it seems like you might have an issue with your dmd board. Go to the tv menu and if the dots also show there, the issue is with the dmd board, but if they don't, it's with the video board

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.

Are they spots or dots? If they are spots then the optics are contaminates. If they are dots either white or black then you have a bad DMD chip. The cost of repair depends on who you hire to repair the set or if you do it yourself it depands who you purcahse the part from.

Well for what you describe it sounds like the symptoms of a worn out lamp giving you the last kicks,basically the the lamps are design to go for 6,000 to 8,000 lamp hours if they're Phillips and a generic lamp could give you 3500 to 4500 lamp hours so with this in mind you could search for a new lamp at Discount-merchant.com or you can go to Ebay also you can go to www.fixyourdlp.com for more troubelshooting
