My fiber optic lights will not light up. I purchased a new bulb and it still doesn’t light up. If I replace the bulb socket, is there any other possible reason why the light will not come on. The fan, and the color wheel are working.

Mitchell, Does your system have a fuse? If so, I would check that as well. If replacing the socket doesn't work, it may be time to replace the illuminator.
