I just bought a 1972 Magnavox Odyssey, finally, and I plug it in and there's no picture. I am using a universal 9v A/C adaptor to hook the system up, but there's no picture. I don't know what I am doing wrong. I tried setting it to channel 3 or 4, but nada.
I assume it's just supposed to have a picture when you plug it in? I don't see an on/off switch.
