Hi,
I recently bought a playstation from ebay for my 2 kids and am trying to hook it up and having problems. When I plug everthing in, it won't work. I did have it going on another tv set, but I have a digital cable box for one tv and have tried every possible combination to plug it in with no results. Can anyone help? Do I possibly need some kind of adaptor?

I have never owned one before or set one up, so the simpler, the better- i'm at a loss

Thanks
