Now,tv on?.Tv "LAMP" LED light indication flashes or stay on?How long the Lamp been inside this tv,been inside like 1 1/2 or 2 years and tv been on each day like 4 or 5 hours a day in used.The lamp life are over.Should replace another lamp.

Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast.Here's the instructions to replace it for a samsung ,it works like your mitusibishi:http://www.fixyourdlp.com/guides/samsung/bp47-00033a.php The ballast has a sensor that detects when it's not able to power the lamp or if lamp is not responding,it will flash red when that sensor detects that.When you say: "it began to roll like the vertical and horizontal hold did not work then the sound went out" Do you mean you where getting horizontal lines? If you did that could be the Dmd.his is how it works: http://electronics.howstuffworks.com/dlp1.htm Basically the light of the lamp goes through a tunnel that carries a color wheel(rotating disc with a gamma of colors that creates the colors on your tv)then the light of the lamp goes through the DMD board which is a chip composed of around 2 million pixels that creates the images and colors.When it starts to fail it will create black bars,pixelation,color distortion or white dots on screens. Usually when there's a green light it could indicate a problem with the power supply,sometimes some capacitors do go bad. Check all of this and comment on this answer to see how it went.

It can be fixed, but the cost may surprise you. It would be cheaper to get a new TV.

Ballast Board may be Bad it is what turn Lamp on Call Encompass for parts 1-800-638-3328 or look for one on E-Bay they have good deals on Parts.Also CK Fan to Lamp it maybe defective .Call Mats for Fan 1-800-628-1118 they have lamps also.

this is a symptom of a bad lamp. for some reason it won't spit out a lamp error. shaking up the lamp will sometimes fix temporarily but you will find replacing to be the answer. if your tv has a fan error, you will get 4 red blinks.

I had the same problem. I deducted that if my TV worked fine for an hour or so and then the colors became bad (green, people's faces purple...), it must be a overheating problem. Simple logic, right? So, I picked up a few tools and a small vaccum and went to work.
I went first for the main source of heat: The lamp. Just a few screws, and I removed it. The lamp cage has a fine screen to prevent the dust to cover the lamp. Mine was covered with dust! And the fan behind the lamp was also covered with dust! Bingo!!! That's my problem! I cleaned everything and vaccumed all the air vents on the the back of the TV. I put the lamp back and checked that the fan was working. The TV works like new since!
Before you are out of a TV for days and spend an arm and a leg for a "Technician" to fix it (replacing expensive parts that didn't need to be replaced in the first place), try what I described above first. It's very simple and it takes only 15 minutes.
Since my TV is 2 1/2 years old, I purchased a replacement lamp. I know that one of these days it will burn out. I'll be ready and my TV will be working again in 15 minutes!
Since my problem was solved, I didn't go to the next step. There must be one or two other cooling fans inside the TV, but they must be working...
Good luck,

Power issues (Tv not turning on) were typically due to faulty ballast. While the TV reports a bad lamp it is the ballast itself causing the issue. Samsung is well aware and will replace both the ballast and the lamp (since the lamp can be prematurely aged but the bad ballast). After replacment most people stop having issues.

HLS4266W 43" dlp. In less than 1 yr whining grew worse, but did know what it was. Year passed with warranty and lamp went out. Replaced lamp. Worked for 3.5 hrs. Turned on next day and did not work. Got another lamp, but did not work. Figured out might be color wheel. Replaced it too. TV started up. Watched that night. Turned on next day, heard loud pop. Lamp never came on. Withdrew and reinstalled lamp a couple times to see if that worked. Did not. Currently, with new lamp and color wheel installed, lamp light blinks, but no lamp comes on. What now?

Did you have color problems in past? Most of these sets have convergence problems. Amps goes out. But you should have seen some type of distortion from color, red,blue, green. If no color problems then maybe vertical ouput out or horizontal output bad.
