Why shutting down?

I have a Yamaha A/V HTR-5890, runs from a few seconds to 2-3 minutes, then clicks off. I have had it for a couple of years, no changes. I run a 10" Klipsch sub, Chorus Klipsch speakers, along with some older duel 12" MTX's, and a older smaller Advent's for surround speakers. It has never run hot, this is my shop system, so it's colder out there then inside.

Sounds like a thermal break somewhere. I would take it in or if you are so inclined start checking circuits for resistance. Also look for swollen capacitors. One last thought is maybe the power supply is done.

Check speaker voice coils.

I might try unhooking everything and see if it still does it and also running it in a typical temperature environment (how cold is it in your shop?). Likely something internally that the protection circuit doesn't like so you would need a tech to look at it.

May be your amp stands in damp/wet air?

I have a newer Yamaha in the shop now because it was shutting down. Waiting for an answer from the tech. I am guessing thermal protect circuit.
