When I turn the volume up on the receiver past 1/4 while listening to music, the receiver will click and either completely shut down (meaning no more clock and unplugging is required to turn it back on) or it will turn off and blink (similar to what happens after a power outage). It will also do this while watching a movie for an extended period of time; leading me to believe it is overheating or there is a short somewhere.

Re: Receiver Shorting Out?
The power supply regulator is bad. it a bad regulator ic erroe transistor or even a bad capacitor. if you have the proper equipment and know how to troubleshoot solid state electronics, you should have No problem finding this fault. If your not trained to repair electronics, most likly this set will not be worth repairing or spending any money one.

You would have to have a mini-plug (headphone) to RCA cable and connect the headphone jack to one of the rca inputs on the receiver. Make sure that the volume on the laptop isn't turned up too loud, or you may over-drive the receiver amp and cause it to shut down.
how are your four outside speakers hooked up? If you have four speakers hooked up to only two output channels on the receiver, the receiver is sensing a short and shutting down to avoid damage to the amp.
Sounds like the music amplifier is different to the tuner audio amp. The music amplifier is now looking at an unbalanced impedance which is less than it should be. Therefore the output chip of the music amp has more current through it than it wants so it gets hot and shuts down.Put a four ohm wirewound resistor ( from Radio Shack ) in series with each surround speaker to reduce the current flow through the amplifier output.
check your power supply to make sure the correct amps and volts are there. check your speakers to verify the correct ohms for the receiver. if the ohms are to big you will shut down because it overdraws on the receiver.
When you turn it up do you hear the relay or a clicking sound, then you turn it on and it comes back below the +2db?
Try unplugging All the speaker wires from the unit. Turn on the unit and listen for the click. after the click, turn it up past the 2+ db mark and see if you hear it click or shut down. If it did not click off, then suspect a shorted crossover on one of your speakers. 2nd test is to plug in One speaker, and test it at high volume, it will not harm it. If it shuts off disconnect that speaker and try another. Only one at a time. If it works at high volume, you need to isolate one of your speakers and i bet it has a shorted crossover that has been cooked. P.S. If one is bad, suspect they will fail at a later date. If they all fail, use a friends speaker and try it before sending it to a repair shop.
P.S. i found one on ebay i think you can get for under $100 bucks in the box.
Does it display any message like "Protect" or something similar? Do you hear a relay click on then off?
Did the amp just not power up one day or did it stop working while you were listening to it? Finally, do you have teenage kids who might have been listening to your receiver and would have "neglected" to tell you that after listening to their music it suddenly stopped working?
It could be an internal fuse but chances are its something that requires a technician to repair (like the output transistors).
Since a CD/DVD player is a digital device, it can be susceptible to such things as power line glitches, interference from other digital equipment and even the ignition interference from nearby passing cars. With older analog gear, you might get a short burst of static, whereas it can completely shut down a digital device sometimes (glitches interrupt its internal program). Sadly, there's nothing you can do about this except plugging the unit into a power line conditioner. You might try jiggling the connecting cables (especially the audio cable), but it sounds more like a random glitch since you can use your remote to fix it. They haven't yet worked out all the bugs in digital equipment, unfortunately. It's also possible that a defect in the DVD player was not caught at the factory during final test.
There is a problem with the receiver that is allowing DC voltage to get to the output amp section. This is detected and the protection circuit shuts down the receiver. Yamaha uses coupling capacitors between sections to prevent this. If one of these is defective, it would explain your symptom. This should be a relatively simple repair for a repair shop. Expect $10-$25 for parts plus the local labor rate.
