No picture or sound?? status light flashes in four blinking intervals. I was told it could possibly be the lamp it has never been replaced.

Lamp is possible----

Mitsubishi TV troubleshooting
Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for 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 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 and Engine disconnected

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!

the power supply on that model seem to go bad after a while. the caps aren't properly reted it's power needs. they dry up. if you are good at soldering, replace c1 on the board (big cap) with a cap that has a slightly higher voltage rating. or replace the whole power supply. you might not be able to get one from nec, but you can try www.projectordoctor.com

first did you getthe lamp from miths and if notyou could have bought a bad lamp. you need to get a lamp form mits if you did not buy from them. if you did buy from mits have them replace the lamp it has a 90 day warranty. try hitting the menu and device / input buttons for 5 sec and repost the blink code. it is a 2 digits blink code. (ex. 23 or 33 or 26 like that)

Lamp is bad need new lamp

I think this sounds like my problem (need to replace the projector lamp). However, when I hit the "on" button, my SXRD 50" blinks green for about a minute then starts blinking red. Can you confirm the bulb solution? I was very pleased with this sight when my fan malfunctioned. I got the fan in a matter of day's from Sony and it fixed that problem.

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.

What are the labels on the lights? Timer/Lamp/Service and what color is wich?

This is usually caused by 1 of 2 things.

1: You have a lot of dust in the vents so the bulb gets too hot. You might see a flashing red temperature light on the front status button. Clean the vents to the light housing and see if that solves the problem. You might also want to physically disconnect the power from the TV for about 30 seconds to allow it to reset if it is just a random problem.

2: Your light is about to go out. If you have had the tv for a few years, it is possibly time to replace the light bulb. You can usually tell this because the light will be dimmer than normal and possibly all 3 indicator lights will be blinking on the status button on the front.
