After months of anticipation I finally got my machine. I’m done setting it up and tonight was going to be our first date. I powered the machine up and immediately got a blinking screen. I switched wires, unplugged wires powered it on and off waited 30 seconds a minute. I did all I know how to do. Can anyone lend some help please. ---

Hey Kneepit, what do you mean with blinking? Does the whole screen blink?
