Record Player Repair

Hello, I have been given a record player that is a bit like a sideboard, apparently it works and just needed a new head. I got a new head, but I still can’t get it to work. I can’t really take it to anyone to have a look at as it’s really heavy. Does anyone know anyone who could come and take a look? I suppose it’s a really easy job, I’m just too unknowledgeable! Thanks a lot,Fran
