What is the difference between a light engine and an optical block? My Sony has rainbow color splotches all over the screen. KDF-60F655. I heard that there was a recall for this problem, but Sony says that the TV is too old for them to honor it.
Light engine and the optical block are I beleive the same thing. This is an expensive repair.
I also own a 60" Sony rear projection (2 years old and so far so good).
Best of luck to you.

Light Engine and Optics Block is same thing, main part of DLP TV and multimedia projector to produce and project image on front screen.
Few manufacturer call it light engine and some says it optics block.
