  • Re: Beomaster 5000 very soft sound?

    Your tenacity is admirable,but this is getting to be a real puzzle! Alex has a point about shorted speaker wires,but this would not affect both channels surely? I assume that voltages around the power output stage are correct? I'm still suspicious of the pre-amp/volume control stage,particularly as you have no volume control pulses? I'll break

  • Re: 7802 No sound . .. Help!

    Another favourite with this set is after you've been using your i.pod etc headphones via 6.5mm adaptor,you remove the headphones,but leave the adaptor still in the socket.This cuts out the speakers of course! If not the above,do you get sound via peripheral devices eg,vcr,sat etc?connected to the av sockets? You may have a problem with the supply

  • Re: Masterlink cable length problem

    I had this problem also after making my own junctions! I was advised by an installer that you have to use the correct B&O boxes,as there are internal links which if not present,can affect the configuration.They are horrid fiddly little boxes,but it did overcome the problem. I imagine if you new which wires had to be linked,you could hardwire it

  • Re: Beomaster 5000 very soft sound?

    It does seem as though the interface chip ic5 is at fault,as both channels are affected.It provides the volume control pulses which are converted inside the volume control chip ic3 to a varying dc voltage.If you use a logic probe(available cheaply from hobby shops)you should be able to see a pulse at pin 9 of ic3 when you alter the volume.If it's

  • Re: Beomaster 5000 very soft sound?

    This could be due to the "muting" system being stuck "on".It's designed to mute the sound between functions,and when tuning between stations.It's controlled by the computer and interface chips.

  • Re: MCP 5500 flashing

    Use Duracel Chris,all those bunnies can't be wrong?You might also check the connectors for corrosion etc.The MCP (inevitably?)has a rather sophisticated standby supply circuit,that can confuse the issue,and suggest low batteries.I've had some panels over the years that seem to "eat" batteries,due to various internal maladies. Try some

  • Re: Beovision MX 7000 imediately turns of

    The set does indeed have self protection,as do all the B&O telly's of recent type. The "powerfail" system checks for real faults and "bus errors",and shuts the set down if it's not happy. You really the full manual,as this gives an overview of the design,and service tips. There were several variants to the chassis,but

  • Re: BeoSystem 4500 and the Glass Panels

    You can buy a repair kit from B&O,that provides enough of the correct tape to do several repairs.It's special thin tape and very strong,but you need patience to get it right.You need to clean all the original tape and glue residue from the glass and the plastic holder,to ensure that the glass sits evenly.A glue remover will work,but don't

  • Re: Beocenter 9000 Tuner Issues

    The tuning is carried out by the computer,which scans through the band locking onto stations depending on signal strength and frequency feedback from th tuner module.From your discription,it seems that no feedback is reaching the computer,although it's obviously tuning! I suspect a small processing chip has failed,I've come across this before

  • Re: Beosat help required.

    Indeed,a useful piece of kit.I think it's made by an outfit called Blue Delta Design.You can probably get more info direct from them,although maplins own techie folk are pretty helpful too. As to your satellite tv problem,I think the ODU90 motor is a "tacho" feedback type,and may not function with your Echostar? I remember that the B&O
