I have a Bose lifestyle 28/35 with a PS48 subwoofer. It has worked great for a while but all of a sudden it sounds like a helicopter or a machine gun. Something like "tha tha tha tha tha tha" I have disconnected the media untit (AV28) form the subwoofer, one speaker at a time, and all sorts of combination. Does anybody know what the problem could be.
the soobwoofer PS48 has a cable that connects it to the media center AV28. It does not make any diference if that cable is disconnected or not, the sound remains. Wires for all 5 speakers come from the PS48. There is no way to disconnect or bypass the subwoofer. I wish I could to be able to test the system without the subwoofer
That does create a troubleshooting problem but I think this noise has been narrowed down to the PS 48 or the wires. How far is the run between the media unit and the subwoofer? The best chance of fixing this problem is that perhaps the wires are picking up a noise. Can you reroute the wires?
I would doubt the problem is the wires because if all speaker wires are disconnected from the PS48 the noise keeps coming from it. Obviously no sound from any of the 5 speakers because they are disconnected.
hey jae how about dumping the bose and starting over again,
sell it on ebay.. I'm sure jim and I can recommend something way better.. sorry to ruffle some toes but your better off jim knows, and sound quality would vastly improve ..if you do let us know a budget.... if not try a local repair guy to test whole system.
The LR channel does not always have sound unless dictated by the unit. If you have a test cd that will send tones only to the LR channel then you can narrow it down if it is a unit probelm or a signal issue.
