From the manual, you may have seen this: Switch off the unit, determine and correct the cause, then switch the unit on. Causes include: ?Shorting (bare wires touching) of positive and negative speaker wires. ?Using speakers with an impedance lower than that rated for this unit. ?Straining of the speakers through excessive volume or power. ?Using the unit in a hot environment without proper ventilation.

I think the house was hit by lightning recently and now about a second after the receiver is turned on it clicks and displays overload. I disconnected the speakers and everything else that was connected and it still displays overload shortly after it is turned on.
I have the panasonic sa-he70 av control receiver and it continouosly clicks off and says overload. It has been working fine for a while but just recently it is starting to malfunction. it works good when i hit the reset button and it plays the sub and two front speakers only. When I try to change to SFC mode and turn the volume past 40 it overloads instantly. I have checked all wires, disconnected speakers, checked for overheating and it has worked in the same circumstances for the past two months. whats going on?
