My receiver has been sitting in a garage for about 12 months now. During the summers here it gets to be around 100 F and in the winters it is around 75 F so you can imagine what it has been exposed to (I know - very stupid on my part to leave it in the garage).
I hooked it up today and it will turn on for about 2 seconds later it shurts right back off. No matter how many times I press the power button (I tried 20+ times once) it would never stay on. It just kept powering off immediately. I tried changing to a different outlet but got the same problem.
Any thoughts? Is tehre a fuse that might be tripping?

Re: Powers on but immediately shuts down
No I hate to be the one to give you the bad news but most likly the capacitors in the power supply or the output circuit of this reciver, are bad and most likly need to be overhouled. Or there is mosture contamination on the printed circuit board. It is time to let go and buy a new reciver, unless you want to invest big bucks into the repair of this reciver, as Im sure it can be repaired, but at what cost??

it is the cam position sensor...the telltale sign of the failure is that it happens when the vehicle is warm and has been driven for a while. Sensor is about 40 bucks at the auto parts store, make sure the replacement sensor is metal, not plastic. The main symptoms of this sensor failing are rough starts, rough idling and not starting at all especially when warm.
Maybe your laptop is overheating. Does it power back on immediately when you were using the power cord or do you have to wait and let it sit a while to cool off before it powers back on?
Do you hear the fans running when you power on the laptop?
Laptops overheat because of: 1) Dust around the vents, CPU and Heat Sink. Dust inside the laptop. 2) A Fan that is not working 3) The Thermal Paste around the CPU and Heat Sink has dried up or is too thin to keep the laptop cool.
If it's not happening when your speakers are disconnected, your problem is not in the receiver, it's either a wire touching at the terminals on the rear of the receiver, or a bad voice coil or crossover in your speaker. If you re connect the speakers and it immediately cuts out, disconnect all speakers and reconnect one by one testing the receiver each time until your receiver shuts off or remains on with all wires connected and you've fixed the problem. If it cuts out, disconnect the problem speaker at the speaker and test again. If it stays on, problem is in the speaker, if it still cuts out, problem is in the wire. Hope this helps. If you need further help, post a comment and I can help you troubleshoot some more.
1.Check to see if the door is running correctly. A. Run the door down and pull the emergency release. See if the door will run easily by itself. 1. If it runs hard by hand try lubricating the rollers and hinges with silicone spray or some form of lubricant (not WD 40) 2. If the door is heavy and falls back to the ground, you probably have a spring issue (either broken or needs more tension) in this case call a professional door repair company in your area. B. If the door runs fine then check the up force on your operator (the box that hangs from the ceiling and reads Craftsman). If the light(s) on your operator go from front and/or back, the force adjustment screw is on the back of the operator. If the lights are on the sides of the operator then the force adjustment screw is on the right side (looking from the back of the operator and facing the garage door). Turn the light blue adjustment screw with the up arrow to a higher number.
