DM Board WS48511 Green Blinking Light

I have a WS48511 with the green blinking light - no power problem. I read your article regarding the DM Board repair dated 7/12/07 and downloaded the service manual from The graphic in the service manual shows 7 capacitors not 4 in your article. Do I replace all seven with the same Panasonic 10,000 hour high temp capacitors (part number: P13119-ND )? You can email me at Thanks.

Re: DM Board WS48511 Green Blinking Light

If you do not already know where your problem is then Check for 12 volts DC (AC-off detect) at pin 3 of PC9A21, if missing replace PC9A21 part # 268P058020 on the Power PCB. LED does not blink at plug in. Check for 5-volts DC at connector RF pin 3 (system reset) if low or missing suspect the reset switch S7L20 part # 432P089010 on the Control PCB. LED stops blinking after 70 seconds of plug in but will not power on. This model is equipped with a keyboard lock feature; this can be mistaken as a no power condition. To unlock the keyboard press and hold the "menu" button on the front panel for 10 seconds . LED stops blinking after 70 seconds of plug in but will not power on. Check for 4.7 volts DC at connector RF pin 4 and 5 on the Signal PCB if low suspect problems with the switches/buttons on the Control PCB part # 935D587002 5. LED stops blinking after 70 seconds of plug in but will not power on. Keyboard is not locked and key inputs at connector RF pin 4 and 5 check good suspect the E2P PCB part # 935C978002 . Also if you can do a self diagnosis test by pressing the device and menu for 5 sec on panel of set and read the error codes.

Mitsubishi green blinking light of death

Hi Jim,

Green blinking light of death on Mitsubishi DLP TV means that the DM failed to booted up. I would advice you to replaced the 7 1000uf electrolytic capacitor on the DM board. Most of the time it fixed the symptoms. Please inquire at if they have an available DM repair kit for V36 chassis (WD-57733 chassis).

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.
