Faulty lot, 

MD 2 units just have a loose power port, 
they power on / load games but the connection keeps cutting out unless the power lead is held, should be a en easy soldier fix
one of these may not load games also

The md 2 with the rf lead attached doesnt show the pic, powers on but can tune it in

The MD 1 console powers on but cant get games to load

RF lead display a fuzzy / no picture

Md pads some buttons not replonding or little wire exposed
