What is a DMD Chip?
Its a DLP chip Basically its alot of super tiny mirrors that open and close at various times to produce the image. The dots your seeing are mirrors that have stuck and the only repair is to replace the DLP chip which is easy but pricey 300.00 you can get repair kits with installation instructions from www.tvrepairworld.com

Its the DLP IC chip itself that is bad. The DMD board is where the chip resides but if you order a board, it will come without the chip. Its not cheap and the replacement is tricky because the DMD board must be removed and then an alignment of picture centering will be necessary.

Make sure you have firmly seated the new Lamp. The next step is to go to the rear of the set and put your ear next to the Lamp Door while turning "ON" the tv with your tv remote.
You should hear a short buzzing sound. That is the Ballast "Exciter" firing up to light the Lamp. If you do not hear this buzzing then you probably have a bad Ballast. Ballast part# is BP47-00037A

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.

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..
