I have fallen to the "Blinking Green Light Death"! I have model WS-65869 and it is 9+ years old. Paid $4,200 new. Almost time to replace but don't want to at this time. Still waiting for the 3D LED TV's to get bigger and drop in price.
Anyway - I read a lot of these blogs. Most common problem is the capacitors on the DM circuit board. I found online a step by step procedures on replacing the capacitors. My DM board had 7 capacitors (some have 4) and after removing the DM board I could not see anything wrong with the capacitors.
Since these capacitors are real cheap in price I said what the heck, lets try this. The capacitors on my DM board were 1000uF, 16v, 105c. The instruction I found said to replace with 1000uF, 35v, 105c. I could not find these local. So I used 1000uF, 25v, 105c. These capacitors were a lot bigger and took a little more time to get them soldered into place. Cost for 7 capacitors $ 3.41 with tax. Approx. 6 total hours (including finding parts).
To my surprise when I was done and put everything back, my TV lives again! I want to thank everyone who helps on these forums. Keep helping, we appreciate all of you!

One point on all these sets. Mitsubishi put out a service bulletin on most of these, they recommend replacing the 1000uf with 680uf.

I have personally done them both ways, but thought I would share Mitsubishi's recommendations.

Good luck,
Jim

Default Bglod ws-55511

I have been using my 55inch HD 1080 Mitsubishi tv as a tv stand in the bedroom since I had the blinking green light of death a couple years ago. Wife said to get rid of the tv so I googled a fix and landed here. I have a buddy who is a technician and said he would resoldier new capacitors if I brought the board to him. Anyone have the instructions on how and what to remove? I tried clicking on some links in this thread but they lead to dead links.

I bought a very nice Samsumg HD as a replacement for the main room but I would love to get the Mitsubishi fixed since it had such a beautiful picture. Thanks for any help!!

Well, an update as to what I have done.

I replaced the capacitors on the FMT board (1000uf 25v), the DM board (1000uf 25v), and the power supply board (3300uf 10v, 1000uf 16v). I had some time to test my TV this morning..I still have the dreaded green light. Any thoughts as to what I should do next?

EddieZach, What is the model number of your TV?

Thanks,
Roy

I'd suggest you go down to Radio Shack & get some of the finest (thinnest diameter) high-silver content solder - perhaps with a rosin flux core.

Just my 2 cents. Someone else here may be able to provide better advice.

Well I'm currently using 0.032" diameter solder, but it may not have a rosin-core...Should get a thinner diameter? I was thinking the solder was balling up since I used too much as well as I probably need some flux...I also didn't tin my iron It's my first time doing this so I'm learning as I go...I'll probably end up redoing most of my work since I have a feeling my work is subject to why it's not powering up. As a lot of my joints have too much solder on them, can I just take off the excess and make sure there is enough solder in place? Or will I need to completely replace all the capacitors that I have done?

As for the power supply 1000uf capacitors, would it matter if I changed them to 25v instead of the usual 16v? I know you can up the voltage on the DM board as well as the FMT board but I wasn't sure about the power supply board.

I also disconnected the FMT board from the power and it still would not power up...Also, with the two fans...Aren't they both supossed to run while the TV is on and powering up? I noticed they weren't running when I tested the chassis this morning...

Hi Paul! Having the blinking light that goes for 30 seconds, then turns off and then the unit won't power up. I have the WD-62527. Worked fine last night then just won't power up today. We did have a scheduled power outage for 4 hours a couple of days ago. But, it worked fine afterward... for one day I guess. Could you please send me the PDF and any other help would be much appreciated. the_1habit @ hotmail

Default Need help

I have the WD-60735 that died 1 month after the original warranty expired. That repair cost me $450. 18 months later, it has died again. The status light blinks red and the timer light blinks green. Is this the same problem and what is the solution?

Thanks

Default Mitsubishi WD-60737

Hi all I have a Mitsubishi WD-60737 it was made in Jan 2010 so we have had it a little over a year, for the last week when we turn it on the green light will flash then the Mitsubishi blue screen will come up but that is as far as it will go, if I let it set on for 10 mins or so then unplug it and then replug it and turn it on it will work but every day I have to go thru the same procedure, any help would be great.

Default RE: Mitsubishi WS55613

Hello. I am new to this forum and have had the blinking green light problem, which I had fixed (after attempting the soldering ourselves with no luck). Tv was fixed by repair shop for $400 and we paid $500 for it from family, so we figured it was worth it. The picture was narrowed down to a horizontal line too, so that needed fixing as well.

So now, less than two years later, the set is reluctantly clicking on or not clicking on at all. Unplugging, waiting, plugging in again seems to encourage it to click on, but obviously something needs to be fixed. Wondering if I need more than the four capacitors changed.

Paul: I emailed the verizon.net address to request instructions, but it bounced back. Will pm you with my info. Thank you!

I have gotten the green blinking light of death a third time in the 9 years I have owned my 65" WS65869. My wife went out and brought home a 55" flat screen and said swap these out. So I now have removed all the electronics (except the light gun assy) and am offering them up to those that might want/need something. I will get a lot of satisfaction using my sledge on the cabinet. Any takers? Reply to my log in ID at AOL.

I have the GLOD on my WD-52725 that's a bit over 5 years old. I have just reset it whenever I've had it before, but that doesn't work anymore. Is it too late to repair at this point?
