I work with a church that just purchased 2 technobeams from a Blockbuster that was closing. They claimed that they worked great for about a year until the lamps went out and they never replaced them. Upon firing them up, I have found an issue with each of the fixtures.
On fixture 1, the mirror will not pan or tilt. The motor LED on the control panel is red, which according to the manual is normal. I tried going through the test menu to the Pan and Tilt tests and the mirror still does not move. With the power off, the mirror can be moved with little resistance. With power on, there are definite "steps" as I pan and tilt the mirror. I read on the forum that this is likely a result of a bad 3773 chip. I will try moving the chips around to see if I get the problem to move ,but I wanted to see if I am on the right track with this one.
On the second fixture, things seem to be working, but the display shows sensor 2 error. Upon inspecting the fixture, I noticed that some of the teeth on the FX Drive gear are damaged. I was wondering if that was causing the sensor 2 error.
I look forward to any input.
