I have about 60 Hi8 and regular 8mm tapes I can't play

I have about 60 Hi8 and regular 8mm camcorder tapes that I can't get to play. They were recorded using a Sony Handycam DCR-TRV130 Digital-8 camcorder that I bought brand new in 2001. That camcorder was stolen in 2008 and I got a used Sony video Hi8 Handycam Vision CCD-TRV68 from a friend of mine but they won't play on it. All I get is a blue screen or white fuzz on the screen and static noise. The counter on the display is running, so it seems like there is still video on the tape, but I don't know why I can't see it. I have a lot of memories on those tapes that I would like to transfer to DVD. I have no reason to belive that all 60+ of my tapes have been damaged or erased. Does anyone know how I can get my tapes to play? Do I have to buy another TRV-130? If anyone has any help at all, it would be appreciated very much. Thank you. Chris
