Panasonic SA-HE100 service manual

Or at least just the schematic. Fan won't come on and unit is overheating sometimes. All I can find online is repeats of a chinese site that doesn't actually have a download link, or at least I don't see it.

elektrotanya has is but it is a rar file. You will need an extractor, I use "free rar extract frog"

On the bottom left of Elektro Tanya page, below the preview window, it will say this:
"This file is downloadable free of charge. ...processing"
Wait until it says this:
"This file is downloadable free of charge. ...Get Manual"
Click on "Get Manual" & save the file.

Here is the Fan Circuit.

The fan circuit appears to be triggered by the Front Speaker output voltage.
Lotsa specified voltages.(with the fan Off.)

Thanks JazzBass! Not looking forward to pulling that mess all apart to try to find a sensing circuit fault. I'm leaning towards tapping the 14v supply and letting it run all the time, and calling it good. It's an old stereo, and nothing special.

Take note that the fan runs on -16 volts.
The + end of the capacitor goes to zero volts.
(remove Q773 & jumper E to C).
