well, I found that extreme cold was causing the player to not want to boot on some mornings. I've started bringing the player inside at night, and haven't had the problem since.

However, I'm still getting the problem where I boot it up, and it takes quite a while to start, and always says that there's no playlist loaded. When I load one up, it takes it a few seconds to get the list loaded (way more than it ever used to).

Could this be the result of a blown fuse on the permanent power wire?
