I HAVE WHITE AND BLACK SPOTS ON MY SCREEN THAT COME IN AND OUT BUT NOW I HAVE WHITE SPOTS THAT ARE THERE ALL THE TIME WHAT SHOULD I DO

White spots or dots showing up on your TV's screen could be the result of a bad or damaged processor or due to some overheating occurring the summer time or cold weather temperatures during the winter time. TVs can be affected by electricity surges or spikes as electricity supplies vary throughout the year. Or power outages and brown outs and black out can also cause spots to be on the TV screen too.

Bad controller board probably, other makes have this problem too.
If under warranty good, if not bad.

The DLP Chip is failing .The DLP or Digital Light Projection Chip contains up to 8 million tiny microscopic mirrors that tilt to project a digital image onto the screen. These mirrors are failing causing light and dark spots to appear.Unfortunately fixing this projector is probably going to cost more than buying a new one. Hope this helps.

Is this a touch screen?

You can use the following website to try and fix some of these pixels that are stuck on the wrong colors:

However, it may just be a defective screen. You may need to have it replaced under warranty (and this most definitely will be covered)

optical engine failure. that technology is called DLP digital light processing and it uses a device called a DMD digital micomirror device that has millions of mirrors onthe face and they independtly move and sometimes they can get stuck or not move and cause spots black or white across the entire picture. i suggest calling customer support for possible repair accomodation

It is the chip that controls the millions of mirrors inside the tv. If they are black, they are stuck closed. If they are white, they are stuck open. I JUST had the same the same thing happen with mine. I bought it 3yr and 2 months ago and I had an extended warranty on it for 3 years. Well, needless to say, it was out of warranty and I was pissed. The store I bought it from suggested I call Samsung. Which, I did. They asked for the model number and told me that my model (hlt5675sx) was one of the ones that is covered becasue they had a problem with the chip. Within 2 weeks, my tv was fixed by a repairman who came to my house. It works perfectly, now and it didn't cost me a penny. Good luck.

your dlp ic is going bad and needs nto be replaced. some of the mirrors are getting stuck they will appear as black dots or white dots. it usually starts as one or two and will continue to get worse over time.

Well here's the scoop. White spots mean that the mirrors are stuck "on" reflecting light. Black spots mean that other mirrors are not actuating and are not reflecting light. In any case the DMD bs or the DMD chip needs to be replaced by a trained Samsung tech only.
The DMD bd controls the DMD chip.
