Question about Panasonic SA-HE100 Receiver
When I power up it displays switch off overload, even with everything disconnected.
I was able to fix this problem by replacing a fuse. Remove the cover (7 screws). Directly behind the fan are 2 boards with 5 fuses on them. The boards are 1 over the other. The fuse I replaced was labeled F5 and on the top board with the fuse facing down on the underside of the board. This also fixes the error code F70. The fuse is 8 amp, 125 volt and not available at Radio Shack.

I had the same problem, in that the receiver would automatically shut down displaying the "overload" message. I checked the 5 fuses inside, as well as ensured that the fan was working. I was using six 4ohm speakers + subwoofer. All the speakers other than the rear center channel and subwoofer were ceiling mounted in the room.
However, I decided to check the overall impediences of each speaker line to ensure that there wasn't an issue with the speakers. It turns out that the net imediances of the four corner speakers and the front center speaker were 5.7ohms because of resistance in the long lengths of speaker wire I had. However, the impediance of the rear center speaker was only 4.7ohm -- because the speaker line was much shorter.
Thus, the quick solution: ensure that all the speaker line lenghts are the same, (to ensure that the overall imediances of all the speakers are the same). Once I did that, the receiver started working beautifully -- full loudness surround sound working fantastic.

First: Never power up any amp with no load. Second, if possible, test the speakers themselves with a multimeter. You should get a reading of a few ohms on each...but not a direct short nor an open. Unplug the unit from the wall and repower it. It may reset something. If this doesn't resolve the issue, you've got a repair bill.
