I think this problem is a result of overactive overload protection circuits which do not reset fast enough. I had this problem on my RX V1, the channels would eventually come back on by themselves after a couple of days/weeks. I found that simply plugging an RCA patch cord into the preamp output of the channel and plugging the other end to a false input would reset it and the channel would come back on again. I had to do this about four or five times a year with one of the channels, particularly the surround channels.
Yamaha Rx-V1 Channel Drop Out
Wanted to know if anyone else has experienced/is experiencing the famed "channel drop out," which is very common with the V1. Because my V1 is not under warranty, it was just cost-prohibitive to have the entire video board replaced - so instead, I am having the rear RCA jack field, which is subject to the problem replaced. Has anyone else gone this route and had success/failure? Any feedback would be most appreciated.
