if you are confident enough to take the unit apart you can remove the rubber button pad and clean the surface of the circuit board
with q tips and reassemble the unit. They get dirty over time.
Most units have screws at the bottom back or in the battery compartment. Be careful not to tear the rubber contacts(pad)
It thinks have headphones inserted. Do you? Remove them.
DID you have them plugged in just prior to this problem? If so Turn the volume down and insert and remove the headphone plug a number of times to wear off the probbaly oxide build-up on the normally closed contacts.
These amplifiers have a fuse link inside of the main transformer. If you want to, you can open the unit up and see if you have the main power into the transformer. Then see if you have any voltage on the secondary of the transformer, if not then the internal fuse has opened (usually due to heat). The tranformer will need to be replaced. Yamaha will not sell parts to consumers, so you may need to take it to a local repair shop for repairs.
I hope this information allows you to resolve this issue. If you need further assistance please comment to this post and I will try to help you further. Thanks for using FixYa asnowman
The part number is V2465500 Button case RXV595. This will fit the RX-V995. I ordered and replaced my own recently.
You can order it through Vance Baldwin, Herman's Electronics or Partsearch.com or Yamaha Parts Dept.
Cost is approx $10 plus shipping.
Note: The is one "hidden" screw retaining the button case that goes thru the circuit board for the front panel from inside the unit. You will need an offset phillips screwdriver to get to it. Be patient and good luck.
Remove the small screw in the battery compartment then put the long edge of a kitchen knife in the groove & twist. The case will snap open at that point then work your way around until it parts. Clean the contacts inside with Isopropyl alcohol & that should solve your problem.
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.
Yes, there are relay type switches associated with those outputs. Your RX-V1 is not dying.
Just plug a pin plug in and out of the dead channel to bump the switch. You will hear the speaker
come on. If it doesn't come on,do the plug jack in an out of the pre out again. It will come on.
You can use the test tone to check all channels and rebalance volume levels. You are making the
pre out connect to its power amp. It seems the problem got better when activating those switches. Most likely a cleaning issue. You can also jump the mains and center, and there is also
a modification to jump all channels. I bought my RX-V1 very cheap because of this and love it.
Of course outboard power amp would solve all, but getting this reciever to connect to it's own
power amp has been thrilling as far as bang for the buck. I do use the front effects also, and like
them. It may seem like a pain, but it is worth it to get those channels going.
