Re: won't power up

This model has had problems with the keyboard buttons on the front panel,causing them not to work and canceling out the remote operation. To verify this,you need to remove the front panel so you can access the connector on the keyboard pc board and unplug the connector.After doing this,see if the remote control is able to turn on the tv (wait for it to power up because with the connector off, the green power light will be disconnected and will not light up when the tv is on) If the tv works, than you will need to change the ten individual switches on the board - part# 432P089010 (or just use the remote only)

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 have a mitsubishi model WS-55511. The green light keeps blinking. Have reset by unpluging and then pluging back in and holding the reset but for 5 seconds and press the power button. worked once, but...

TWO possible reasons for the blinking light:

1. The DM unit (caps and or fuses) are bad---no longer made and only (to my knowledge) PTS electronics repairs/rebuilds them.

2. Less likely but Possible: remove front speaker grill and inspection plate behind it----locate the two bundles of wires from front keyboard on set and follow them down and to the right---unplug both plugs and plug set in and wait 70 plus seconds and try to turn set on with Mitsubishi remote.

The blinking light is the DM trying to boot up--if set works with front keyboard unplugged---the tiny reset switch on it is bad.

If set does NOT work that way DM UNIT IS BAD.

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.

My Mitsu Ws48511 green light blinks for about 2 minutes then stops. After another minute, it begins to blink again. It continues this until I unplug the tv. Then it often blinks for up to 8 hours before...

First: the blinking green light means the set has a DM unit in it. It should when unplugged and plugged back in blink for 70 seconds and then go out.

One of two things is wrong here:

1) The DM unit (large metal box on the left as you look from the back) has several capacitors and fuses that can fail.

2) Try this: Pull front speaker grill off: held on with plastic pegs.

Remove the inspection plate you will find in back of it.

Note the two groups of wires that come from the front keyboard; follow them down and to the right and unplug the two plugs you find; most have two and they are different sizes and marked so you cannot get them wrong.

The idea here is to disconnect the entire front keyboard and the reset switch from the set.

You can still turn the set on with the remote.

If the set now works--you have two choices----use the set with a remote and the keyboard not connected.

Remove the entire screen assembly and remove and or replace the reset switch.

IF DISCONNECTING THE KEY BOARD DOES NOT CURE IT--the Dm unit is bad---either change the four caps--lots of sites sell kits for this OR send the entire DM unit out for repair/rebuild to someone like PTS ELECTRONICS.

Blinking is a trouble code. Try unpluging for a longer time then hold power button in when pluging back in to try and reset.

Mitsubishi WS-65613 tv green power light keeps blinking tv will not turn on

Unplug the unit for 5 minutes then plug it again. Turn it on. If it does not power up, press the SYSTEM RESET button on the front panel with a pointed object such as the point of a pencil or end tip of a paper clip. The green LED light will flash quickly for about a minute then stops. You may turn on the TV then. The changes you made most recently, before using
SYSTEM RESET, may be lost. Changes you made previously, however, are not lost.

Green light on front rapidly blinks after power outage. No picture, or can't turn on

This unit, when first plugged in or after power interuption takes 70 to 90 seconds for the digital module to boot up. During the time the LED blinks green and the set will not respond to anything. After the appropriate amount of time the blinking should stop and the set should operate normally. If the blinking never stops then you have to have the Digital Module repaired.

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

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.
