MK121NTSC failure to launch

SEPT "17 I bought this kit the projects to work fine except for launching the the ball, it stays with the left side paddle regardless what level i pick. What triggers the launching of the ball ?

Is the unit setup for single player?

I can select any of the 4 levels but can’t get the ball to leave the left paddle

What happens when you press reset?

It goes to the 2 player mode I can move both paddles up or down, the left one has the ball on it and it moves up and down but i cant launch it off of the paddle

I will have to dig mine out and see what’s up.
