I the same problem and I found that the Capacitors used on the power supply portion of the circuit board were leaking and/or bulging. These parts were failing and as a result the problem worsened with time. If you are able to remove and solder new parts on to the circuit board follow the following procedures. Or get a technician to do the repairs.
1) Make note of connections at back of TV.
2) Unplug power cord and other connectors from back of TV.
3) Remove back of TV with a Phillips (+) star shaped screw driver.
4) Note the position of all connections to the main board.
5) Remove circuit board taking care not to damage any of the components.
6) Locate parts CM806, 811, 812 & 817, all 1000 uf 10v capacitors.
7) Remove and replace parts with capacitors of equal physical size that are (1000 uf ). I would recommend a voltage rating of 25v or 32v. Note that the voltage refers to the amount of voltage the capacitor can handle. The higher the better.
8) Reinstall and reconnect the circuit board.
9) Replace back on TV and setup the unit as before and you’re done.
I replaced the parts for just under $10.00.

Random dots or pixels failing on a DLP TV will be a bad DMD chip. This is a technician replace item only. The chip runs around 160 dollars list price. The part number will depend on which version the set uses and will be determined by the technician.

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..
