Please help camera problems!!!?

Okay, I was using my little sisters camera when all of a sudden it went blank, like the back light was still on but no picture. So I thought it went dead, so I went and put it on charge. It still wouldn't come on. Then I took out the battery then put it back in where the back light is off. Still won't come on. I still have it on charge but I have no clue what to do. Help!! Or I am dead. Seriously!
