Has anyone had a malfunctioning Nomad AND successfully repaired it? My unit simply doesn't want to "boot up". The backlight comes on, and there are a few static crackles from the speaker, but it never gets up and runs. The cartridge connector has been cleaned quite a bit, but to no avail.

Does this sound familiar? Any tips for things to look for? Common faults in Nomad hardware?

BTW, this is running on AC input, so it's not a battery issue.

Thanks!
