... very likely just a corrupted datebase, but possibly a hardware problem ...
Step 1
- disconnect the BM5 from mains
UNPLUGGING THE MAINS (FOR SOME MINUTES) IS THE ONLY WAY TO TRIGGER A TRUE "COLD" START!
- That's a good moment to safely check / "clean" all connections of the BM5 (disconnect and reconnect)
- restore power, let the system boot and check if everything is OK
if not ...
Step 2a - only if BM5-SW is 6.03.xxx or higher (if SW is an older version, proceed with Step 2b)
- let the unit start, enter the service menu, select "maintanance" and select "delete database"
NO MUSIC FILES WILL BE DELETED - JUST THE DB WILL BE DELETED AND REBUILD AGAIN
- rebuilding will take some time, so be patient ...
if the problem still exists ...
Step 2b
- reboot and select "recovery" at the boot screen
- if you do a system recover you'll lose your favorites/playlists and have to reconfig the system again
- after recovery trigger a manual SW-Update
if the problem still exists ...
Step 3
- very likely a hardware defekt - contact dealer / service
