Hi, I have just bought and received 2008 Beocenter 2. Finally it is working, after I learnt some new stuff about PIN and options for remote controller. I have an issue, though. Radio does not produce any sound, while CD plays normally. Antenna is connected and several broadcast stations have been found and saved. That would mean for me, tuner works properly. Still no sound. Previous owner was an older person, I have limited contact with. Before I pack and send back, is there any trick I should know about? (like options for remote, what took me some time to understand, being unknown concept) Thanks, Peter
