Question about Yamaha RX-V995 Receiver
All other functions work on the remote and the receiver. I think its something in the receiver that is not letting the volume knob to turn it up.
If this is a rotary encoder, when you normally turn it by hand to the left or right, it will feel like it moves slightly, but never fully rotates. This is not a potentiometer like the old days. It is an input to the display microprocessor IC(computer within your receiver) If the volume works normally from turning the knob by hand, the rotary encoder is fine. When you use the remote via infrared, there is an Infrared receiver in the receiver to pick up those signals and convey them to the display microprocessor. If all the other remote commands work OK, you can have two issues. One, the remote, for the volume is bad(the computer within the remote) or the display microprocessor IC itself, is bad. If you need more assistance, or would like to inquire about a repair, please visit my website at audioserviceclinic.com. You can contact me there. Thank you.

Remove the volume knob by pulling it straight out off of it's shaft. Use a dry cloth to clean off any visible crud and dust. Spray silicone lightly; the shaft and the shaft washer. Replace knob by aligning it by it's shape and work the silicone into the volume mechanism by twisting the knob a few time. Now try it with the remote.

SOURCE: 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.

Unfortunately, it sounds as if the encoder is broken. The encoder is a digital input which takes the place of a traditional volume control, and is what holds the volume knob in place and spins. Since it works fine with the remote, that means everything else is ok, but you will have to replace, or have a tech replace, the encoder itself.

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!!

Sounds like the volume control on zone 2 is your culpret. You should set up zone 2 to have a "fixed" output instead of "variable" it's in zone 2/3 setup. whats happening is you are overloading the volume control from the zone volume on the receiver and getting feedback to the receiver and shorting it out. What you do is put zone 2 to fixed output. set the vol control to 3/4 then adjust the vol to relatively loud and exit out of settings. this will be your max volume setting. Now, on to your problem.Unplug the receiver. There is an internal fuse that could have blown, not to likely but it's possible. You have to take the top off the receiver with a #1 phillips or a T10 torx they vary. It's about 7 screws, pop off the top and look from front to back, you will see 1 or 2 fuses near the AC plug port. Sometimes they are gray or white and you cannot visibly tell if it's bad. If you have a multimeter, set it tone resistance. Then put your leads on either side of the fuse, if you hear tone the fuse is ok. If not check your leads by touching them together and you will hear tone then test again. If you don't have tone, your fuse is bad. Radio Shack should stock the fuse you need. If you don't already know this, there are 2 Power switches for your unit. Front of receiver bottom left corner "Master Power" and normal Power switch "Main Power" check them both. If your fuses are good and power is good, you have bad transistors internally and it needs to go to service. check www.yamahausa.com support and service, and you can find the closest authorized service center to send it to. If you mail it out directly to the service center rather than taking it to a dealer, you will save some money and get it back faster. Lastly, pull your zone 2 volume control and look for black marks on it or white chalky substance. "oxidation". If you don't mind spending a little money on the system, hardwire the speakers thru and replace the volume control with an IR receiver. If you could control the zone from the zone by pointing the remote at the volume control you had an IR vol control. You really didn't need the vol part. Xantech or Proficient make good IR receivers that aren't too expensive and will keep this from happening again. If you need any more help, I am a Yamaha Dealer, let me know where your located and I can send you to a good service center. Just post a comment and I'll get you the info you need. Hope this helps
