Lamp never fires Unit goes right to cool/shutdown.


The ballast might have gone bad, you'll need to check the output voltage of it. In some projectors, the power supply/ballast are combined as one PCB instead of 2 separate boards.

My 73" mitsubishi dlp WD-73827 turns off and has a red status light blinking. I have replaced the bulb and the heat sensor... any answer to what else could be the problem?


It is helpful to have the sequence of the blinking red light. This may help:

MODELS: WD-52627 / 52628 / 62627 / 62628 / 62827 / 62927 / 73727 / 73827 / 73927

3. Error Code Operational Check

Note: The TV must be in "Shut Down" and not have been switched Off, to perform the Error Code Operational

Check. When the TV is switched Off, the code automatically resets to "12" No Error.



Pressing the front panel "DEVICE" and "MENU" buttons at the same time, and holding for 5 seconds,

activates the Error Code Mode. The LED flashes denoting a two digit Error Code, or indicating no problem

has occured since the last Initalization.



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.

• 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.

When I turn on my ps3 model cechg01, it blinks the green light a couple times then shuts itself off. No other color lights just the green one, then beeps three times and shuts off.. Can anybody help narrow...


When you plug in your system with the power cable and turn the toggle switch (in the back) do you see the red stand by light?

The red and yellow light comes from 1 bulb and the green and blu light comes from another..

If you have the YLOD and your yellow/red light is out, you will only see the green light.

I am really interested in your problem.

Do this to check your status: If you can do this function below but not any other, chances are, you do have the YLOD. It can be fixed.

Power off the unit using the toggle switch on the back. Hold down the 'eject' button and turn the toggle switch back from off to on. This will run a fan test and should eject your disc. Remember, this will only work on the 20, 40g models. Not the backwards compatible units with the 4 usb port holes and the memory card slots.

Status indicator flashes 3 short times, then one long red flash


Once the status light blinks 3 times, this is an indication that there's a problem with the lamp. The lamp may need a replacement.

If you replace the lamp, but get the same problem, check the inverter board.

If you're not sure where the inverter board is, then you may need to contact a pro for your safety.

Good luck and have a good evening!

DLPs have flow chart trouble shooting techniques to pinpoint exactly why your set isnt completeing the boot sequence. If you would like the service manual for your model let me know and i will post a link where you can purchase a complete one.

Tv keeps turning off?


cutta, you will most often hear a click on boot then the fans start up and lamp will then fire. The picture will start to show up....at what point does it shut off? and do you hear a click when the tv is turning off? Is it the complete tv shutting down, fans and everything that turns off? Do you see any lights on the the front panel "POWER", "STATUS" or "LAMP", what are they doing? If you see a Power, Status or Lamp light after it shuts off the below are what they mean if there is an issue. POWER - STATUS - LAMP - CONDITION/ISSUE: Off - Yellow - Off - Temp. high/dirty filter/excess room temp Off - Off - Yellow - 4000 hrs. Lamp usage warning Off - Off - Blink Yellow - Lamp Cover open Off - Blink Yellow - Off - Air Filter Cover open Off - Off - Red - Lamp failure (failed to turn On or broken) Off - Blink Red - Off - Fan Has Stopped Off - Red - Off - Circuit failure (short) or DVI cable disconnected If you want to check for the last "Error Code", after you first turn the TV on, by pressing the front panel ?DEVICE? and ?MENU? buttons at the same time and holding them for 5 seconds, it activates the Error Code Mode. The ?Power LED Light? blinks/flashes (1/2 sec delay) and then flashes again denoting a two digit Error Code indicating no problem or an error has occured since the last Initalization. i.e. "Power light" blinks 3 times (1/2 second delay) and then blinks 4 times then 1 sec delay and repeats a few times. This would mean "Error 34 - Lamp abnormality". See below for error codes..... Error Code - Description or issue 12 - No Error detected, check Power Supply 32 - Lamp Cover is open 33 - Air Filter Cover is open 34 - Lamp abnormality 36 - Light Engine (DMD or LAMP Fan stopped) 37 - Exhaust or Lamp Ballast Fan stopped 38 - Lamp temperature high 39 - DMD temperature high 41 - Short is detected 44 - DVI cable between FMT & Engine disconnected. Sorry for the long answer but it was an open ended question.
