I got what looks like dead blue pixels area on my 4yo Sony KDF55XS955 Wega 55" DLVP HDTV, they just appeared all at once in a U-shaped pattern today in a lower center area of the screen. They are not visible on dark backgrounds (so they are not completely dead?)
I do not see any scratches or traces of impact on the screen (from kids). Any idea what about a cause and what repair may take/cost? Thanks!

Hi IV
The problem is one of your LCD color chips, basically the light passes through three LCD chips (red, green, blue) but in time they’ll get damaged by the heat of the light. These chips are inside the device called light engine, here you’ll see how the light goes through the light engine:

On this link you’ll see pictures of the same problem, pictures of the light engine and pictures of the color chips to get a better idea:

A new light engine will resolve the issue and they cost around $300.00 to $450.00 (I looked on Google)

Good Luck IV.
