I have a Sony str-de185 stereo receiver that I found used at a thrift store. It's worked fairly well for a couple of years, besides it cutting out a few times here or there. Now it's doing it much more frequently, and now it isn't coming back on by itself like is normally would. It stays powered up and everything functions as it's supposed to, but with no sound. It'll be working fine, then there's a quiet click/tick from the receiver and it goes silent. For the last couple days, a slight love tap on the top brought it back, but now even that isn't doing it. When it come on, I'll turn it off, and when I turn it back on, it has no sound again. All sources are good, and the speakers work fine, so I'm 100% sure it's a receiver issue. Where do I start?
