Hello, I have 4 AccuScan 250 lighting units. Recently, the lights on 2 of the 4 stopped coming on. The motorized part seems to still be working, just not the bulb. The users manual troubleshooting guide suggests checking the bulb and the fuse, which I am in the process of doing. The fuse seems to be fine, I have to purchase a new bulb to know whether or not the one in the unit isn't working unless it's supposed to be obvious when one is burnt out. I have one on the way to me and should be here tomorrow.
If it turns out that the bulb is fine too, what other reasons could there be for this to happen? Could it be in the programming? If so, why are only 2 not working? I don't know much about these lights yet, they were installed by a light guy who isn't available to help me anymore. I guess I'm just looking for some advice on what else I can check before I am forced to call for service. These lights are not very old. Maybe a little over a year old, and installed in a nightclub. Any suggestions would be much appreciated.
