Help Wanted! Concert Radio is not working, display is lit on radio, but no letters.

I unplugged the amplifier in the trunk, and when I plugged it back together I got these faults:

5 Faults Found:

00850 - Control Output Active: Radio Amplifier
29-00 - Short to Ground

00668 - Supply Voltage Terminal 30
07-00 - Signal to Low

00852 - Loudspeaker(s): Front
29-00 - Short to Ground

00855 - Connection to CD changer
49-00 - No Communications

00856 - Radio Antenna
36-00 - Open Circuit

I have tried to clear the codes but they come right back
So far, I've checked the fuse (20amp) in the trunk(passenger side), it was fine.
I also checked the fuse (5 amp) on the back of the radio, it was fine too.
Connector to amplifier is firmly back on.

Suggestions anyone?

Thanks to tozoA8 for helping me so far.

For some reason the emails that I've sent you today they coming back, delivery problem.

You have two power going to the radio. One switched from the ignition and one 12v all the time. Check with the tester if you have any power by the radio.
