Yes, apparently fuse is blow off. You need to take off back cover of TV and follow AC cord to reach on power supply board.
Get service manual from Manual Zone for small fee, if you need detailed technical info and schematics of TV.

Wd-62725 tv was turning on but after a few it would tunr off to the point that now it does not. the power button does not light up


Indicates clogged filters or dust clogged fans. Clean and vacuum cooling fans and filters. Replace lamp assembly with new lamp. Should work fine. Also, try unplugging TV, wait ten minutes and plug it back in. The controller will reboot which may alleviate the problem. Regards.

Caveat: I am not a tech, I just read through the Mitsubishi service manual, and have worked on different model TV that I have owned (older model of this one) I am a little unclear on the second set of lights but I think the combination *may* indicate that the lamp fan is not starting (there are two fans though), if the blinking red is the status light. It is possible the connector for that got jostled during the trip, something fell into it from being on the side (wire or loose something) and is blocking it from spinning now, or a module unseated a bit,and is loose, or the lamp is no longer seated correctly (though the lamp light does not appear to be on) or none of these. :) These are just guesses.
Be careful if you open it up, due to potential for shock. Wear gloves, and power it down first (then unplug). Reseat any fan connectors.

Google: I used "wd-65735 status lights" to find a service pdf , it's for V39 chassis (several models)

From page 24 of Service Manual :

3. Error Code Operational Check Note: The TV must be in "Shut Down" and not have been switched Off, to perform the Error Code Opera- tional Check. When the TV is switched Off, the code automatically resets to "12" No Error.
Pressing the front panel "INPUT" and "MENU" buttons at the same time, and holding for 5 seconds, activates the Error Code Mode. The "TIMER LED" flashes denoting a two digit Error Code, or indicating no problem has occurred since the last Initialization.
Note: The front panel buttons must be used, NOT those on the Remote Control.

  • Theflashingthenpausesforapproximately1/2second.
  • TheLEDthenflashesindicatingthevalueoftheLSD(onesdigit)oftheErrorCode.
  • The Error Code is repeated a total of 5 times. Example: If the Error Code is "23", the LED will flash two times, pause, and then flash three times.

WD-62725, no picture, no sound from power on. Red status light blinks 1 then 3 blinks, Using device and menu buttons error code indicates 37 (DMD fan Failure). What can I do to correct this problem?


Hi,

Your power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

Good luck in solving the problem...

You can press the "DEVICE" and "MENU" keys on the front of the TV (not the remote) and the TV should flash an error code. Here is a chart.

Error Code Probable Cause
12 No error detected
22 Recovery from momentary Reset
32 Lamp Cover open
33 Air Filter Cover open
34 Lamp abnormality
35 Chassis Fan failure
36 Exhaust (Back Cover) or Lamp Ballast Fan failure
37 Engine (DMD or Lamp) Fan failure
38 Excess Lamp Temperature
39 Excess DMD Temperature
41 Short Detected
44 DVI Cable (between Chassis and Engine) disconnected

If the code is lets say 36 the LED will flash 3 times then pause then 6 flashes.
