SOURCE: white dots on tv screen

The white dots that come and go could be what is called ignition noise. Caused by something in your residence or on the power line to your living area. You will have to do some tracking. Take a portable radio and tune it to the 550mhz, you will hear a crackle or buzz, tune to the loudest that the buzz/crackle can be heard. Walk around to see were the noise gets to be the loudest. If it gets weaker you are moving away from the source. The source could be a dimmer switch for lighting, or a loose connection on a receptcle, or in the panel box that supplies the residence. Worst case it could be entering from outside source. I have tracked ignition noise as far as two houses away that had a bad butter control on a refrigerator that was on the same power line that supplied the neighbor hood. There are so many things this day and age that could be causing your dots. Yours come and go, so you will have to track it when it is acually seen on your tv. Sounds like something on a timer like refrigerator, Furnace, etc.

SOURCE: White dots appearing on Samsung TV screen and multipling each day

It seems you might have an issue with the dmd board. Go to the menu, and if the dots still show on the menu, the issue definitely is with the dmd board but if they don't come up on the menu, the issue will be with the video board.

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..

I believe it is the digital projection chip that is beginning to fail. Causing white and black spots to appear. To repair this may cost more than a new tv. If you want to attempt it yourself check out the above link. Hope this helps

My tv has small white dots of lights in most of the screen can this be fixed.


Ensure your input device is not causing this, by changing the TV input to a different video device. Then, look for any loose contacts on the RC cable or input cable. If nothing works, better refer it to a qualified service technician.

I have black and white spots on my 52" samsung projection tv screen


White dots usually indicates that the DLP chip is failing and will need to be replaced. This is a repair best left to a technician. You can call 1-800-samsung to see if this repair would be covered under their white dot warranty, some models are covered.

White spots on TV Screen


<span id="ctl00_ctl00_MainColumn_CenterColumn_ThreadSolutions1_Repeater1_ctl00_lblSolution">DLP/mirror chip is going bad. A common problem on Sammy TVs after 2-3 years. Chip is user replaceable (try samsungparts.com or ebay) for about $150-200. Sammy was (last year) repairing the DLP White Spot problem for free. You MUST talk to ECR (executive customer service) to even think about getting that consideration--forget the standard CS people. Don't know if they are still covering this out of warranty in 2010.</span>

Yellow Spot dead center on screen


most likely the yellow dot is due to a burn in the picture on the "green" lens. It's not removable because it's burned it, but you can try cleaning it because sometimes, dots are caused by dirt. The worst that can occur is that if the dot is permanant.
