Hi, in the past couple of days we are noticing that whites and mostly blues in the background have a glassy or shiny flickering effect, sometimes like a window in the background or a TV monitior on a news program will have a white blotch in the middle. Is this a sign that the projection lamp is going bad. I would hate to put out the $179-$249.00 they are asking and then find out that is no the problem. Appreciate you advise. Thanks..........Don

Re: Mitsubishi 73" DLP TV (Lamp going out?)
This is definitely not a bad lamp. The lamp can only make a picture or no picture. never can cause weird video problems. I do however think i know whats wrong with your set, and it may be covered under an extended warranty from mitsubishi. if you get back to me with the model number i will assist you further.

You need a new lamp. The red light means the lamp failed to turn on.
You can find cheap ones on ebay for about $40. If you go to best buy they will charge an arm and a leg. You can change the lamp yourself and it will take less than 15 mins to do. The only tools youll need are a phillips screw driver and maybe a flat head.
Mitsubishi that the one,who u should contact.Talk to them make some kind of deal with them to help u to do a repairing or replace the tv Light Engine Projection Block.That the tv problems,this problems a design flaw on the tv Light Projection Egine Block the IC they put in that causes of this white spots are showing up will continue showing up more and more white dots.It will not stops.
Hi if your tv is a dlp it might be an issue with the DMD board Hi,Yes your problem sounds like the DMD board.This 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. Here's a video that will help you find where the DMd chip is located : http://www.youtube.com/watch?v=0jr_9A5Xd2Q Have a blessed one!
This problem is covered under the mitsubishi extended warranty for the 73" dlp. I would try contacting them to see if they will cover it. Not sure how they will handel it because you bought it second hand. If mitsubishi will not cover the repair the first thing you need to try is removing and re-seating the dvi cable between the o-block and the chassis inside the tv. mitsu claims this to solve the problem sometimes but i myself have never had it work. the only other thing to do is to replace the optical block assy. this is an expensive part. let me know if you have more questions!
