Greetings, I recently purchased a Beomaster 5000 from a second hand store and had it serviced/cleaned. All of the buttons work great on the front panel but the left channel is extremely quiet and the right channel is working normally. The repair shop guy said he tested the output transistors and they are good. He thinks it's simply a case of the balance being set by the MCP on one side only and the solution might be to just change the balance back to center.I don't have access to a MCP (i'm currently looking on ebay) and the B&O dealer in my city didn't have one around either. Is there a secret sub menu or button combination that can allow balance control from the front panel? Any help/tips would be appreciated. Thanks.
Pressing NEUTRAL should reset bass, treble and balance to middle settings. If that doesn't work, there's some real problem.
(did you already try the speakers in the second pair of outputs to rule out a failing muting relay?)

Thank you for the quick response.Yes I've tried both speaker outputs. If I plug both speakers into the Right Channels I get a nice loud mono mixIf I plug both into the Left Channels I get a very quiet, tinny sound as if all the bass and most of the mids are missing. I'm wondering now if the Neutral button is not functioning correctly. I guess the only hope is to try the MCP and see if that can fix the problems with the panel. Hopefully it's not a more serious problem.
Well, it is possible that the NEUTRAL button itself is not working (unfortunately I don't have a BM5000 anymore to try, and I don't remember if pressing it would show any direct feedback). Faults in the front panel connections are rather common in these Beomasters, there's a ribbon cable that flexes every time the front panel is opened or closed.
