You have a optical block issue. Contact Sony support to see if they are still honoring the extended warranty. This can be done from the web or by phone. It's likely you will need to speak to them if the extended warranty has expired. NOTE - this is not your warranty, but a Sony accomodation for a early production issue.

I have blue dots on the screen. I cleaned the glass on the projection bulb and the prizm but still have blue dots.


Your tv is an LCD projection one - in which the image is generated by 3 small LCD screens. The blue dots are pixels from the blue LCD that are dead - always fully open.The only fix is to replace the LCD panel and that is going to cost you around $300.
