No, I am not willing to repair myself, but thought I'll ask here anyway.

SA-HE100 Panasonic AV Control Receiver. Bought in 2004.
Suddenly it broke few weeks ago.
After some time being on, display keeps saying OVERLOAD.
At first I thought it might be when muting. Nope.
Then the B speakers with some sort of a mixer my DH built. So pushed the button to not use the B speaker (It's a one big tube). No go.
Now, starting today, it says Overload as soon as I turn it on.
Old age, me and it Sad

Manual says possible causes: shorting (bare wire touching of + and - speaker wires, Low speaker impedance, playing too loud, hot without ventilation.)
None of these apply. I haven't touched any wires all these years. Except removed cassette player (it broke too over a year ago) so the 4 RCA wires are still plugged in but I have them taped to the shelf and they touch nothing.

Is it a goner? I can't even lift its 23 lbs.

First step, physically disconnect all of the speaker wires from the unit. Label them first if you want to. Still overload - internal failure, probably output stage shorted. Given advancements in tech, I'd replace the amp.

No overload, either a wire has a short (even the smallest tag end of wire can cause it) or a speaker has shorted. A bad element in the speaker might be replaceable. Wires can be replaced.

Is it yourself that needs repairing, or the amp? Wink

LOL. Both Smile
I wrote it like that because the description of the Electronics forum says "... and you're willing to do the repair yourself,..." which I wasn't willing to do.

I'm slowly following Steve's advice. The receiver hasn't overflowed with all but optical cables pulled.
Speaker wires have no little wires hanging off because we soldered both ends. I'm plugging in a speaker at a time.

Yeah, the idea behind this forum was to make the most of Steve's knowledge, along with anyone else who has relevant knowledge, where we help people by telling them what they could try fixing.

From reading what he wrote, if you're not getting an overflow with all the cables removed, I think that's a good sign, as it seems to imply that your amp is ok and it's either your speakers or your wires that are the problem.

Well, it definitely looks like the amp is OK. There was one questionable speaker wire possibly munched on by a cat. Two days with different inputs and many on-off sequences - no problems.
So, many thanks, Steve Smile

Rob and Steve:
One quirk that makes me think it still might be something inside the amp. Now, don't laugh. I wanted to push it a bit into the shelf and one rear foot slipped which I didn't notice. Subsequent power on resulted in OVERFLOW. Hmmm.

Oh yeah, it's well known that if the rear foot slips off you'll get an overflow, lol.
