Somehow--the lamp is not firing. Before you go get another bulb--check ALL of your work, and make SURE no connectors to the ballast have been left off or pinched somehow. It is easy to do this. Also, make sure the lamp door switch is making proper contact with the tab on the lamp door. You have already fixed a real problem with this set--do NOT give up so easily now!! ALso--make sure all fans are running. If ANY do not run--it WILL shut down. ANd make sure the color wheel connector has not come loose or been damaged somehow (this will be between the engine and the lamp area--likely have a "hump " raised in the light tunnel betwen the lamp and the engine--this is where the CW is). Even IF the ballast died (NOT likely at all), you can find one on ebay for under 100---and this set IS WORTH the repair. You will NOT be satisfied with some crappy flat-panel as a replacement.

SOURCE: I have a Mitsubishi WD-62525.

the status light blinking red means a fan (the unit hs 4 of them) has failed. you need to determine which one. use the self diagnostic function:
Error Code Operational Check
The TV must be in “Shut Down” and not manually switched Off, to perform the Error Code Operational
Check. When the TV is switched Off, the code automatically resets to “12” No Error.
Press the front panel “DEVICE” and “MENU” buttons at the same time, and hold for 5 seconds to
activate the Error Code Operational Check. The LED will then flash denoting a two digit Code.
Note: The front panel buttons must be used, NOT those on the Remote Control.
• The number of flashes indicates the value of the MSD (tens digit) of the Error Code.
• The flashing then pauses for approximately 1/2 second.
• The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.
Example: If the Error Code is “32”, the LED will flash three times, pause, and then flash two times.
• The Error Code is repeated a total of 5 times.

and read the code.
35= Chassis Fan failure
36 =Exhaust (Back Cover) or Lamp Ballast Fan failure
37= Engine (DMD or Lamp) Fan failure

The lamp is either defective, not connected properly to the wiring or plugs (careful alignment required on the two connections), wrong type bulb, or the front panel is not replaced properly to trigger the panel sense switch (lower right side of panel)

SOURCE: Blinking Green light after Capacitor kit replacement WD-62725

I just repaired two Mit WD-62725 sets in the last two weeks.
The first one had bad caps on the power board and the FMT board. The scond one had bad caps on four out of the five boards.
Also, on the FMT board, there was a blown surface-mount fuse.
I advise checking all of the boards for bad caps. If you fine a bad 1000uf cap, replace all of the 1000uf's on the board.
Hop this helps,

Installed dmd chip for a mitsubishi wd-60c9 DLP and got the 66 error code instead of fixing the white dot issue

Hello. I have done a lot of DMD chip replacements. I don't have access to the service manual at the moment, but the only thing that could cause an error code is to leave something disconnected. Did you check the color wheel connections on the lens side of the DMD board? The flat cable and the power connector might cause that error code. Good luck!

Mmitsubishi wd-73733 dlp green light flashing

This may help you if the set has the tiny recessed reset button on the front, those buttons (not the button itself but the tiny push switch under or behind it) do fail and trigger the set into the blinking green light of death--lots of techs call that.

Somewhere behind the speaker grill is a access plate, removed you will see the bundle of wires that come from the front keyboard---there will be a inline plug----Disconnect it.

Turn set on with remote--if it works the micro switch for the recessed reset button (its a joke as all it does is reboot the digital board) is bad---the remote will still work as the receiver is inside the screen unit. Leave it disconnected if the set works OR spend a few hours getting at the defective micro switch and remove it.

If the switch is bad they only sell (if its available any more) the whole pc board with all the controls on it.

White dots on my mitsubishi WD-73734 tv screen

Your tv is a DLP projection one. In it the image is generated by projecting light on a chip that is covered in tiny mirrors that reflect more or less the light towards the screen. In your case some of those tiny mirrors are no longer controlled - they are immobile and reflect fully the light so you get a white spot on the screen.
The DMD chip that holds the mirrors is dying and you will have to replace it. This is the only place i could find that claims to have it on stock. You can also go thru Ebay, in there you will find second-hand ones extracted from defective tv's.
It's installation is strictly a job for a person with great tv repair experience - too many thins can go wrong in there if the job is not done properly.

Getting more white dots daily. I'm told it's the DLP chip. I have model WD73734 . Can't seem to find anywhere to buy a new chip. Any suggestions?

I have little white dots showing up on my screen the size of pin holes. I just replaced the bulb 2 months ago.

You need a new dlp chip. The tiny Micro mirrors inside of it are getting stuck and there is no way of freeing them. You can either buy a new light engine which is very expensive or buy a new DLP chip and change it yourself. It takes about 30 minutes to do and is very easy. I have the DLP chip for $225 new. Other places will charge you about $345.
