Morning Ladies!

I hope I have this in the right spot... couldn't find any "electrical" type threads anywhere...

I have an Angel Care Sound and Movement baby monitor(the one with the movement pads) and recently the hand piece has stopped charging in the cradle thing-a-me. I thought perhaps it could be that the batteries needed replacing, which I did (with another set of rechargables, obviously) but it's still not working.
Has anyone else had this problem? If you did how did you fix it? Or is it a gonner?
Its only as old as DS (maybe a couple months older as you tend to buy things in prep for the little buggers!) so I'm going to be totally PO'ed if it's shat the tin.

Thanks for any help, or suggestions! xx
