Replaced Battery Now Radio Is Not Working

[togan]

I have a 2002 Sierra. After replacing the battery, the radio is dead. I checked both fuses and they are good. Any ideas? thanks.

Hi,
You may have the "Theftlock" radio feature. Check your manual or enter theftlock in this forum's search archive.

Thanks. I considered the TheftLock..., the letters LOC are not displayed. The unit is fried. Funny, but nothing else was effected. Thanks again, togan.

did you check the fuse? i hope the fuse would have protected it.

Thanks to all replies. The fuses were good. Somehow the radio got fried. Plugged in a new radio and it worked fine. Tried the old one again and nothing. Expensive lesson, but still don't know why it happened.
