I put my Pioneer receiver in my enclosed gazebo outside, with the hot tub. Unfortunately, it won't power on, so I thought it might be because it is sooo cold (10 degrees), but now I am thinking the humidity and the cold have done something. Any ideas, could this be a fuse or an easy fix, or did I destroy it by having it outside?

First of all shut it off. The reason it is losing sound because it is cooking itself to *****. Depends when you purchased it as to whether or not it is under warranty.

check the fuse or ic regulator

My first guess would be the fuel pump relay or the ignition module.
Look for something that gets hot and fails like a relay or electrical part.
When it won't start, check for spark at the plugs and the fuel pressure.

this is taken right from a jewel series QCA hot tub manual.....Winterizing
In very cold weather you may not want to venture outside to use your spa. In this case, you may move it to a heated area, or leave it as is until the weather warms. If you do leave the spa unused for a long period of time in severely cold weather, you should winterize the spa to avoid accidental freezing due to a power or equipment failure.. Follow these easy steps: Turn power to the spa OFF. Drain the spa. Use a wet vac to **** or blow out the air injectors, water jets and water suction fittings. Add 1-3 gallons of RV antifreeze, depending on the size of the spa, to all the air injectors, water jets, suction drains, and filter. Caution: Any lines not receiving adequate antifreeze are subject to freeze damage!

the power wiring is not correct. Pls test the wire you put on the red cables for power with a gauge

add kudo's if solved

service manual above...

If your reciever is in a tight enclosed space, than it will overheat and shut down to protect itself. Try to get some ventilation to it by either opening the cabinet door, adding a fan, or pulling it completely out of the enclosed space.

sounds like it is over powered .. are your speakers rated at the same wats the receiver is putting out.

With the receiver off, press ENTER + ADVANCED SURROUND keys continuously for 2 sec. and it will tell you the fault it encountered. Even if it has a short, it will still protect the speakers; however, it is still a good idea to disconnect all speakers before doing this.

Thats why you buy insurance.
