I fired up the ol' Mario Bros today and all the sprites are gone....

Any ideas? The title is gone as well.

Did the sprites get mad and leave?!

Help!
 
Video Board issue, or failing EPROMs I would believe. I haven't been able to get my board tested or in a cabinet, but I noticed a lot of EPROMs instead of just non programmable roms on their board unlike a good number of games use, so that would mean they are fragile around UV rays unless properly covered.

Make sure all those chips are seated properly in their correct sockets, even the slightest bit to the side and it causes video issues. This is with every game, my CPS-1 boards have a tendency to easily shift the roms and board sockets to cause sprite issues.
 
Okay. It's fixed. You are correct. I guess when I moved it over to the new cabinet, that's all the chips could take. I reseated them and they now work.
