The contrast setting may be misadjusted.

Even if you replace the capacitors already mentioned in this
thread, you may still suffer from the Green LED of Death. Here is how Bronson279 helped me resolve the
problem. But note that it involves
adding a switch to your tv set and requires a bit of soldering ability and the
willingness to void your warranty. BUT
you can save big $$$$ on sending the set out for repair.

Here is my solution-
After replacing several bad capacitors (you can get replacement capacitors
from Mouser electronics on line by the way.. be sure to order the same capacitance
values and same or higher voltage rating and be sure they are rated for 105
degrees C.) I still had the dreaded G.L.O.D. Note that the first time I plugged it in
after taking it apart the G.L.O.D was not there and it powered up
normally. But when I had to unplug the
set to fully re assemble it, it came back.




The issue is caused by both the FMT board (formatter) and
the DM (Digital Module) board’s microprocessors tying to establish
communications with each other. Somehow a race condition gets started with each
thinking that the other board needs to be reset and then starting the boot
process over again.





You need to interrupt this cycle with a switch. Buy a DPDT switch from radio shack (or Mouser
Elec…) and again take apart your electrical chassis (If you have it apart
replacing bad caps you might as well add the switch or you may end up having to
disassemble the whole thing again.) On
the FMT board along the top edge near the input connector side of the chassis
there is a four wire connector labeled “FC”.
It has two black wires and 1 orange and one Brown wire. Leave the black wires connected and cut the orange and brown ones about an
inch from the connector. Solder four 12
inch wires onto the ends (one on the source side brown, source side orange and
one on the connector side brown and connector side orange) use heat shrink tubing to cover the solder
connection points. (If you can’t get tubing, then electrical tape will do, but
make sure the joints can’t short out to each other or the electrical chassis.) Now take the brown and orange wires from the
connector side and solder those to the middle two terminals of the DPDT switch
(one on each side not both to both terminals) Then pick one side of the outside
terminals of the switch and solder the source side brown and orange wires to
the terminal across from the same color (brown across from brown and orange
across from orange) See the diagram below.
The idea is to connect the wires normally when the switch is closed and
break the connection when the switch is thrown the other way. Before soldering
the wires to the switch add a piece of heat shrink tubing to wire so that you
can cover the solder point up after it is assembled.

Now re-assemble the electrical chassis and route the switch/wires
outside the chassis (I snipped a hole along the edge of the top fan shield to
get the wires out.) and put it back in the TV.
You need to also get the switch to the outside of the TV somehow (I
drilled a ½ inch hole in the plastic cover to snake the switch through but you
can do it however you like)





Here is how to use it-
From a fresh plug in- throw the switch to the OPEN position (the wires
are not connected) plug in the TV, the green LED should stop blinking after 60
secs like it is supposed to. Once it stops, flip the switch the other way so
the wires are connecting. Hit the power
button. The TV should turn on- your done!
Yeah!

From a plugged in, hmmm my power must have gone out,
state. Assuming you have the GLOD, flip
the switch to the open position, hit the reset button on the front of the tv,
wait for the blinking to stop, flip the switch back closed and turn the TV on
normally… Again you are done…

Note that the first time you turn on the TV you may have to
flip the switch the other way (if the TV won’t turn on even without a blinking
LED) This means that the switch was open and you need to have it closed to get
it to work. If you tried turning on the
TV with the switch open, start over by following the reset button procedure
above.

Note this is much easier to do than it sounds. Also note that it helps if you have the
repair manual. Its titled V26 Repair
Manual –full This is nice to have
because it has a wiring interconnect diagram also which details all the
connector placements

usually changing the aspect ratio will do it .

The ballast for the bulb is the culprit. That is the circuit board directly wired to the bulb. You can get a replacement on line at:

how are you hooking it up.are you using hdmi on both ends? computer and tv? if you are using an aadapter then you will have to have additional audio cables, as the adapters dont carry the audio

Seems to be the inverter board that controls the bulbs! With the TV on if you shine a torch at the screen can you see a faint picture? If so it is the inverter board that needs replacing!

Yes, there are three. The chassis fan, the exhaust fan and the fan for DMD.
The chassis fan is going to be mounted behind an intake air filter on the right side of the cabinet from the rear view. I am providing you the service manual.

i unplugged the tv , turned the lamp switch to off . I left it unplugged for a few hours . I then plugged the tv back in , hit the reset button , located on the front bottom left . I waited for the timer light to stop blinking , then turned the lamp switch to the on position . I turned the power on to the tv . i heard the fan kick on , this time there was not a dragging sound . the screen lit up and i have not had a problem since yesterday . i think that the problem started because the tv had been left on for too long , I know that what i have done is only a temperary fix . but as long as I dont forget to turn the tv off , i should not have a problem

Dead pixels can not be repaired.
The model# WD-52525 you provided is for a DLP TV.
If you are seeing white dots on the screen it is due to a bad DMD chip or light engine. Unfortunately, it is not a cheap fix.

Good luck

Hi Terrence
Probably bad connections in the lamp base.
Heat damaged or corroded or Over temperature sensor tripped.
When it goes out next, Bump it or Tap it to see if its mechanical contact problem. That will help diagnose where the problem is
Good Luck

The lamp housing has some screws you need to loosen, did you do that?

What does the TV do when you try to turn it on?

Did you put the lamp door back on before you tried to turn the set on?

Mitsubishi... | Answered on Apr 18, 2014 | 43 views


Right next to the other controls on the TV, it is recessed so you will need a paper clip or ball point pen to press it.

The monitor link is not a standard DVI connection, it was used to connect a Mitsubishi HD set top box. You can connect your cable DVR using component video cables and get HD that way, up to 1080i but not 1080p

You might want to try a One for All remote and use its code search function to find the code you need. If you do not have instructions, you may be able to obtain them from the One for All site

The pop was a high voltage arc of electricity that blew some vital components on the main circuit board. The unit is of no use now. Repairs are far more than replacing the TV.
