Question about Mitsubishi WS-65869 65" Rear Projection Television

3 Answers

Blinking green light stays on and TV won't turn on.

The green blinking light won't turn off and won't respond to reset or unplugging the TV. I found a possible repair for a model WS-65813 by replacing 4 capacitors on the DM Board, but the WS-65869 seems to have a totally different DM Board. Does anyone have a fix that a non-electonics expert may be able to complete?

    I have WS 65869 model, the tv will work for about five minutes, then the color will turn to black and white then picture is gone, only green screen sometimes blue screen will appear, have to turn it off manually. I tried playing a DVD, the picture looks ok for the first three minutes then it will turn green or black and white and the screen will turn to blue or green. I paid more than 4k for this TV in 2001 or 2002, with today's prices, is it worth fixing this TV or buy a new one. Can anybody have suggestions on how to fix this problem, maybe I can stretch the life of this TV. I like the picture and the sound. Thanks...Frank from San Diego

    Power failure shut down my Mitsubishi WS-65869 projection TV. On powering back up the infamous blinking green light came on and failed to respond to the Reset buttom. How can something so frequently encountered in the normal life of an electronic device cause such a comlete system failure? So, what does one do to correct this problem? Have done the Reset and unplug the TV attempt but no results. Have called Mitsubishi but they are of no help.

    Any new ideas ???

    If you have Model WS-65869, I found the DM Board in a covered box in the lower left hand side of the TV after opening the back panel. I don't remember the details of how I got it out, but I had to disconnect several wires coming out of it (be sure to make a sketch so you know where to reconnect). Once you have the box removed, just take off the cover and you should see the capacitors. I did a lousy job of replacing my capacitors, but it still worked - if it happens again, I'll probably take the board to a professional so I don't damage the board.

    Hope this helps.

    I just now paid TV technician $190.00 to tell me the DM module is not a replaceable part from Mitsubishi anymore. I paid another one $50.00 three days ago to say it coulodn't be fixed. (Should have listened to the $50 guy).

    I called the place where I bought it 6 years ago, and they said Mitsubishi will not service it because it is CRT technology, and that's old news.

    I paid $5000.00 for this TV 6 years ago, and now it's junk. No more Mitsubishi for me.

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 i plug in my tv the screen stays black and wont come on

Hi my name is Roety,
I can help you with your issue ,
Your Mittsubishi has a system the will cause the green light to blink for 70 seconds when first plugged in, if the green light never stops blinking it is either a power supply issue or a stuck keyboard button.
So do the test and reset it to see if the light stops blinking or not.

If I have helped you with your issue
If you have more questions you can still respond
I will reply asap

The timer light green blinking all the time

You most likely have some bad capacitors on the dm board, unfortunately the board is not available for this set, the complete chassis has to be sent in to Mitsubishi to be rebuilt.

Continuosly blinking green light and tv won't turn on.

Either bad capacitors -vented - on power supply board or bad E2P eprom board on DM board.Probably the capacitors-4-1000Ufd and 2-3300ufd.You should get expert help from reputable tv shop.Not really do it yourself fix either way.
