magic 2 chip problems

[albat1939]

I just recived a playstation 2 magic 2 premoded unit. It powers up but does not show any picture or sound. It dosen't even switch over when I put a RFU adaptor on. Is thier somthing i'm not doing. I can't contact the company I bought it from because they "are moving thier offices and cannot recieve e-chat or phone calls" They say they are responding to e-mail but it's been a week. I think I might be SCREWED!
