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.

Yes,it is repairable.Blue dots on screen is sign of LCD failure at optical block assembly. There are three LCD on the optical assembly RED,GREEN and BLUE. Blue LCD failure causes blue dots on screen. Repair should be done by replacing blue LCD. Note! LCD replacement needs Extra care and precise tools such as oscilloscope and color pattern generator , for the color alignment after replacing LCD.

Blue dots on my lcdtv


Sometimes the voltage can be set to high by the factory. Throughout time, blue dots will appear. You will have to remove the back cover off the tv, find the "voltage Screws (they are labeled) and turn down (left) JUST A Notch. Have seen this done many times.

Pray that the panel isn't blown out or bad projector tubes. They are expensive.

Blue dots and screen flicker are VERY common on the newer LCD and Plasmas

Also, if you have a pixel setting on your TV (not sure if that one has it) Try setting it to
480p.
