Actually you must replace the DLP chip that is buried deep in the works of the tv. Unfortunately this can run into a nice lump of change. Do what I did. Perhaps you've heard the old addage

    Sorry I wasn't done. I called Mitsubishi and complained they told me they would pay for the parts if I paid for the labor to the tune of $200.00 and they had a repair man here within two weeks and the tv is like new. That repairman did tell me though that they got in a big batch of bad chips during manufacture. And the tv's are just now starting to fail in large numbers. Hope this helps you.

    I have had my Mitsubishi for about 4 years and the guy I purchased it said I needed a lamp replaced and that's been almost a year since we purchased the bulb. I got this tv because the RCA didn't work anymore and it was brand newand I was given the Mitsubishi for the replaced of the RCA.I will call them and see what they will tell me. Thanks

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!

SOURCE: Own a Samsung DLP TV 42 inch and white dots have

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

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.

This unit uses a DLP (digital light processor) chip and if this starts to fail then you will get spots appearing on the screen. The DLP chip will need to be replaced.
