Hello.

When I warmed up DAYTONA USA 2 last week, it was found that there was a problem with the MODEL3, which caused the in-game or attract mode 3d gameplay graphics disappear and turn blank blue. Today I took the time to remove my DIRT DEVIL mobo which is also Step 2.1 for troubleshooting. It turned out that the CPU BOARD on the middle layer of MODEL3 was broken.But it was strange, all the ICs show good under CPU TEST.However when I changed the CPU board instead of the broken one,everything ran perfectly.

Which part was damage of the MODEL 3 CPU board still unclear, if someone knows the reason, please comment.

Thank
