Mitsubishi ED-52631 does not turn on

It is possible either did not get all the dirty areas in front, and rear of set cleaned out or even that the ballast for the unit is this problem since it powers the lamp---lamp will come on and then turn off for a number of reasons.

The set does have a self diagnostic feature which usually is:

Mitsubishi TVtroubleshooting
Here's something that might also be useful. After you turn on the set, and getthe regular red blinky lights, hold down the Device and Menu buttons togetherfor about 5 seconds.
The Power light will start to flash in a two digit sequence.
For example, 3 flashes, then 7 flashes = 37.
Here are the error codes, and the corresponding problem:
12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filtercover 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 cablebetween FMT and Engine disconnected

When it shuts off and the green power light goes off, press both the menu and input buttons on the front of the set (not the remote) and hold both for about five seconds and release.

Power light will blink a two digit error code like 2 blinks and then 3 blinks and repeat it several times.

What is the error code?

Tv LED "LAMP" light indication is blinking?And ur tv projection lamp inside ur tv been used like 1 1/2 or 2 years.Yes.The tv projection lamp require changing,tv projection lamp life are ended.

You need a new projector bulb. Google up your model and buy the best warranteed one you can find. Buy a "caged assembly" and not just a bare bulb.

Then unplug your tv and get a screwdriver. Follow your model's instructions and just snug down the electrical screws. Do not overtighten them.

Then consult your manual on how to reset the lamp timer so it knows you put a new bulb in and fires up from the first try.

Treat yourself because you've just saved yourself a trip from a repairman!!

All Mitsubishi DLP Televisions have a built in Diagnostic Decoder to store the last fault in memory. This will help the Mitsubishi Technician determine what area or part defect could exsist due to your television not coming on or turning off by itself. In order to read the error code from the front panel lights, you need to know how to access this information if it is available.
Please remember not to unplug the tv from the power outlet because this will reset the error code. The television must be in the power off state or shut off state to retreive the code.
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.
Pressing the front panel “ACTIVITY” and “CHANNEL DOWN v” 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 usage.
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, then this will repeat itself for four more times before the blinking stops. If you forget the code, you can start all over again after the LEDs have stopped blinking. Just remember you are looking for a two digit code, denoted by a pause in the middle.
Example: You are watching Television and after 20 seconds it shuts off with no picture or sound. By pressing on the front panel the INPUT and MENU at the same time starts the Diagnostic Procedure, and the TIMER LED will then blink six times, and then a small pause, then six more times. This is an error code of 66, and will indicate to the Technician a defect in the lamp ignition circuitry. This will help us to order parts for the repairs without guess work.
In addition to the above code retrieval procedure- most new Mitsubishi LCD & DLP televisions have a built in Error Code Log or menu system. To access this feature the television has to be on and have a picture or blue screen to read this fault menu . To read this Error Log in the television you have to use the Mitsubishi remote control and follow this procedure: Press & release the Menu button, followed by 3564 on the remote control. You will see Lamp time, Code & Status. If an error has happened, please read the numbers indicated under Code to our service person or office staff. We can determine by these codes how to handle service on your unit.

This error code is that the light engine fan failed.

Thats a lamp abnormality, sound like the two 3300uf caps on the PWB PCB need replacing
