Blue dots and blue screen on Hitatchi 50"

We have a Hitatchi 50" rear projection tv that started out with a blue circle on the left side which has now turned the entire left side a blue hue. There are also several pin head size blue dots throughout the screen. We replaced the lamp approx. 6 months ago. Other than this blue tint and tiny dots the tv is great. Can you help?

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.

Lots of small blue dots


The Optical Block is the most likely cause. It has been known for this problem. The cost of the Optical block in this model series is approx. 600.00 or so.
I am not sure if Sony will deal with a Consumer on a one on one basis for this part because of the cost of the part. You can check with Sony at 1800-222-SONY.
I hope this helps,

Two blue dots on the screen


its sounds like the guns has burnt your yube, when switching of does your tv show a bright circle in the middel, or while watching. Smack your tv on the side while on see if the picture goes away or make a bright circle in the middel, this is caused by a bad solder joint but you wont get rid of the bunt pixels sorry.
