tv for at least 5 seconds and then release both together.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protect the Convergence IC or IC’s is blown---set will detect no voltage to convergence IC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES AND THEN TO GET IT TO REPEAT MORE YOU HAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

Green light blinks and cant turn tv on


If this is a WS-55511, it is probably caused by a DM module. Unfortunately, it is not available nor does Mitsubishi offer a rebuild option. Mitsubishi's phone# 1-800-332-2119.
Give them a call and you never know what they may offer you.
Hope this helps,

My tv goes blank with sound only.


tough call. from your decription it could be the tubes the pulsating. but if i had it in the shop i wwould first look at the convergence curcuit. the fact that the on screen display come up in colors inidcates convergence problems. you might have multiple component falure there. as for cost it could be diddicult to say. average repairs like this barring piture tube problem at my shop run 200 labor and about 150 parts. this is just for convergence cuircit rpair

Blinking green timer light on front nearpower button keeps blinking, tv will not turn on, unplugged for 24 hours and tried again, also hit system reset and still nothing.


Thats a common problem when the caps on the DM need replacement. They will function fine untill power is interupted then the set will not complete the boot sequence when power is reapplied and the led will just continue to blink. Hers a link to the kit that will usually repair that issue the kit comes with instructions.

Press in together the menu button and the Device/input button on the set and hold them both in together for 5 seconds and see if the led will blink a two digit error code, then respond to this same post and let me know if it gave a error code and what the two digits were.
