I have the same model and it did the same thing. Have you received any ideas?

i have an SA-HT80 when i turn up the volume at -28, suddenly display f61 an shutdown, the owners manual said there is an short between the speaker wires, also i replace the power module IC501, but the unit continues with the same failure, i pay $60.00 for the power module here in PUERTO RICO, SOMEBODY HELP ME !

Had the same error code, whomever hooked up speakers shorted them out causing the F61 error code when turned on. I have read some other solutions and decided it was IC501. Replaced it and unit works like new. Be careful to stip only about a half inch and watch polarity when hooking up speakers. Steve
