Hi - first check that all the fans are rotating - the set will shut down if they are not.
***** WARNING potentially FATAL voltages (up to 400V DC) exist on the PSU boards - if you don't know exactly what you are doing don't ! *******
Unfortunatly the fault could be on a) PSU b) CPU board, as this monitors the PSU voltages and will shut down the set if the measured voltages are wrong c) plasma drive circuits - if these are drawing excessive current, or someother fault exists the fault feedback signal to the CPU board will activate and the set will again shut off.
Check the PSU voltages, the standby power must be OK otherwise the set wouldn't work at all !. The +5V switches on first followed by the +70V and +170V (about 1-2 secs delay.)

If the 70 and 170 dont come up try removing (with the power DISCONNECTED) the two large double row connectors on the PSU board near the 70/170 V test points - these supply the plasma drive circuits - the set will still switch off as there is a fault feedback line from the drivers, but it should stay on long enough to check the voltages.

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.

Please help with tv! green blinking light wont stop and tv wont turn on


Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.
