The volume knob on my rx-v1200 is hardly functional. Turn it to the right, and the volume jumps up and down within a short range. If you're lucky, it might track well and adjust properly, but this is so rare that the knob is almost useless.
I can only adjust the volume on the remote, and even that is now becoming difficult. All other remote functions seem to work fine, but the volume adjustment has to be held for a long time, and then the volume makes a fast adjustment. No individual "taps" for smaller adjustments.
Is this a common problem? A cheap/expensive fix? Something I could fix if I take it apart and replace faulty parts? Any input or direction would be great!

Re: volume knob quirks
If you know how to repair, then replace the volume control switch. it is a digital type/mechanical type of switch with silicone oil on it to prevent sudden turn of volume. if i were the repairman i can simply clean the contacts of the volume control and pour silicon oil again. but i really dont know in your area if they try to clean those.

Did the volume control get an impact? Could be internal damage to the digital control. Did it act up prior to this non-function, like volume went up on a down command or jump up or down when a slight turn was made? Thnose would reinforce a damaged volume control.
check ur speaker wires, try disconnect all wires from back of unit and then try to turn on unit .if it stays on whit no wires attached than u have short connection at speaker wires . if doesn`t come on then try to fasten screws at back of the unit , may sound like BS but if amp board don`t have good ground connection it can go in protection mode happened to me on RX-V592
It sounds like the volume control pod has gone bad and needs replaced (The knob shaft connects to the pod main body and the inside of the volume pod is what controls the rate of volume,If the inside becomes worn ,broken or dirty the volume will become erratic) Replace volume pod ! ..You may try cleaning by taking off the volume knob and getting a can of pressure air and blowing the dust out!
Please rate response!!
if you are not really that technical type that can make repairs then it will be very hard for you to replace it yourself. not hard to find the volume control, it is mounted on a board. you dismantle the board first then remove desolder the volume control. it think you can onyl get the parts from yamaha service.
just connect your subwoofer mono RCA to your amp sub single out rca connector. you do not need to megre all those 4terminals into one. in fact internal circuit of those 4rca are merging inside to one since the sub uses only a single amp. 4inputs was meant for sources with multiple sub out
