Found out that the little slo-blo fuses go bad on these. Cheap and easy fix if you know how to solder.

Fuse:
subminiature
750mA (some say 500mA)
125v

Easy to check with a ohm meter. A good fuse should register less than 50-100 ohms. Infinite ohms equals bad fuse... so replace.

I will post a DIY pictorial when I get my fuse today and solder it in.

Cheers!

PS: If your blue lights do NOT come on when the unit is in the dock, you probably have a blown fuse. The remote will still show it is charging, when, in fact, it is NOT.
