The dots vary with scene content and vary over time. They do seem to get better (but never go away completely) when the set is left on for a while.
There is a degree of adjustment on the Y-sustain board, and sometimes they can be tweaked to produce a better picture; With these two adjusting gave you a choice or bright dots or dark dots - no happy medium.
I have read that the dots can be caused by bad caps on the sustain boards, but I have tried recapping them in the past and it did not improve the picture.

The pictures of those "dot" issues don't look that bad to me, I was expecting dots the size of dead pixels in an LCD TV but those "dots" are barely noticeable, I had to look really hard at those pictures to even see the "dots" you were talking about. I haven't checked eBay recently to see if there are anymore Y-Sustain boards for sale that are under $80 or not (as I would like to try and keep the repair costs on this TV down as much as possible so I can try and make at least a little money off of this TV when I go to resell it.
