Question about Mitsubishi WD-62725 62" Rear Projection HDTV-Ready Television

1 Answer

Wd-62725 Okay, so this tv orignally had the green blinking light. I changed 4 1000uF 25v capacitors on each of the FMT (format board), DM board and Power Supply. After this the tv worked for a week and then gave the error code 37: lamp or dmd fan. After following the repsir bulletin posted by Mitsubishi I found that the set would stop blinking after 60 seconds when connector FC was unplugged. The bulletin suggested replacing the FMT board, and I did just that. Well 3 days later the tv gives error code 37 again. Would the (2) 3300uF capacitors on the power board cause this to happen? That is the only thing I can think of because I'm about ready to start destroying it.

I would suspect a faulty Zener or Diode, transistor, allowing dirty DC or AC ripple, to the Caps.. use a scope and have a look. One must always find the cause of why things fail simply fixing the symptoms simply means it will fault again.

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.

Green blinking light


Have you tried the reset button on the front of the tv, on the far left I believe? That probably won't solve your issue since this has been an infamous problem for Mitsubishi.

If the reset button doesn't work the most probable fix are the (12) 1000uF capacitors (4 on each board) on the Power Supply, FMT board and the DM board. There are several other replies from reputable repair people on this site for this problem on the wd-xx525 series.

You probably just need to replace the DM capacitors. You can get the V26 DM repair kit from www.tvrepairworld.com which has the capacitors and the Cd with instructions

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

I turned on the TV but just got a black screen but could hear audio just fine. Turned the set off and unplugged it. When I plugged it back in the green timer light started flashing and would not stop...


Nonstop blinking is likely a DM or format board - format board most likely. I have rebuilt several of these by simply replacing all the caps, about 70 of them, and takes about two hours start to finish... But this set does need to boot. It takes about 70 seconds of flashing green light before you're able to press the power button - even when everthing is working as it should..
Hope this helps!

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.

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).

Wd62825 blinking green light


if you have replaced the caps on the DM and the FMT and power supply. you can unplug the e2p. the set will run without it if it is the problem, however it will take 5 to 10 minutes to boot up so be patient.
if it boots try turning it on. the picture should look terrible because no
light engine data is getting to the dm. chances are it is not the e2p, in the over 300 of these chassis i have repaired maybe 10 had a bad e2p. most likely the chassis needs to be rebuilt. check out www.tv-techs.com
