KDF-42A12U Blue spots on screen, getting worse

[time2innov8]

I have an issue with a 42 inch DLP television that has blue spots on the screen. The visibility of the blue spots is increasing on a weekly basis. An internet search has identified that the optical block may be the cause.

Has anyone experienced a similar problem and what was the solution?

Hi if you are experiencing issues with picture quality it could be an issue with the optical block or the lamp, if you remove the lamp and check it is clean and then try again it may resolve issue, however if it remains the same only an engineer could advise further, as the unit would have to be dismantled
