My mitsubishi tv W55613 won't turn on. green light keeps blinking even after resetting


Hit the front of the tv near the blinking light... give it a good rap or two. See if this helps. Helped mine. I had the same problem and the tech who came out to the house told me that it would work and it did! I could hardly believe it but it worked.

1 have a 6 year-old Mitsubishi model WS-48511 series 1080 rear projection TV that now won't turn on. A few days ago we shut the TV off, and now when i plug it in the blinking green power light...


This is called the blinking green light of death-----only one of two things can cause this problem.

First: remove front speaker grill (IT PULLS OFF) AND remove inspection plate behind it; look for the two bundles of wires coming down and to the right from the front keyboard of the set.

Unplug both plugs you find (different and marked so you cannot mix them up-----the idea is to take the front keyboard out of circuit-----set will still function with remote as receiver is behind front screen)

Try (after 70 seconds) to turn on with remote

If it comes on---defective reset button on front keyboard----use set only with remote or remove and remove actual reset switch---it is located behind and part of frame for screen----entire front screen would have to be removed to get at it.

Second: if disconnection of the front keyboard does not help, the DM unit is bad.

As you look from back of set it is large metal box at extreme left side.

The blinking light is the unit trying to "Boot" up-----these have a problem where caps and a few other parts in that unit fail-----kits on the net are available----Mitsubishi no longer sells or services these units but PTS Electronics does repair them.


Let me know if you have questions and try disconnection of the front keyboard FIRST.

I had the carpet replaced in my home and the tv was unplugged for a short time , when I plugged it back in the timer light is blinking green. It will not power on, it just blinks green.


Thats caused by weak DM capacitors. They discharge when the set is unplugged even briefly then they cant recharge after getting power restored. You can get the Mitsubishi DM repair kit for your model at www.tvrepairworld.com which contains the caps and the CD with repair instructions.

Open up the front, look under the right side picture tube. Look for puddle of oil on signal board. If you see this, it has bad picture tube & signal board. Not a good repair.

Unplug tv for 1 week for vacation plug tv in &green light doesnt stop flashing.never had problems ever.


Thats a common problem caused by failed capacitors on the DM board. Usually after unplugging the set the capacitors drain down then when you plug it back in the Caps wont charge and you will get the constant blinking light. You can get the DM repair kit for your model at www.tvrepairworld.com under the mitsubishi repair kit catagory. The kit contains the Capacitors and the CD with instructions for the repair.

do this press and hold device and menu button on the front of set.. this is to retrieve a to digit error code flashed by the leds. also this set neds to "boot" let the led flash for at least 70 seconds. if it continues to blink the tv failed to boot. There is service bulliteens that states capacitors in power supply can be bad. this capacitors are kinda hard to get to and rather invovled to replace

The green led light constantly blinks. I tried the reset button and green light is still blinking. I unplug the tv, waited a few days, then plugged the tv back in, the green light still blinks. I have a lot of experience with soldering. Do you have any suggestions or can send repair directions/protocol for the DM board.

Mitsubishi WS-65513 Flashing green light


Good Day, charliek1;
This a very common problem with model. Don't listen to other comments unless the use the correct replacement parts.

SYMPTOM: Power LED does not stop blinking after plug in.

CURE: replace C9B01, C9B02,C9B10, and C9B11 (1000 uFD 16V) on the DM PCB. Replace them with part # 181P734030 (680uFd 16V).

The DM Board (PCB) is located on the very left side of the TV looking from back. Caution on removing Board and note what cables you disconnect to access the Metal Shielded Board.
Good Luck, big IRISH.

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
