Thats a very common problem caused by the optical block needing replacement. However they are very expensive and usually not worth repairing.

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.

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.

You need to replace the dmd board.In some cases it is more cost effective to replace the entire optical engine which includes the dmd board,lamp,ballast and color wheel for about the same amount of money and is easier to install.

White dots


There might be an issue either with your DMD board or your Video board, with the tv on, go to the menu, and if those white dots are still there the issue would be with your DMD board but if those dots magically don't show up on the menu, the issue would be with your Video board
