Hello members,
I recently picked up an Outrun game. I installed a new switcher, and I get a solid 5V at the harness. When connected, the screen flickers constantly and I hear "check point" and various other speech. A check of the voltage at ROMs and CPU shows a steady 4.35. I did get the test screen comes up briefly. The ROMs and RAMs all tested GOOD. Does anyone know what on an Outrun PCB, or any PCB for that matter, would draw the power away from the Rom's like that? I imagine I need to get to a solid 5V on the ROM's before I can figure anything else out. Any help would be greatly appreciated.
Thanks in advance,
Shawn
