Question about Mitsubishi WD-62525 62" Rear Projection HDTV
I have a wd52825 with a green blinking light that dont go off. I can not get the tv to turn on no more becouse of the green blinking light. The tv worked great and after haveing to unplug it to move it or a power outage it just keeps blinking now. At first I could unpluge and plug it in again and after doing that for a while it would work again but now the braker went in my apartment and am not able to get the tv to work again( just the blinking lght). I have been reading about the DM board being bad and the caps on it. I have the chassie all apart and I looked at all the caps and the only one I see that is puffed is one on the signal board. I am hoping someone could help me with this problem as I have spent alot of time reading on this problem and dont know what else to do. Please help and thanks Paul
You cannot tell what capacitors are bad just by looking at them. Some can fail without any outward signs. You need a special meter to test them.

The DM is the second board in the chassis from the right side looking in the rear. The first board is the FMT. The second is the DM, third is the Signal and the one which is sideway across the front is the Power board. The Chassis metal shields have to be removed to access the boards.

SOURCE: wd62825 blinking green light
I am also a member of the WD-62725 blinking green light club. I replaced all twelve of the caps I found with higher rated ones and the blinking light problem did not go away completely but I could get the TV synced in 5 or less cycles...for a while. I finally put the TV on an UPS and it did pretty good for about a year until, for some reason, my wife muting the TV would send it into a blue screen and then the dreaded blinking green light of death. I had collected a lot of forum notes and bought the manual (virtually useless) and remembered a post where a guy put a switch on the orange power wire going to the "board to the right of the DM board," as he described it. This was the last attempt for me so I tried it. The board's name is the FMT PWB and on his WD-62825 and my WD-62725 it is the right most board, looking from the rear. Coming off of the top of the board towards the back of the set is a 4 wire connector with one of the wires being orange. Cut that wire and splice 12" long extensions to each leg. Reassemble the TV with these two new wires hanging out the back. Solder an on off switch to these leads. I used and old PC power switch because it had large "On" and "Off" labels on it. I then screwed it to a hole in back with a 1" stand off. Its not pretty but functional. Now turn your new switch off and plug the set in. If it behaves like mine it will blink green for about a minute and then go off. Now turn the new switch to the on position and you are ready to turn on your set. I hope this helps. If it does give me some feedback at rocky_beech(at)yahoo.com. I only need mine to last two more years and my house will be paid for and then I will get the best I can afford. I hope they still have plasmas by then. Cheers

Green blinking light of death on Mitsubishi DLP TV means that the DM failed to booted up. I would advice you to replaced the 7 1000uf electrolytic capacitor on the DM board. Most of the time it fixed the symptoms. Please inquire at tvrepairworld.com if they have an available DM repair kit for V36 chassis (WD-57733 chassis).

Testimonial: "Thanks, I just ordered 10 of the caps online. I work as an electronics tech on an army base. I'll pull the board and fix it at lunch. Thanks for your response. It will save me some time. Jim"
