    Thank you Slinteriors. some of the fuses on the board are VERY tiny I don't think I could attempt to test or change them, but I'll check it out along with the list of capacitors. Can you tell me how to actually test a capacitor other than visually... a meter?..

Check the power PWB pico fuse F9A09 and if thats good check the following capacitors all on the power pwb.
Power Supply
C9A52 1000uF 16V
C9A59 1000uF 16V
C9A61 1000uF 16V
C9A62 1000uF 16V
C9A39 2200uF 35V only some versions
have this cap.
C9A40 2200uF 35V
C9A37 3300uF 16V
C9A38 3300uF 16V

    You would need a ESR meter to check the capacitors, often they wont show any outward sign of being bad, they are very inexspensive I would change the ones indicated. Just test the fuse with a ohms meter for resistance.

Hello my name is Devin, I have a wd-65735 model and I just purchased it off of a friend and braught it home. He had told us from laying it on its side while bringing it home it said in the guide to let it...


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.

Mitsubishi WD 52525 lamp replaced, no picture, red light


You have to take the TV apart. Pull the electrical chassis out and look for bad electrolytic caps on the boards. The red LED probably means the 2 - 3300UF caps on the power supply board are bad. You can tell if they are bad by the fact that their tops are puffed up and they may or may not be leaking brown fluid. Compare them against the other caps on the boards and you will see how they have flat tops.

BUT before you take the TV apart you can check the error codes by pushing "menu" and "Device" at the same time and holding for about 10 seconds. The status light will blink two numbers. ex. one flash pause two flashes is 12 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

You can buy replacement caps from Mouser electronics online. There are plenty of solutions detailing how to do this already posted.

STATUS LIGHT SOLID RED ON 73 DLP MITSU MODEL WD73735


The colorwheel is your problem. To confirm this, unplug the tv, then listen thru the air vents in the back as you plug the tv in. You will probably hear a ticking sound. If you do, that is the colrwheel. If the colrwheel is working, youwill be able to hear it "spin up". It will be a sudden high pitch whine. Let me know if I can be of further assistance
