Are these radios with separate display lighting circuits?  Some radios have
the panel lights powered from the X relay and/or the vehicle lights, but the
radio itself is powered separately.  In these cases there's sometimes a
cartridge fuse in the back of the radio, right next to where the power
(usually a red wire) for the main radio function goes in.
