Thanks for using JustAnswer
Is it like this on other inputs like a dvd?
If you press the menu button of the sets own remote control can youstill see this over the menu screen?
I'm sorry. I replied yesterday but I guess you didn't receive it.
The blue dots are visible on other inputs as well as when I try to play a DVD. They are also visible over the menu screen.
This is a bad light engine i'm afraid namely the optical block please read this article about this issue then ring sony as they have been offering discounted sets and depending on which model free as well
Its no use really having another light engine fitted as theirs no gaurantee the issue wont crop up again at over $1000
Let me know if you need more info please
