Some Sony receivers depend on the screws that mount the pc boards to the
chassis to ground parts of the circuit boards. Works great till the
screws work themselves loose, then you have intermittently ungrounded
circuits, causes the units to go into protect intermittently. Also the
screws between the RCA jacks on the back of the unit provide a ground
path for some circuits. All screws must be re tightened and some should
have a hardwire ground added.
