Did a toddler break my speakers?

I have a pair of vintage Bose 501 speakers that have worked great for the past five years. They are connected to a vintage Yamaha CR-820 receiver. A while ago, my favorite toddler pushed all the buttons on the receiver and the speakers stopped working. She came over again, pushed a bunch of buttons and it started working again. Next time: bunch of pushes, stopped. Now no button pushing seems to matter... is it broken?

In between button-pushing sessions, the speakers make a random, horrible sound: like a repetitive, scratchy, high pitched squeal.
The only way I can get them to work and it's not always, is to send music to it, turn the volume up all the way, wait about a minute until I hear the faint sound of the music, turn it down just a little. At this point there will be weird vibrations and horrible sounding squeals until the music takes over. Then it's fine. I can stop playing the music for about 30 minutes, turn it back on and it works. But if I stop for an hour or more, the speakers won't play and I can't do the turn-the-volume-up trick. I have to power off the speakers so they don't randomly squeal in the middle of the night and wait several days -- it seems -- before it'll work again.
Anyone have any ideas as to what's going on?
