The only possible installation problem could be the illumination wire on the head unit. If this is hooked to a 12 lead it would dim the backlight. Try disconnecting the orange wire if it has one(I'm not sure if the 7834 had a dimmer lead). If that doesn't fix it the head unit will have to be serviced.

I Just Purchased a Cavalier with an Alpine CDM 7861 stereo. no owner manual or slides to remove the slide out head. how do I remove without damaging the stereo?

If you go to an car audio install shop they have tons of leftover slide removal tools. Just ask them for a pair. The nice shops will just give them to you without charging.

How do i set the time?

Not sure if you have tried this yet or not but try turning the radio off and then holding down one of the buttons for a couple secs to set the time. I have to set mine with the radio off and thought maybe you hadn't tried that...
