Question about Mitsubishi WD-73734 73" Television
My Mitsubishi 1080p DLP big screen tv has a lot of white dots which seem to increase in number on a daily basis. Can someone help me please?
The problem is a defective part made by Texas Instruments for Mitsubishi. The good news is that Mitsubishi is being very helpful in getting this fixed. I saw estimates on the internet ranging from $1000-$2200. My television is out of warranty. I called Mitsubishi and they offered to send a repairman out to fix it. My cost was $200. Just had it fixed today and the picture is like new!

I have a 65 Mitsubishi DLP that had the white Dot constellation on my screen. The chip to repair the problem runs around $200.00 on ebay. I called 800 332 2119 Misubishi HQ, and they referred me to a local repair shop who got the chip for FREE from Mitsubishi and charged me $200.00 to clean out the optics, and install the chip. He warrantied the chip for 5 years, prorated. I have basically a new TV. This chip projects the picture, and we are getting the latest version of it. I am pretty handy, and watched him change the chip. It was pretty involved. For the price of the chip, I had a professional install it and service clean out the entire optics. My set is from 2009. Hats off to Mitsubishi for recognizing the problem and stepping up and giving us the repair component for free. Love my big Mitsubishi Screen!

The random whit dots you are seeing is more than not the DMD or million little mirrors board. The white spots represent some of the mirrors that are sticking in the on position. In that case they are always reflecting white light from the lamp. I don't concider the DMD board a do it yourself repair since on the older DLP set it requires mechanical alignment as well. The best thing to do is contact a techincian and see what they might charge to repair the TV for you. Please take a few moments to rate my answer...Thanks..

You need to replace the "light engine". This is very very difficult. You need to take it to a repair shop. But this will be very expensive. Around $1,000.00

SOURCE: We are having white dots
That means you need to replace the Optical Unit Block/Light Engine.Dmd board has been known to cause this also, but most of the companys replace Dmd and optical unit.
