The part # did nothing for me in a Google search. For an RAZ, I came up with P04704383AH for a Mopar part #.
It would say 'Anti-Theft' on the faceplate if it had it and the display would at least light up with dashes.
The radio is on the CCD bus, but doesn't rely on it for power up.
Do the dash illumination lights work? Do they dim with the control? I have had fully dim dash lamps keep the radio display dark.
If you don't see the faint orange filaments of the VFD tube lit, it may be a failed tube or power supply? The VFD uses about 22 volts to light the screen characters.
I believe that the driver IC for the display is under the tube. Check solder joints.
There is an article on the RAZ, but a 2002 probably has some differences than a 1998:

Unless it is grossly overcharging, I think that you are just getting failed radios. D106 should hold the filament voltage to 2.38v. Note: This 1995 model may not be exactly like your radio.
