Cyber CL logic board LED's

Good evening,

I wonder if anyone can tell me what the 3 LED's on the front of the logic board for the cybers stand for?

There are LED's,

yellow - red - yellow
LD9 - LD5 - LD6

Also, how can these help me troubleshoot, as some of the boards I have have all on, and some only have the yellow ones on.

Thank you in advance,

Alexis

sounds like the voltage indicator LEDs no?? check the LEDs on your power supply board (on the other side of the lamp box from the logic board)...if you don't have all three LEDs there, you either have a blown fuse on your PSB or your transformer is partially dead and needs replacing. If you do have all the LEDs on the PSB, then it is probably the 14-pin harness (that connects the Logic and PSB) gone bad.
