Kenwood VR-507 Receiver Starts Clicking at Random and Audio Cuts Off
Ive had this receiver for like forever. Recently, it started doing this clicking thing. It clearly sounds like some kind of relay and seems to happen at random. Some times it goes for 4 - 5 hours (after turning it on) w/o happening and other times its after only 10 minutes.
Some times it click 6 - 8 times a second for a couple seconds and other times its maybe once a second for 5 mins. The audio cuts out while this is happening.
I first thought it might be a heat issue, so I blew the thing out and stuck a fan blowing on it. This changed nothing.
Interestingly enough though, I realized its the SPDIF In audio that cuts out. When using the analog input on the front, the audio doesnt drop. But the clicking is quite loud anyway.
Anyone have any diagnostic/repair suggestions?
