I have a JVC RX7000-V receiver I bought years ago. The thing has worked great until a few days ago when the volume got stuck at one volume when I turned it on. If I turn the volume knob or volume on the remote, it does nothing until I get to 0 then it turns off. If I turn it to 1 or higher, it just goes back to the same loud volume (volume number 1-70+ still have same level of volume). I tried unplugging it for a while as well as playing with the setting from cd, tv, dvd, etc. Same difference on all. Anybody ever seen this happen on a receiver where the volume just gets stuck at one level?
