What is the difference between a light engine and optical block?
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.

Hi, If tv is Sony KDS-R60XBR1 as shown in question headings then it is problem of optic block (light engine) that needs to be replaced, it is hardware problem that wont get solved by resetting. Optic block is expensive part and qualified tv tech is required to replace it. If tv model number is different, please post it to provide you info about problem. Thanks.
It is the optical block causing the problem. Sony has had recalls on a lot of the LCD rear projection tv's made over the last 6 to 7 years. The cost of the optical block is around 800.00. Due to the cost, I would check with Sony to see if it qualifies as a recall situation.
I hope this helps,
