Hi I just bought a new 2600 on ebay the "Vader" and it doesn't work. the guy claimed it worked before shipping. when It is all pluged in and turned on all I get is a black screen, and if you wiggle the rf adaptor it will get blue and red snow on the screen, it seems to get power, and the unit seems to turn on but nothing shows up on the screen I've tried many different games and that doesn't help either, your help would be great
