Hi Larry, thanks for that - yeah definitely seems to be the key contacts but I won't fiddle around with it or attempt to open it.
I have contacted the seller who is arranging a courier to collect the keyboard again, hopefully on Monday. He will not issue a refund though as he says the keyboard was fine when it left him and he doesn't have the money in his bank. He said I should put a claim in with paypal - I have done this and have all conversations via email if needs be.
I just hope I get my money refunded asap and my quest continues!! I really am gutted because I was looking forward all week to getting the keyboard. I was a little disappointed when I opened the bubble wrap as it hadn't been cleaned, had a few scuff marks and stank of smoke!!!! Wasn't too worried about that though as long as it worked and would have cleaned it up as best I could myself.........unfortunately all plans are cancelled when the bloody keys don't work!!
