Hello Getoxygen,

This sounds like a DM problem. To repair this you will have to replace 4 or 7 capacitors (1000uf 35v).
Here are the instructions. Depending on your set this may differ a bit, but the central theme is getting the DM free to be worked on.

This was taken from a TV repair site used by TV technicians.

STEP 1) The DM Module loose. But itcan't be rotate out because of the upper plastic guide.

STEP2) How the DM Module is rotated out of the TV case. Allow thewires
entering the DM Module to be an axis point of the rotation.That way they barely move and don't get snagged or stretched.

WHY DOES IT KEEP TURNING OFF


Yes. Rear-proj.with 3 picture tubes. These, like most newer tvs have self-checks that shut the tv off if the fault could worsen problems for the TV (such as damage picture tubes.) or it's not able to put a picture up.
After it shuts off, you can press menu and input/device together for 5 secs, and it will flash a 2-digit code (such as "23" or "24", etc.)(vertical or horizontal error.) Though you will need to call a repair shop for repair. It's usually better if they are Mits. factory authorized, as they'll likely have more exper. on Mits.

I have a 57" mitsubishi


You probably have a bad lamp again I hate to say. These lamp are so critical when being moved. If after you atttempt to power on TV then red light shows, press menu+input on the front panel and hold for 5 seconds. Front timer LED will blink a 2 digit error code five times then stop. Code 34 and 66 are lamp errors, and if you read code 66 the lamp is broken. Good luck

How do you retieve the error codes?


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.

I turn the tv. on , the green light comes on then


When you turn it on and it shuts off---ON THE FRONT OF THE SET PRESS AND HOLD BOTH THE MENU AND INPUT(DEVICE) BUTTONS TOGETHER FOR AT LEAST 5 SECONDS AND RELEASE BOTH BUTTONS.

Power light should blink a two digit error code---for example: 2 blinks, a pause and 2 blinks--This is the most common error code.


Let me know what error code you get and I will tell you what it means and if 2-2 what the problem is.

Bad Bulb?


the pins that protrude into the lamp compartment have a tendency to get out of alignment where the lamp will only make partial contact. It sounds like what youre describing.

Without the code, you must get an original remote and press the "QV" and the "9" buttons together to unlock the TV.
