My mom has an Onkyo receiver and a Polk surround system (4 surrounds, center channel and powered sub). She also has a 36" Vega and DirecTV (with cable for local channels). Their house was recently completed, and the surrounds have their own outlets for the signal wires. The powered sub does as well.
There is a pretty bothersome hum (or buzz) sound emanating from the sub, whether the receiver is on or not. The "Auto On/Off" feature does not seem to be working, either.
I've tried a number of fixes, but to no avail. Mom even had the electrician come and re-wire a new RCA wire to the plug in the wall b/c I felt that maybe there was a break in the existing line. This didn't fix the problem. It has gotten to the point where she wants to just give it to me. Which, of course is fine by me, but I feel guilty. I had brough it home with me to try it out on my system to see if it hums here (it didn't-BTW).
I was thinking that maybe it is the receiver, but that shouldn't be the case b/c it's a pretty good Onkyo. (for all I know......) I KNOW that someone's had this problem before; and has found a fix for it. Can anyone advise what to do to remedy this?
Thanks in advance.............
Nice forum here BTW.
