Since I posted before, I actually had another black dot appear. By this time, I'd already got the ball rolling with Samsung (November 24th) and then on December 17th, Samsung sent out a repair tech who swapped out the chip for a newer one.
As I thought, this fixed the problem and I now have no dots at all on the screen.
One thing that surprised me was that the chip that had gone bad was date stamped 2002. The TV was purchased new in Fall of 2006 so it struck me that this was an old chip to begin with! The replacement chip was dated 11/09/07.
I wonder what the story is there?
I originally reported this issue to Samsung on October 13th, 2008. They gave me the obvious brushoff as it being an out of warranty fix, requiring a full light engine replacement and the costs being $358 for parts, $220 labor, $85 service charge - grand total of $663!
In the end, Samsung took care of it at no charge and only replaced the DMD chip.

I can't help feeling that replacing the DMD chip would fix it but it looks like it is a) not a model that has been mentioned yet and b) also not easy to even get the chip for it.
When I enter the TV details on Samsungparts.com or the other parts websites, it doesn't offer the DMD chip alone - only the light engine at $800 or so!
The TV is a Samsung HL-S6187WX/XAA, with PF01 DMD card.
It is in the same line as the HL-S5087W and HL-S5687W.
Does it use the same chip as any that have been mentioned so far in this thread?
Admittedly, I don't have nearly as bad problems as many have experienced and for some reason, my "spot" has stayed at just one for over a year now but with it being central on the screen, it definitely spoils the enjoyment and is hardly considered normal.
I've filed a complaint with New Jersey Consumer Affairs Department and it sounds like going that route gets results with Samsung, so waiting to see. If that doesn't work for some reason though, it would be good to know I can get hold of a chip and do the repair myself.
Thanks for any advice.
