Re: Technobeam issues and questions...
Make sure the
voltage and frequency are set correctly on the switches. Also the
fuse should be a 6.3a
fuse. Make sure all of the proper fuses are installed including their blow speeds. Usually fuses protecting the lamp circuitry are slow blow due to the
current inrush and fuses just protecting the electronics are fast blow. If the
fuse blows as soon as you
plug it into the wall I bet the rectifier bridge that converts AC to dc has shorted. I have replaced quite a few in techno beams due to people not having the
voltage selector switches set properly. If the lamp
fuse is the proper size and type and is blowing when it lamps on then there it could be a bad
ballast, Ignitor, or shorted lamp wiring. The
gobo error could be due to a bad motor, try spinning the motor by
hand if it is easy to move than the motor is probably good.
Power up the
fixture and see if it try's to move the
gobo wheel if it does and the wheel keeps spinning than it is a problem with the optical sensor. I the wheel does not move than it is a problem with the
driver chip. Some technobeams have a spare chip installed in the slot labeled spare you can pull the one out of there. The
driver chip is a 3773 that is available and most large electronic stores.
