Radio won't go on after battery disconnect

[healthservices]

Newbie here, love this forum!

99 Boxster


I was doing some work on the door panels and did not want the air bag light to code up so I disconnected the battery. As it turned out, the airbag is in the door and not the door panel.

Reconnect the battery and...

nothing. no display. I push the power button and nothing. I push the eject and the cd comes out. I insert a cd and it goes in.

Although crappy sound the radio worked and the display worked prior to battery disconnection.

I cannot put in a code as I see no display.

little help?

Thanks

Allen
