Problem with blue dots on screen plus blue haze in lower left hand corner. Replaced lamp approximate 1month ago with Phillips lamp Assy. Blue dots started to appear about 1 week ago and are increasing in...


The optical block is most likely causing the problem. It will continue to get worse. Sony may help with the repair since they have had a lot of problems over the years with their optical blocks across many models. On the older sets they usually only help with the parts cost. The average repair cost for a optical block replacement is $1200.00 to $1500.00. So if they help with the parts cost it really brings the cost down. Their customer service number is 1800-222-SONY.
I hope this helps,

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.
