These white dots are a very conmenissue when the DMD board is
starting to go bad (the integrated DMV chip). The DMDcontrols the color
wheel and the light engine; it’s in charge of manipulatingthe light
engine so it can project a picture on the screen. A test you can
try:bring up the TV menu. If the white dots appear in the menu, then
that willi ncrease the probability of a malfunctioning DMD, if not then
the digital video board will raise suspicion. Now if you decide to buy a
new DMD you’ll have to search by part number, NOT by model number, the
main reason is that two TVs the same model number may have non
compatible components because they are different generation when they
where assembled.
Also if by any chance you can’tfind the
DMD sold separately, your next option is to buy the entire lightengine
that includes the DMD, and obviously that’s going to be more expensive.
If you're trying to save lots of money and you really know what your buying
try eBay,you can get a really good deal, how ever if you are not
familiar with TV parts,and don’t want to take a chance buying something
that might not work, try online stores that specialize in TV parts (my
personal recommendation: Discount-Merchant
