tony gregori said: Plug in the tv with the fmt fc 4 wire connector unplugged wait a min until the light stops flashing and plug the fmt back in. The fmt is the board with the FBI connector
Hi Tony - Thanks for the quick reply. Did as you recommended with the FC wire, and it worked! I got the screen to come on bright blue since I had nothing hooked up. Went thru another cycle of power off and then back on again, and it was fine.
BUT, I then unplugged the set again to re-assemble the covers over the boards, and when I plugged the TV in again (about 10 min later), I got the flashing green light again. Tried hitting and holding reset -- did not work. Unplugged tv and let is sit for 5 min and plugged it back in, and still the flashing green light. :(
The only fix is to hook a switch to the orange wire on the fmt board. This way you can turn it off when you power cycle. I did to mine and after the first time I did not have to use the switch until I lost power a few days ago. You can get a switch at radio shack for $30 plus wire to reach the front of the tv through the front input door. You can see the switch until you open the little door in front. If you find away to fix the boot problem please post back. Also everyone have a great Christmas.
To all looking for information to replace the caps:
I dont know if Larry is still here but on Dec 13th Pawpawsd posted a link for the repair.Please post back if you fix your tv

I believe the wavy lines on are startup can be corrected by resoldering the chips on the FMT board, it seems to be the same problem XBOX 360 has with the threee rings of death
If anyone can send me the service manual or the solution for the infamous timer blinking, it would greatly be appreciated. Please send the info to [email protected]
Hi, I also have the Mitsubishi WD-52525 with the blinking lamp light of death. I have replaced the lamp ($140), but that didn't work, so I'm thinking I have the same capacitance issue. I have taken this apart little by little and still can't seem to find the DM board. If you get a chance could you also send the manual for this. I would greatly appreciate it. My email is: [email protected]
Thank you.
I too have the fast green blinling light of death on my WD- 52525. It will after some many times of pluging and unpluging reset. However, I would like to fix it for good. any help would be nice. you can e-mail me at
I have a dead WD-52525 that was given to me to play with.
Sure enough, it has the notorious bas cap problem that everyone is talking about. I replaced two buldging and leaking caps on the power board (3300uf, 10V). The set still wouldn't turn on.
Then I found more bad caps. It was a set of four buldging caps (1000uF, 16V) in one of the signal board. It was the board with the thick D-connector video cable to the light engine, the most time consuming to access because it's the last one on the stack. It also burned a 4A surface mount fuse near the four caps. I replced the fuse as well. Probably the cap shorted when it failed and burned the fuse.
The caps curcuits near that area looks like some sort of power converter/stablizer that supply the board. It has these very visible toroid coil and located close to the 4-pin power supply lines. Similar circuits seems to be used in other boards.
With the caps and fuse replaced, I now can boot up the set. It responds to remote control on/off. I even get audio noise from the speaker (not real sound, just noise). But I still cannot get the light engine to turn on.
I have not yet opened and check the light engine.
BTY, I have the front video screen dismantled. Does that trigger some sort of sensor that prevents the light engine from turning on?
threre are many many bad capacitors in this set, Mitshubishi says about 100 or so get replaced when they rebuild these sets. contact them to see about the rebuilding deal.
Hello all
Larry good to hear from you. I hope you are doing better and had a great holiday.
Its been awhile and just wanted to know if anyone has found anything else with these tvs. Since I did the repair its been working ok. I have to unplug it at times to reset it. This only happens when I dont use the tv for a few days. I dont know whats up that. I have not had to use the switch at all. Just unplug it and let it startup on its own. Again that when it sits for days. This tv is now in the basement so it doesn't get used that much. Anyway just wanted to know
Could these bad caps also effect sound? I have static that I hear (not constant, but worse when the guide is on screen--and it gets louder/quieter with volume changes).
I want to thank the Techlore group on helping me fix my DLP. We ended up having 5 bad caps on the power board and a bad light. Got the new light in today and everything is now working. No more blinking light. Life is good
I am also haveing same problems I took out all 14 caps and replaced them now all I get is the flashing green light any help would be appreciated. If you could send what ever system files you have. also was wondering the biggest ribbon cable has a little kink on the edge could this cause the light to blink also thanks my email is [email protected]
Hello me again I took the wd52525 apart again and with the chasis outand heat cover off the front I can get a blue screen but now I get the "cartoonish picture people have talked about any help would be helpfull my email is [email protected] thanks for anyone who can help
I had to replace my fmt board. To fix the cartoonish problem
Also if you still have the blinking green light try booting up with the fmt fc connector unplugged
Then reconnect it after the light stops. I saw that mitsu has a software upgrade but you have to call to get it. Does anyone have a way to download it?
Hi larry I was wondering if you or anyone else has a parts manual for the wd 52525 I am trying to find the gold ribbon cable that connects the 2 boards, unless anyone has one they are not using. my email is [email protected] thanks
PS I already replaced the 4 on the fmt board along with the other 10 that usually go bad but the ribbon has a tear in it so I think it might be that

Where is located? Is it on top of the fmt board? Also check the gray wire going from the light engine to the power board. It may be cut or rubbing on the chassis. As for parts good luck. I tried when I replaced the fmt board. Had to buy a used one.
I have replaced the lamp on my WD-52725 (I know that it needed the replacement as the filament was broken on the old one). After installing the new one, replacing the cover, and resetting my set - all I get is a blinking green LED. You seem to know what the problem is - I have read on the web that it might be burned capacitors on the DM board. Do you have instructions for locating, removing, and replacing capacitors on that board?

Hope your health is improving and keep fighting. Can you or someone here please send me the repair guide for the blinking green light of death?

I have repaired the power board to no avail. Swapped the power board with another without luck. So I have all the other boards removed and its time to go on the hunt for the other dead bugs.
Hi there,
I replaced the 8 caps on DM and FMT boards, the blinking green light stop, but there is a new red light come up on Status. I tested the power supply board. I can't get power on 3.3V PA port others are find. Does anyone know what I should replace on power supply board in order to get 3.3V PA port works.
Million thanks,
Pijiu
I have as well a WD-52525 and am going to attempt to remove the DM board and check the capacitors. Can you send me any service manuals and info you have on this set please. [email protected] Thanks much!!

Thanks tony I got mine to come on without the green light but still have the cartoonish fuzzy pic, how much to replace fmt board? thanks
I found one on eBay the chassis was $30 bit had the blinking green light problem
there aare two to four caps that are bad on the fmt boardI think I will look for the pic.an e-mail address will get you the pic's if you wish!
Larry,
Can I be the 8 millionth person to ask for repair info on my TV?
I have the WD62525 with the wonderful green blinking light.

You are wonderful for helping so many people out with this info. THANK YOU!!!!
