The WD62825 has a Digital Module located on the left side of the chassis looking at it from the rear of the set. It's housed in a metal box that can slide out of its holder after removing the trim screws.
The module has its own power supply board and there are a group of 16v/1000uf caps on that board which commonly fail causing the constant flashing standby light. Further back on the module is a small board about the size of a matchbook called the E2P module. Its SMT (Surface Mount Technology) caps also commonly fail which can cause the same symptoms. Techs can tell whether the E2P has failed by simply removing it, hooking the DM back up and trying to power the set. If it powers on the picture won't be much good - but at least you can tell what's keeping it down...
Back to the caps on the pwr board. If they've failed they usually will buldge visibly on top. And ESR is almost not necessary. In any event that's the nuts and bolts on this model.
Is it a job for a layman? Yes and no - you might strongly consider a tech if you don't feel comfortable removing all the connections that the DM has with the signal board. There are about six - multi-pin - wired connections to unplug and then sliding the DM out of the unit and carefully removing the screws and latching to take the DM top cover off...
Hope this helps.
Bill

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.

























45186c7.jpg






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

Try a reset. Start by unplugging for 1 minute, then plug back in & if still won't restart try the following. If none of the following work, you will need a technician.

Initializing the TV in many cases can remedy a problem.
In the 2006 product line Initialization is now a user function.
Pressing the front panel "INPUT' and "FORMAT"
buttons at the same time activates Initialization. When
complete all user settings will have to be set again. The

My 73" mitsubishi dlp WD-73827 turns off and has a red status light blinking. I have replaced the bulb and the heat sensor... any answer to what else could be the problem?


It is helpful to have the sequence of the blinking red light. This may help:

MODELS: WD-52627 / 52628 / 62627 / 62628 / 62827 / 62927 / 73727 / 73827 / 73927

3. Error Code Operational Check

Note: The TV must be in "Shut Down" and not have been switched Off, to perform the Error Code Operational

Check. When the TV is switched Off, the code automatically resets to "12" No Error.



Pressing the front panel "DEVICE" and "MENU" buttons at the same time, and holding for 5 seconds,

activates the Error Code Mode. The LED flashes denoting a two digit Error Code, or indicating no problem

has occured since the last Initalization.



Note: The front panel buttons must be used, NOT those on the Remote Control.



• The number of flashes indicates the value of the MSD (tens digit) of the Error Code.

• The flashing then pauses for approximately 1/2 second.

• The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.

• The Error Code is repeated a total of 5 times.



Example: If the Error Code is "23", the LED will flash two times, pause, and then flash three times.

My tv will power up with the with no sound for about 60 seconds then shuts off with grin flashing light for about 60 seconds the red light comes on amid stays on. What is the problem? The fan comes on


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power led, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating, to many popular brand TVs and other devices. Viewing it in "Mosaic" will make surf easy.

All I get is a blue welcome screen on my Mitsu WD-65C9 DLP TV. After several seconds of blue screen, it always just shuts down. I downloaded the Mitsubishi software upgrade, but it did NOT solve...


Hi Mike,

May I know if the LED light at the front panel has a pattern of flashes or flashing continuously in green color.

Please check if you can access the "Self diagnostic screen" by following the steps below.
- To activate, press the front panel "Activity" and "Channel down" buttons at the same time and hold for 5 secs. The Status led will then flash a two digit code. Example, if the error code is "23" the led light flashes 2 times(blink, blink) pause and then flash 3 times(blink, blink, blink). Let me know the error code, it will help to diagnose where the fault came from.
Note : the TV must be in shutdown not switched off, or AC power cord is removed because the code will reset to "12" means no error. Use the front panel buttons not on the remote control. If you can't access the self diagnostic, press and hold the "Activity" button on the front panel for 5 secs before entering the "self diagnostic" code.


Kind Regards,

Mjsazon

The 52525 is definitely going to either:

1. have the caps on the FMT/DM board replaced (not something I'd recommend you do yourself)

2. have the electrical chassis rebuilt (as sometimes, you can replace the caps and still have the problem).


wait time: 4-8 weeks
cost to rebuild: $400-$500
cost for labor: $200-$400
