Okay, so I have a WD-62525 Mitsubishi that had the Blinking Green Light of Death error after a recent Thunderstorm. I performed the capacitor fix on the DM board and replaced the 4 capacitors, all went well and the TV is back together and the blinking green light is out.
Now there are no abnormal error codes (when using the Menu+Device method Code = 12), however I have no sound, no picture and from what I can tell, I can't switch devices or anything either. The remote does turn the TV on and off though.
Anyone have a similar problem after performing the DM fix? Or anyone have any ideas on what the new problem might be?
Thanks in advance!
Wow, no suggestions...
bumping... :)
I have the same exact problem. Afyter replacing the caps and putting a switch at the FC connector of the FMT board the GBLOD is gone but now I have no video and audio. I am going to try measuring the voltage outputs from the PS board next.
Good luck and let me know how things go. I ended up calling Sears and the repair guy came last weekend. He did seem pretty knowledgeable so that was good.
He tested a few different voltages and came to the conclusion that my PWB was for sure malfunctioning and most likely my motherboard as well, although he couldn't be sure about the motherboard because of the bad PWB. His theory as to why I was getting no error messages was that the TV could not actually reach the point in the boot up process that would perform the error handling, which kind of makes sense.
He said I might be able to have someone troubleshoot it down to specific bad components on the boards but Sears didn't do that ... they just replace the boars. Total cost for PWB (~350) + MB (~450) + Labor (100) = approx $900.
My TV is back together for now but I might take it apart again to see if I can determine which components are bad. If you figure something out, let us know.
Thanks and Good Luck!
NTG: I had the same issue with my WD-52725. Replaced all the bad caps and put it back together only to find the light still blinking. I tried one more "fix" suggested by someone on another forum (that he actually got from here, lol) and it ended up working. This is the fix:
"I had the rapid green blinking light which I could not get to reset. Tore the unit apart and found 11 swollen 1000uF caps on 4 boards (FMT, DM, Power, Termninal 2). Replaced the 11 caps and re-connected boards/cables in the TV, but still had the blinking green lighs.
I then pulled the 4-wire FC connectore off the FMT board and plugged the TV to AC outlet. After 1 minute the green blinking light went out and I re-connected the FC connector back on the FMT board. Was able to turn on the TV and my inputs (cable coax, DTV input, components) were all working. I can turn the TV on/off/on using the remote or from the TV front panel.
If I lose power to the TV (i.e. unplug it from AC), the continous green light problem comes back and I have to do the trick with the FC connector again.
As suggested by earlier Techlore postings, I cut the Orange wire (6VS line) on the FC connector and spliced in a small on/off toggle switch with about 3 feet of wire. Routed the toggle switch and wire to the front of the TV and taped it behind the gray speaker grill. The toggle switch was small enough to lay flat behind the front grill.
So far the TV has been working great as long as there is no power interruptions. Should I experience a power glitch and the blinking green light reoccurs, my steps to get the TV back up is:
- Turn AC off
- Pull grill off and set toggle swith to off
- Turn AC on and wait 1 minute for green blinking light stop
- Set toggle switch to on and place grill back on the TV
- Turn on TV with remote or from front panel"
Whoa, thanks for that information. I read about that FC switch but didn't think that it applied to my problems. Looks like I am going to open her back up again sooner than later and give this a shot thought.
Thanks again, I'll update this again once I've installed that FC switch and looked over all the other caps on the other boards as well.
Hope it works for you. Just make sure you have the filter in place on the side of the TV (even with the backpanel off, otherwise the TV won't turn on at all) and connect all the other connections and fans when you give it a try. You'll need access to that FC connector so you won't be able to put the TV together before trying it, but still need to complete all the circuits of course. (You probably know all this lol) Good luck! :)
I have a WD-62525 , blinking green light keep on . I replaced the 4 capacitors , but still blinking green light can not turn off. can you help me. my E-Mail is [email protected]
