I had the same problem with a Sony VPL CS1. It's not the mainboard, but the blue filter - cost to repair runs around $500 US.
Hope that helps.

I also have the same problem -- the fix is to replace the optical block ( Internal lamp engine ) which is a $1,100 part. I just purchased a used projector for half the price of the part.

According to the manual, you need access to the RESET button, the left and right arrows and the ENTER button to clear the counter. Press the following in order for less than 5 seconds each:

RESET
Left Arror
Right Arrow
ENTER

The above sequence should clear the counter.
