2010 backup camera not working

Hi, just got back from putting redone cap on my truck and now the back up camera doesn't work, they shouldn't have had to touch anything on the truck, called them and they said no, but they would check out for me if all connections are ok if I want, but I did that and all seems good....these things go with no warning or what???........sucks big time.....any help on this would be greatly appreciated thanks.

 

It is electronic. They can go without warning anytime...

 

Correct.... The camera itself is pretty cheap...can find on eBay for $25 to $80.

The rear mirror display is the more expensive part so hopefully it's just a bad camera which is a plug and play replacement

 

ok will get it checked out thanks for info.....will post back when I have it resolved......got kinda spoiled with It and want it back now!!
