Question about Mitsubishi Televison & Video

1 Answer

My Mitsubishi DLP WD-73873 model television only powers up when I press the Menu and Input buttons simultaneously. The tv also will power up by itself occasionally. Anyone having a similar problem?

Mitsubishi thinks the power unit needs to be replaced (non-covered) The remote still works once the unit is powered on

  1. Yes, this happened to my Samsung. It was the high voltage circuit on the power power. The TV has a chip that check all the circuits on all three boards. When a circuit is low, then it won't turn on. I checked 380 volts at the capacitor connected to the high voltage transformer. It should have been at 390 volts. I took out the 100 uf rated at 450 volts, but only have two capacitors lying around: 150 uf and 220 uf rated at 400 v. I connected them in parallel make them 370 uf at 400 volts, and the TV is now working fine.

You probably have a bad lamp again I hate to say. These lamp are so critical when being moved. If after you atttempt to power on TV then red light shows, press menu+input on the front panel and hold for 5 seconds. Front timer LED will blink a 2 digit error code five times then stop. Code 34 and 66 are lamp errors, and if you read code 66 the lamp is broken. Good luck

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.

Hello,
There is a software update that is available for some Mitsubishi dlp models. The wd-65c9 is one of them. When I experienced your problem, I went to the website, downloaded the update, and installed it on my tv and boom, its fixed. It's super easy, free, and takes a few minutes.
