Beolab 7-1/2/6 failure states

2 replies

Hi!

Do someone know about the way the failure system indicated by the LED is working?

Speakers connected?
IC boards connected?
Ground/Chassis connected?

All together? Or a more complex way to raise system failure state?

 

Thank you!

A little backgournd:
I need to run the speakers outside its original cabinet. The woofers were still inside and thus couldn't be connected to its PCBs. The LED went yellow when turned on, so i conlude the woofers are missing by the PCB.

Now i finally got the woofers out and could reconnect with its wires. Plugged in mains and PL, LED went to green, but no sound. So i still miss or ruined something.
The wiring looks good compared with diagram in service guide. The to bad there is no current on PCB 2-P4 or PCB 4-P10.

How to check PSU? :P
