Mitsubishi 65 DLP has two white spots on the screen. I just replaced the bulb a month ago and one spot showed up the other day and another today. What is this?

The white spots are pixels that are burned out. They will just gradually get worse. You will need a new screen or just replace the whole TV. Probably buy a new one for what it will cost to get a new screen put in it.

It probably has the same DLP chip as my Mitsubishi television. The mirrors in the chip set get stuck and create the white spots. There is no way to fix this other than replacing the DLP chip.

Bad optical light engine, most expensive part in set

Thats a very coomon problem which is caused by a failed DLP chip. The mirrors get stuck and thats what causes the white spots they will keep multiplying untill the entire screen is filled. You will need to replace the DLP chip. You can get the replacement DLP chip and illustrated instructions on how to do the repair from www.tvrepairworld.com

Replace the optical engine---the chip if you can find it is over 200 and not something real easy to replace.

Replace the DLP chip at cost between $160-$300 for the part and about two hours of your own time to do it.

Hi, I have a mitsubishi 65" DLP model # 65733 that I bought in December 2007 brand new, about six months ago I started spoting white dots on my screen that started blinking and then became permanent, thinking is was dust I cleaned everything inside with compressed air without success.
The stars multiply daily to a point that it was intolerable to watch anything with all the white stars and a few black ones that showed up.
We called mitsubishi but got no where, I was out of warranty. (they still deny having a problem with their DLP's)

I had a service tech inspect the tv and was told it could run about $800 to $1000 to replace the light engine with refurbished parts with 90 day warranties.

Researching on line I came across a DLP chip that is compatible with several mitsubishi and samsung models, so I decided to chance it, and replace just the DMD chip before we trash the tv, it was unthinkable to pay $800 to repair a tv that we could buy now for under $900.
Thanks God the "gamble" paid out and the problem got solve with just $150 DLP chip in about 15 minutes of my time.
If you are not mechanically nor electronically inclined, I recommend you use a technician for the installation, but don't let anyone tell you you need to replace the whole light engine, it is a ripoff.
If your problem is just white or black dots on the screen that do not move.......this will solve your problem!!

P.S. Hope this will help you and for the record..... "I will never buy a mitsubishi product again".

If you get White or black dots all over the screen (DMD symptom)
If you get a pixilated picture (DMD Board)

If your Mitsubishi TV has white spots in the picture , you can call Mitsubishi @ 1-800-332-2119 and request a free DLP Chip to fix the problem. They will send the New DLP Chip at no charge to a TV Tech in your area to install it for $200 flat rate. That is about a $250 savings if you had to pay for the chip . Call them with your TV's Model number and serial number and let them know when and where you bought the TV.
It saved me some hard earned money and now my TV is like New !

If you bought the set new you might just want to contact the manufacturer - if they are decent, they might just try to help you out with your dilemma.
