Hi,problem solved.. First you will need to open the back of the TV and locate the dry joint area inside the TV, You will need to locate where Some IC at the dry joint area that controls the display function in there, they are capacitors that are la belled Vertical lines on the panel(any IC written to vertical)...

When you locate the IC, You will need to re-solder the Capacitor. But before doing that,you can test if the capacitor is still working properly by tamping and the bottom of the IC. If the bottom of the IC has a swollen end, that means IC is GOOD,But it the bottom of the IC is flat,That means IC is BAD, Needs to be replaced...

After soldering if the problem still occurs,That means a capacitor or a resistor around the vertical line area is BAD and will need to be replaced..

After doing that,wa! la!, Your done..

Please make sure you power off the TV before attempting this instruction to avoid the risk of shock...

And also if you think you can not be able to fix it your self, please contact and expert for help...

Hi

Try for "Factory Default Reset"

- Unplug the TV and count to 10 slowly.
- Hold down the power button on the TV (not the remote.)
- Plug in the TV while holding power button.
- Count to 10 and release the power button.
- Turn it on and the TV should work now.

The problem that occurs in Mitsubishi rear-projection widescreen HDTV's, referred to as "The Blinking Green light of Death". However the green light is supposed to flash for about 1 minute while both microprocessors boot up: If it won't stop blinking it means that they aren't communicating with each other. It is suggested to replace the four (apparently inadequate) 1000uF/16 volt power supply capacitors in the "DM module" (one of the two onboard microprocessors). These capacitors are apparently undersized, in that they will eventually fail when there are voltage fluctuations in the circuit above 16 volts. It is recommended to install either 1000uF/25 volt or 1000uF/35 volt capacitors as replacements, so that they will be more than ample to handle any voltage spikes that will occur. Buy the (4) 1000uF/35 volt capacitors as replacements and take the back of the TV apart and remove the faulty DM module, then get the DM module's printed circuit board and de-solder the old capacitors and install the new ones. If you are not technically skilled enough it is suggested to seek help from a technician.

Please get back to us if you have further query else please accept the suggestion.

Thank you for contacting fixya.com

Blinking light with no picture or sound


If you have a green blinking light,
Most likely issue is with bad capacitors on the DM an FMT boards.

1) Look for bad 1000uf 16v caps on the dm board and the fmt board.

2) checked surface mount fuses (small white boxes) on DM and FMT board

Look carefully for other bad capacitors in the general area.

Start here and let me know the results.

Note, there is a lot of disassembly to get to these boards. Not a fun project.

Blinking Green light after Capacitor kit replacement WD-62725


I just repaired two Mit WD-62725 sets in the last two weeks.
The first one had bad caps on the power board and the FMT board. The scond one had bad caps on four out of the five boards.
Also, on the FMT board, there was a blown surface-mount fuse.
I advise checking all of the boards for bad caps. If you fine a bad 1000uf cap, replace all of the 1000uf's on the board.
Hop this helps,
Dan

Blinking "Timer" light for WD-62725


If this is a DLP, you may have problems on the FMT/DM boards in the sealed electrical chassis.

That's a big problem, because Mits doesn't make the DM/FMT boards available anymore. They are only available for rebuild from Mitsubishi and other qualified places.

There is a chance that there are some vented capacitors on the DM and FMT boards you might be able to replace, but it's for someone really comfortable with completely disassembling a set, soldering in 8 new caps and rebuilding the chassis.

Rebuilds will run you $400-$500 in rebuild costs and an additional $200-$400 in labor, depending on the joint.

Fast blinking green light. Won't respond to any controls, including system reset


You might have a blown capacitor on one of your boards or the other thing, it might be that the DMD board is sending irregular signals that are not being detected, and that's why there is no reaction to the commands you're sending

Blue Flickering Screen - Which Repair Kit?


yes they provide a free service manual with their kits. the symptom of the blue screen could either be the signal or the FMT as they can both cause those symptoms, My professional guess would be the signal board as the FMT will cause distortion lines across the screen with no picture.

Blinking green timer light


Check C81A2, C81A3, C81B3 and C81B4 (1000 uFD, 16V, 105C) on the DM PCB.
Check C8F19, C8F21, C8F22 and C8F27 (1000 uFD, 16V, 105C) on the FMT PCB.
If any are bad, replace all of them with part # 181P734030 (680 uFD, 16V, 105C).

Green blinking light


the PWB , FMT and DM boards all have capacitor issuses with that chassis. If the power light is blinking there are 4 1000uf capacitors on the DM that need replacing. If you need more info let me know.
