All kinds of devices exhibit these problems. As Britt wrote, the caps have a limited lifetime. This is also true of the tantalum caps that make good replacements. While the tantalums eventually wear out also, they have a longer lifespan, and they don't leak corrosive goo when they die. I've also repaired three different VCRs which started behaving erratically by replacing the caps in the power supply unit. There's an outfit on the web that sells rebuild kits for the power supplies. One day the VCR just stops responding properly to the remote, or starts responding erratically. Usually there'll be one or two instances of unexpected behaviour before it goes completely.
