    green light flashing, tv will not power on, tried unplugging for 24 hours, still flashing green light

  • bmeck2003 Dec 04, 2008

    I have a Mitsubishi WD-52725 and had to unplug it today. When I plugged it back in, the green light flashed and kept flashing. I could not turn the set on.

    I followed the instructions in the troubleshooting pages of the manual and pressed the reset button, but the green light just keeps flashing. I unplugged the set for several hours and when I plugged it in again the green light just kept flashing. Tried the reset procedure again, but the green light just keeps on flashing.



    Does anyone know what the story is with this or do I have to call Mitsubishi service?

    i have the same exact problem. Does any one know how to stop this green blinking light of death? Or how much this is going to cost to fix? Is it even worth it?

Good Day;

Cause #1 1. Red status LED, self-diagnosis error 44, check for open F9A06 on the Power PCB part # 283P128050 on the Power PCB 2. Red lamp LED, self diagnosis error 34. Check for 5-volts DC at J-9 connector pin 1 and 2 on the Engine Driver PCB if missing replace the Power PCB part # 930B921002 3. 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 4. LED stops blinking after 70 seconds of plug in but will not power on. Check for 3.2 volts DC at connector LE pin 3 and 4 on the Control PCB, if low suspect problems with the switches/buttons on the Control PCB part # 935D776001 5. LED stops blinking after 70 seconds of plug in but will not power on. Keyboard is not locked and key inputs at connector LE pin 3 and 4 check good. Suspect the E2P PCB part # 934C121001 6. (LED does not stop blinking after plug in) Disconnect the USB connector from the card reader to the front from the Chassis, if the LED stops blinking after 70 seconds replace the Card Reader part # 299P271010. 7. (LED does not stop blinking after plug in) Disconnecting the USB connector from the Card Reader did not help. Remove connector FC from the FMT PCB and plug the unit in, if the LED stops blinking after 70 seconds with FC removed suspect a problem on the FMT PCB (part # 930B924002), if the LED keeps blinking with connector FC removed suspect a problem on the DM PCB (part # 934C116002). 8. (LED does not stop blinking after plug in) On the DM PCB (part # 934C116002) check C81A2, C81A3, C81B3 and C81B4 (1000 UFD, 16V, 105C), if any are bad, replace all of them with part # 181P734030 (680 uFD, 16V, 105C). See Service Tip VS-78A 9. (LED does not stop blinking after plug in) On the FMT PCB (part # 930B924002) check C8F19, C8F21, C8F22, and C8F27 (16V 1000 UFD 105C), if any are bad, replace all of them with part # 181P734030 (680 uFD, 16V, 105C). Good Luck, big IRISH.

My tv does not come on.A green light is flashing above my timer button. No picture.


The green light flashing is an error code. Count the number of flashes and it will tell the issue. Write back once you've counted the flashes. Also, was the TV having any issues before this? Was there a recent storm or power surge?

Call MITS, and try to get a tech to assist. Green timer flashing is "waiting for CPU to boot". Normally 70 seconds after plug-in. If doesn't stop, then not booting, and you won't be able to turn on. It only boots after being unplugged.

Continuous green flashing light


ther are some bad capacitors on the dm board in this tv, but this model is not layman friendly, we usually send in the entire chassis to Mitsubishi for a rebuild this cost about $300 then there is the cost of service also, this job will probably cost around $5 or 600 dollars.
