Green power light will not stop flashing and tv will not turn on or off

The green power light will not stop blinking and the tv will not turn on or off. WE have tried pushing the reset button as suggested in the manual and unplugging it from the wall. Neither have worked. TV is always plugged into APCSurgeArest and was turned off for the night. Had power failure during night. Found green timer light blinking this AM. will not stop flashing. Tried unpluging, holding menu button on front panel for 8 sec, pushed reset on front panel, holding 9 and QV buttons down on remote control--everything the manual said to do plus tried a different electrical outlet--been 8 hrs & still flashing

    I have Mitsubishi ws-55859 and I was reading about the green light blinking. Ours happened when the power went out. When it came back on the green light just stayed blinking. Can I buy the capacitors and are they the same ones for my model as the one you told for ws-55909? Sherry in Oklahoma

You need to replace the 1000uf capacitors on the DM board thats the classic symptom of the DM caps being bad the light continues to blink repeatedly. If you need more info on the repair let me know.

65 inch mitsubishi model# 65736 green light blinking


If the TV does not stay on, press the POWER button on the control panel for at least eight seconds to perform System Reset. The TV will turn off. Power on the TV and the green LED will flash quickly for about one minute. The changes you made most recently, before using SYSTEM RESET, may be lost. If this happens frequently, obtain an AC line power conditioner/surge protector.

An unusual digital signal may have been received, triggering a protection circuit. Wait for the light to stop flashing and turn TV on.

Momentary power fluctuation caused the TV to turn off to prevent damage. Wait for the green light to stop flashing and turn the TV on again

I have a Mitsubishi WD-62525 HDTV that suddenly wont turn on. Just has a green blinking light when you hit the power button. Any ideas?


I found this on another website, most likely it is your power supply capacitors.
  1. Press the "reset" button and hold for 10 seconds .... Does TV turn on and blinking green light turn to solid green.

  2. Unplug the TV from it's power source for various times, ranging between 5 minutes and 24 hours..... Does blinking green light continue upon plugging in the TV.

  3. Disconnect ALL devices from the TV; DVD, Tuner, Cable Box, unplug the TV for various duration times .... Does blinking green light continues upon plugging in the TV.

  4. Press Power and Menu buttons simultaneously and hold depressed for 20 seconds .... Does blinking green light continue to flash.

  5. Press Power and Display buttons simultaneously and hold depressed for 20 seconds .... Does blinking green light continue to flash.

  6. Insure that no front panel buttons are inadvertently stuck in an "engaged" position.

Diagnosis: If none of the above test resolve the issue, then the failure lies in one of the following:

  1. DM Module Capacitors have FAILED.
  2. DM Module is defective.
  3. EEPROM Board failure
  4. Power Supply failure.

The green light is known as "The blinking green light of death". This refers to the green LED on the front panel of the TV that normally blinks when turned on after a power failure or when unplugged: the green light is supposed to flash for about 1 minute while both microprocessors boot up: If it won't stop blinking it means that they aren't communicating w/each other. Unfortunately, it's common in Mitsubishi & other RP TV's. Getting this fixed by a professional is around $6-700 with labor, parts, etc. It's really not worth it in my opinion. I would go out and buy an LCD or an LED TV.

Flashing green light


Did you try this yet

SYSTEM RESET
If the TV will not respond to either the remote control
or the front panel controls and/or will not power Off,
press the SYSTEM RESET button with a pointed item
like the end point of a paperclip. The TV will turn Off
and the TIMER light will flash quickly for about one
minute. When the TIMER light stops flashing, you may
turn on the TV again. Changes you made the last time
the TV was On before you used the SYSTEM RESET
button may be lost, however, the changes you made
previously are not lost.
POWER/TIMER Indicator
The green light is a multi-function indicator. This light
will flash rapidly for about one minute each time the TV
is plugged into the wall electrical outlet, when power
is restored after a power failure, or using the SYSTEM
RESET button. Do not attempt to turn on the TV again
during this period. Wait for the flashing to stop and
the light to turn off, before attempting to turn the TV
on. While the TV is powered on, the light illuminates
steadily. If the TV has been programmed to turn on
automatically using the Timer feature,

Some of these sets if you unplug them---The green power light will blink for about 70 seconds before it stops--this is normal as the receiver unit in this set is booting up. Wait for the light to stop blinking and then the set should turn on. Some of these sets develop a problem where the light never stops blinking--usually the receiver is now bad--very expensive to get fixed.

I do this here for free so if this helps you give me a vote here.

Mitsubishi 55" big screen TV powers down after 70 secs We had a power outage in the neighborhood, after which our Mitsubishi 1080 HDTV WS-55909 only had a blinking green light on the front (no variation or pattern), even after the set was powered down. Upon reading online, it appeared the DM module capacitors were the likely culprit, so I sourced (7)1000 microfarad capacitors and replaced them, then reassembled the TV. This was the first time I'd soldered on a circuit board, so of course a lot of things might have gone wrong. However, after that the TV now powers up, but I only have a blue screen and cannot get the remote to work except to power the TV on and off (tried changing batteries in remote, reprogramming remote per setup manual, etc). Further, the TV powers off after 1 min and 15-20 seconds. I then tried to see if I could get any of the attached devices to work on their own with no other devices on except the TV. Each of them yielded a blue screen (X-Box, VCR/DVD recorder, Wii, cable) except the DVD player -- which displayed a great picture! The problem is the DVD will play 1 min 15 seconds then the TV will shut down and the green light will blink steadily (no pattern) for 60 seconds, then power down. And this only works if the DVD is on before the TV is turned on, and since the remote doesn't work I have to press "play" on the DVD player. The DVD is hooked to Component Input 2 so that input appears to be working fine. The VCR/DVD recorder is attached to Component Input 1. When I had it powered up and turned on the TV, I got a blue screen. However, when I left the VCR/DVD on and then turned on the DVD, there were jagged lines on the TV for 3-5 seconds, then the TV made a popping sound and shut off. When I then turned on the TV (i.e., with both the VCR/DVD and the DVD on first), the DVD worked but could not switch to the VCR/DVD without the TV turning off. I also tried switching the cabling for the DVD to Component Input 1, but the DVD no longer worked. When I tried the VCR/DVD on Component Input 2, it still only yielded a blue screen. So is Component Input 1 bad? And why would the TV work with the DVD in Component Input 2 but not the VCR/DVD? Obviously I have multiple problems here. The first one to deal with is the TV shutting off after 1.25 minutes. I am unable to see where I can get an error code when the blinking light just blinks quickly without any pattern, and neither the front panel controls nor the remote control work. Perhaps most of my inputs on the rear of the TV don't work now except Component Input 2 but I don't know how to test this. So I made a little headway with the capacitor replacements, but not sure what I can do at this point. Any suggestions? I've seen references for other Mitsubishi big screens that shut down like this, and the fix was related to the output power module, but not sure if it applies the the WS-55909. Thanks in advance for any help you can provide. estout7
