My mitsubishi 65in tv has a lot of small white dots on the screen what causes this?

LCD's are bad, warranty won't fit just a few, only a lot, yours aren't enough for warranty, best get new tv, they are expensive to fix

DLP chip needs replaced...about $200 for the chip and replace yourself. YouTube has videos on how to replace

This could be something on the lens or mirrors. you can open one or both porthole covers on the left or right side of TV to determine if this is the cause. You can look at the mirrors & lens to determine if a bug or dust has gotten on either part. Then clean.

HOWEVER, the most likely cause is the DLP chip. this causes white & or black dots. May start out as one or two, then multiply.

See the following website for the proper DLP chip for your Mitsubishi model#:

Could be dead pixels depending on the TV.

Your problem is that the DMD device is failing. You're in luck, though. Mitubishi has recently released a replacement DMD device in order to keep repair costs down for the consumer. Take your TV to an authorized Mitsubishi servicer for repairs.

The dots can be caused by your power supply or by one of the sustain boards on your TV. You can get parts from www.interliquidparts.com

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".

The link to the article explains the the cause of the white syndrome none of the previous internet experts have a correct solution. I have the same problem the link to the article attached is for a Mitsubishi projector but all the chips are the same. http://www.fixyourdlp.com/2012/04/26/solve-the-mitsubishi-white-dot-problem-for-under-200/

the white dots (sometimes you get black ones too) are caused by a faulty DLP chip. you can find the replacement for your TV at the following website:
