Everything was working fine until I took the boards out to check for the size fit of the NVRAM i was about to install. When I realized I had the wrong size I slid the boards back into the cage and now I get this...

I have since got the correct NVRAM and it is now saving high scores correctly. Maybe I loosened a rom when taking it out. My question is can anyone tell which one it might be just by seeing the picture?

My best guess is that it's somewhere on the video PCB. After that I'm not sure.

Thanks

Try reseating the 09xx custom. That guy handles the road graphics and it's curves as it goes into the horizon.
 
Thanks guys. I simply pushed down on a few of the bigger IC's. I saw in the supplemental manual that the raceway graphics where in the 2 section. Now it works fine. Thanks.

Thanks again Dick for bring this board back to life. My 6yo loves it. He's better than me.
