    How would I know what a power supply board looks like? You are speaking a different language to me right now. I know cars and computers but not TVs.

Hi,

I Suspect Power Supply Board.Open the TV and look for Power Supply Board. Once you find the Board, Pull out the Connectors. Take the Board out. With the help of magnifying glass, you need to check Cold Solder Joints.If not, then Check the Caps and Fuses. I imagine, if this could be due to Power Shut Off, you would be able to Find Some Bulged / Swelled / Leaked Caps. You would smell Ammonia kind of odor. You need to pull them out. Order the same Caps online or go to Radio Shack. It would cost you few bucks, in fact less than 20 bucks. Once you get the Caps, solder them and it is all set.

Note - You need to take all the Precautions as this would involve Voltage.

Let me know, if problem persists so that we could further troubleshoot.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Hi
It is probably a power supply problem associated with standby circuit. If this circuit is bad the set hardly comes on and fails. This is a task for a technician to trace the fault through the whole power supply.

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.

When the tv shuts done does the power light blink? If so what number does it blink? That will tell me which circuit your problem is in. Notice the number of blinks then let me know. Also what is the model number of your set.
