Recently I had 3 consoles shipped to me from Japan. One Duo, and two of the white CD consoles (forget the model name). Anyway, they were complete with everything - one even came boxed. I tested each one and they worked fine here in NY with both cds and cards. I shipped them back to MN to be sold and when they were tested there not ONE of them powered up. I swear to got they worked when I had them, the box wasnt damaged in shipping or anything either - it seems wierd to me that not one of them works. I've tried using different power supplies but it has no effect. Any Suggestions???
