While driving down to SiliCon on Friday afternoon, I got a call from the repair center to which I took the DVD/Sound system last week. The diagnosis: the amplifier is shot and needs to be replaced. (This would be consistent with the F61 error code, all right.) After credit for the $50 spent already, it will cost another $200 (about half of which is the cost of the replacement part while the rest is labor and tax). The woman at the repair center started to go on about how it would take several days to get the parts and that I shouldn't expect it back for a few days when I interrupted her: "I'm leaving for Oregon on Wednesday afternoon and won't be back until October 23rd. Will that be long enough?" She sounded relieved and said that would be okay.
