Expansion Module #1 Problem

[Sam9938]

Ok I need some serious help. Got a coleco and the games I put into it run fine and play great but the expansion #1, when I put atari games into it it displays them at the wrong horizontal or vertical sync level, half the game is on top of the screen and half on the bottom and it just flickers like that type of thing. It is different for each game. I noticed that when I move the joystick when playing it flickers and shakes a little worse while a direction is pressed. buttons from the controller work fine and the games play, just cant see them really, any help would be great, thanks.

 

Also, if anyone knows where I can find a schematic that would be helpful too

 

 

I found that if I press on the board of the expansion to the top left a little the picture shifts slightly.
