Hi,
I am just about to break into LF and am already having problems. I just purchased a used Dichro 45 Computerized Colorhead and need to troubleshoot a problem. The bulb will not light up. When I purchased it, the guy stated that he had not used it for awhile and he thought that the bulb was burned out. Everything else worked great. I bought new bulbs and none of those work. I tried plugging the timer cord into my newer model Gra Lab timer and straight into a 120 outlet. No deal. Everything else on the head works fine. The fan runs and the LED displays light up and give read outs when switching the white light lever. Can anyone help me with this?
