I have a super sprint where the picture is fine but randomly some lines pop up that look like hedges or bricks somewhere on the screen. Usually they're no problem but sometimes these lines are 'walls' or invisible walls pop up. Sometimes you can get through the 'wall' and sometimes you can't.

Any idea what might cause this? Is it a dirty connector or pin somewhere? If it's a dirty/mis seated chip, where might that be - video/game logic/elsewhere?

Any help appreciated,
Andy
 
figured this one out. i ran a diagnostic test and turned out there was a bad RAM chip. swapped it out and the game works perfectly. Hope this helps someone.

in case anyone is interested... the RAM are 6116p-3 150ns chips
