Re: loud noise when volume is turned up
OK, if it feels like it relates to the turning of the control, then the vol control may be noisy and will need a spray with contact cleaner lubricant. Do you think you can do this, I can talk you through it. If not, a repair man or someone with electronic experience could do it for you.

Doesn't sound like a fuse. They don't fix themselves when you reach 75%.
Try shaking the volume knob while in the 30-50% range and/or try (with the power off) rotating the volume knob numerous times from 0% to 100%. If when you plug it back in it responds ANY differently, you might have a bad volume potentiometer. If when you shake the knob you hear static or intermittent sound, you have a bad volume pot.
The only other thing I can think of is that the wiper of the volume pot is not in contact with the windings inside the pot until you reach the 75% mark. When the volume comes on at 75%, does it start off kind of "static" then come in loud and clear? Also try this.... adjust the volume pot to 74% (or when the sound just begins to come on). At this point shake the knob. If you hear static, replace the volume pot.
Unplugging it when still on shouldn't cause any damage... in fact it probably hasn't considering it works at 75% plus.
You could have done a very slow damage to the Yamaha if your UPS was not a pure sine wave type ( on line UPS ). Most of the UPS we get are called Off line type and are far cheaper than the On line pure sine wave type. The out put of the Off line type UPS is not a sine wave ( the natural waveform of AC voltage ) and strains the Power supply circuit of any device connected to it. Now if the humming sound is the same irrespective of the volume position, it is a power supply problem. You might be having a leaky rectifier diode or capacitor. First change the diodes and see if its ok then change the main filter capacitors too.
Since no specific model number is provided I can only offer generic advice.
Static noise can be due to radiated noise in the environment leaking into cabling or it could be a dirty mechanical connection or control like a volume or balance knob or an oxidized contact that you rarely use, like a Tape Monitor. I'd turn the unit off and reseat every RCA connector with a twisting motion, rotate and flip every switch throughout its travel a number of times and see what happens.
usually, it is background noise. Scratchy background noise. Gets worse the louder I turn up the volume. I ran a test on all the channels and it seemed to be the subwoofer channel. I've unpluged the subwoofer but that didn't help. I have also noticed that my receiver doesn't turn up nearly as loud as it used. I usually watch DVDs at a volume level of about 15 on my Denon and that's quite loud. But now, 15 isn't that loud at all. I went to Best Buy where I bought all of this equipment and they immediatly told me it was suge protector issue and wanted to sell me a high-end surge protector. Perhaps they are right but not sure why it began rather suddenly. Probably not helping you much.
hi. i have a sony amplifier. i plug the speakers in like normal. i turn it on and the right side speeker works fine. but you half to crank it up all the way just to barely hear the left speeker. we switched speakers and its still the same effect. we think its the amp itself. we tried our balance settings. it was fine. but right now its just playing one speaker louder then the left one. can anyone help me?
I think it's a grounding problem. Actually, it's a necessity for all audio-video equipments to get grounded properly. If you don't have a ground connection in your AC plug, your receiver will collect more and more static electricity. As a matter of fact, it decreases the sound quality that you can get from your equipment. I think that the effect of your reaction (slapping the receiver) isn't coincidental. When you touch any metal surface on your receiver (even while slapping) you condact the static electricity to the ground.
I've had a same sort of problem with my receiver. Especially when I connected my laptop computer to the receiver, I heard an annoying distorted sound from the speakers. I found out that it was ground loop, which occurs when the negative (common) signal of the source coincides with the one of the receiver's. As a solution, I grounded my amp, changed all wires with new and shielded ones, and purchased an AC filter. Then, I got rid of the noise. I have to say that the AC filter (Belkin Pure AV Surge Protector, it also includes an AC signal filter)benefited me the most.
