STR-AV920

[sabre]

<font color='#000000'>I have the SONY receiver STR-AV920 and have a horrible humming/buzzing sound when we turn the sytem on. &nbsp;We do not have the receiver connected to the TV. &nbsp;Any advice to what we can do to correct this problem would be greatly appreciated. &nbsp;We already had this problem repaired about 5 years ago, and it just started again for no reason. &nbsp;We hate to pay 200 bucks to get it fixed since it is a 11 year old receiver. Can we fix this without taking it in for service? &nbsp;Any suggestions would be great! &nbsp;Thanks!</font>
