As far as repairs go, this one is almost trivial, IF the sled is not currently installed in a vehicle. Any 14 year old aspiring scientist could probably handle it (standard nerd skills).

If the sled is wired firmly into a vehicle, then repair is trickier, but most any decent car audio shop SHOULD be able to handle it.

If you're anywhere near Ottawa Ontario, stop in and I'll fix it.
