Question about Sony DAV-C770 System
As the volume is turned up, a strong hum comes through the overhead speakers. If I disconnect the top white and red connections in back of the unit, it goes away, but so does the volume in the above speakers. What is wrong?
Are you running a stand alone dvd player or is it built in?check all plugs for sources coming ineg.dvd,vcr,xbox etc,if one is not in all the way,this will cause a hum.
