Repairing my Rock Candy Keyboard after the Batteries Leaked.

Had this keyboard a while now but it's barely seen any use in that time.

A while ago I dug it out with the intention to use it day to day but found the batteries had leaked inside it.
Changing them didn't work so it sat in storage for a while longer until recently I had the idea to finally try and fix it properly.

As is always the case when I set about a 'quick' project it ends up being an all day job but nevermind, this is how I managed it.
