The dots are most likley the optical Block ( light Engine ). The not powering up issue could be numerous items , have you tried accessing the self diganosis feature with the power indicator blinking an error code?

If the white pixel dots start to multiply then Problem will be in the DMD board or the Light Engine.

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".

It sounds like it probably is the DMD chip, so I'd go ahead and get that looked at!

This problems is the tv Projection Light Engine design flaw with it IC chip.These problems happen to many models of it DLP tvs Big Screen 60 and up.Mitsubishi,Samsung,Sony,Toshiba all used the same IC chip on their 60 and up on their DLP tvs Big Screen.Tries make deal with Mitsubishi help u split the cost of repair the tv Projection Light Engine by replacing the IC chip or replaced the entire Projection Light Engine system.This problems is not new,been going on for a few years.Many people when on Youtube **** about this problems with white dots showing up on their tvs screens and multiplying rapidly.

Call Samsung! They do recall even if it's out of warranty.
They set a tech to come and fix it for free.

sounds like heat got to the optical block, there are some websites that can give you prices on rebuilt opt units, but i suggest that you take a look at the sony website and check the factory recall section to see if there are any re-calls on your particular model. These optical units are kind of expensive.
