Hello,
Thanks vor the schematics posted so far, im looking vor the first 27 pages of the manual.
i seem to be unable to PN the user who said he had it.
Is anybody here who has it?

Backround:
My BA-330 does not make a sound or light any LED anymore. So far i was able to find out that fuse F5 blow. Replacing it i can see a saw tooth voltage over (current through) F5. So somethink is detecting an error and reseting. That does not occure when I disconnect CN6 so the problem seems to be on the "CH PWB Board Assy" of which the Schematic was not yet posted.

Regards

Eike
