Re: green light blinking, tv won't turn on

Had a certified Mitsubishi repairman out on Wednesday. It was indeed the four $1.69 capacitors that needed replacing. The bill was $376.95 which included the service call to my home.

The repairman told me that prior to January '08, this was a $700 fix. Somehow I still wasn't all that excited.

If this problem is this common, the repair should be handled completly by Mitsubishi. I'm still not convinced that just replacing the defective parts assures me of a long-term fix.

I believe I've purchased my LAST Mitsubishi product of any kind. Yes, I'm bitter.

Re: green light blinking, tv won't turn on

I finally had the repairman "fix" the problem. He replaced 4 electrolytic capacitors on the DM board. Now it blinks for about 45 minutes then turns off and then a few seconds later comes back on correctly...It's still not right, but at least I can watch it. By the way, this is a design problem where the capacitors go bad from too much heat. If you write Mitsubishi Customer support and send them a copy of the repair bill they may refund all or at least some of your money....good luck.

Re: green light blinking, tv won't turn on

Have you tried unplugging your set for ten minutes and plugging it back in? Sometimes this will reset it. Also try hiolding the menu and input buttons in at the same time to see if you can enter the self diagnosis function built into the set. You should notice the light blink a two digit code. If thats unsuccesful your probaly looking at some bad capacitors in the power suppies or regulators. How are your trouble shooting skills?

SOURCE: Green blinking light on Mitsubishi WS-55813 HDTV

generally this means a bad digital module.. as a techinican the first thing that we would check are what is know as standby voltages. if they were there we would replace digital module.! question. Does it blink for more than 70 seconds. This unit comes with a lockout feature. to unlock press and hold menu down for 10 seconds on front panel.

ONLY 1 of 2 things can cause this problem----

First thing to do is remove front speaker grill--it should pull out and is secured with plastic pegs--behind it you will find an inspection plate---

Notice the one or two pairs of wires coming from the front keyboard of the set---remove the inspection plate and follow the wires to the right--you can unplug both plugs(most have two and they are marked with letters and different sizes so you cannot get them wrong)

The idea here is to remove the front keyboard with its reset button etc from the circuit---You will still be able to try to turn the set on with the remote---

These sets have a Receiver that is called a DM board--(large metal box to the left as you look from the back) and if the power goes out the green light will blink for about 70 seconds and then go out---it is the Receiver booting up. It is called the DM board.

If disconnecting the keyboard allows the set to turn on--you have a bad reset switch and two choices---either operate the set only with the remote or to remove the front screen and get at the reset switch (it is tiny) and remove and/or replace it.

If disconnecting the keyboard does not restore the set to operation---the receiver is bad---there are 4 or more caps and some pico fuses that can fail in that unit---Mitsubishi no longer sells or repairs these--if it is bad and not the caps there is a company you can send the unit to and have it repaired--if you need to know their name let me know---

You can call them and get a quote for repairing the receiver.

Let me know what more information you need--I am here to help.

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.

Green light blinking, tv won't turn on

Lamp lifetime is not 100% predictable. A lamp may fail without notice, although this is not usually the case. The picture is more likely to become noticeably dimmer as the lamp nears the end of its lifetime.

While there is nothing wrong with using a lamp until it fails, some customers may want to purchase a new lamp and replace the existing one when they notice that it is aging.

If the lamp fails in a Mitsubishi MicroDisplay TV, there will be no picture on the screen and a red front panel LED indicator will illuminate.

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.

Blinking green timer light on front nearpower button keeps blinking, tv will not turn on, unplugged for 24 hours and tried again, also hit system reset and still nothing.

Thats a common problem when the caps on the DM need replacement. They will function fine untill power is interupted then the set will not complete the boot sequence when power is reapplied and the led will just continue to blink. Hers a link to the kit that will usually repair that issue the kit comes with instructions.
