I have a Mitsubishi WD-52631. Picture will not come on. You hear the fan kick on and a whistling sound for a few seconds and then it powers off. After it shut down I pressed the INPUT and MENU buttons together and held them down and the LED flashed 6 time twice. What does that mean?

Mitsubishi rear projection DLP keeps turning off and shutting down. The red light then turns on for a while and then turns off. TV can be turned on again and works fine until a random shutdown occurs again. No fault codes are stored. No blink codes. No airflow warning messages. The original thermal sensor was replaced 8-1/2 years ago. Fans are completely clean and running smoothly. I fixed this problem by replacing the 8.5-year-old thermal sensor. The problem is gone. Mitsubishi thermal sensor part number 299P313010A. Manufacturer part number YS11A95B-C6. Do not use the connector plug. Strip the wires, and hard wire and solder the 2 connections. This might also apply to these models: WD-52631, WD-57731, WD-57732, WD-65732, WD-57831, WD-65831, WD-Y57, WD-Y65

Remove the lamp and do a visual inspection.
If this is a DLP you may have a bad color wheel! whistling sound is a sign of color wheel.

Good luck to you

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

Hi, have you replaced the lamp after 2-3 yrs of usage? The lamps used by mitsubishi tend to last around 4000 hrs 1-3 yrs.It is common for the green light to light up.Other common failures are the ballast which is the board that powers the lamp.Also check if its not overheatin, dust out the fans.Heres where u can get the lamp or ballast http://www.discount-merchant.com/SearchResults.asp?Search=wd-52631

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.

No,probally a capacitor the help the power supply board to work or other boards to work is blown.Call some tv shops get a best quotes prices,get a tv tech out to it fix,if ur tv is out of warrenty.

CK all of your Fans if they are dirty clean them.I know on samsung models that would be the color wheel.

Probably a bad lamp. This is the first thing I would try....especially if the lamp has not been re[placed in awhile.

probably your lamp has gone out, does the lamp light light?

unplug it from the wall, wait 30 seconds, then plug it back in. i had the same problem and this simple solution worked for me. Good Luck!!!!
