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.

Green led indicator light is off on my 62" toshiba

when you turn it off your light blinks because your internal fans are still spinning allowing the inside of the chassis to cool off, hence the reason you dont watch a DLP TV and then unplug it. DLP's are JUNK

Something died in there - perhaps a capacitor or a solid state device just blowing and cracking into pieces. happens. Open up the set and see if you can spot it around the power supply area.

I have 65 inch 1080 HD rear projection and when I

there could be two things causing this one there are caps on the dmd module that have failed
and the second is the cooling fan may not be running at start and the microprocessor looks for pulse there and that can shut it back down

Tv 62527 light goes off when after a few seconds when turned on

This is generally a Power Supply problem, usually the SMPS so it's replacement or repair.
