maybe someone can help me,
we bought for our school a used Light-system with a Sirius 24 Desk. ( we have only a very low budget…)
My problem is now, the desk seems to be ok, but it has no output ( 0-10V)
The programming part has function and the preview LEDs are running, but also in
“preset only” there is no output.
The powersupply is running and all the 5V and 15V regulators are ok.
At the output transistor I have aprox 18v but they do not open. (green output LEDs are also dark)
is there any help with a circuit diagram or a service information to repair the desk ?
We are a little in hurry to have it ready for the next weekend for the school-party.
