just been asked to look at a ps3 for a little boy next door his mom just brought it for him off ebay , it turns on ok but when i try to play a game or film i get error . cannot play this disc the region code is not correct

sounds like a ps3 that someone has been hacking around in
or
that the drive has went out in it
its happening more these days

thanks mate , it turns on fine and shows the game that is in the drive it comes up eg play need for speed , but when i click play the screen goes black and stays like it

sorry mate forgot to add i sorted the region code bit out it was set on usa , but now as i said it just goes black
