Yamaha RAV238 Remote Volume Buttons Inoperative Everything Else is Fine
Hi, this AVR (Yamaha RX-V1400) got moved upstairs and for some reason the volume buttons on the remote RAV238 stopped sending to the AVR. Every other button I touch does send (the red light in the upper left shines when a key is pressed). It's just the volume up / down (press them, no red light) that are the only keys not working.
ANSWERS:
Both of these descriptions are correct. I would only add that YOU GOTTA BEIEVE. It is very difficult to pry this thing apart. I found that starting near the bottom, along the long edge, and prying with a thin but wide flat screwdriver worked. Once the first latch pops out, slide the blade up until you can feel the next one holding and pry again - much easier.
I was in the Same boat and knew the remote was done so opened the back and moved different pads over the the volume tab and it worked. The pads that I didn't use more or less the same size and cut the square out and replaced the good one with the bad one. It works and saves you having to find a new remote.
"System power" button needed hard pressing even after cleaning. So I cut small piece of aluminum foil and placed it between circuit and pad. Now button works as normal. Well... who knows how long it will work but now it works 8^)
This worked GREAT. I would only add that alcohol wasn't sufficient to clean it in my case. Although the contacts "looked" clean they didn't work... I could reposition any other key over the pc board position for the volume and it would work. So it was the carbon film on the bottom of the button causing my problem. I tried cleaning them with 1500 grit emery paper and still nothing. I tried the aluminum foil trick. That worked but I was concerned about what sort of unwanted contact it might make if it slipped after I started using it. So in desperation I wet the emery paper in alcohol and "wet sanded" the carbon film. THAT WORKED!... Now it's like new. Thanks for your info on getting the thing open and the overall approach!
