The game keeps resetting: the display stays blank and the lamps blink. The 5 V supply at the CPU and display controller reads normal.

Game keeps resetting with blank display and blinking lamps: faulty 6264 RAM

Cause: A faulty 6264 RAM chip on the CPU board.

Checks

• Check 5 V at the CPU and the DMD controller; this system resets if it is much outside 4.95 to 5.05 V.
• Reseat the power connectors (CN2 on the CPU/sound board and J16 on the power driver board) and the ribbon cables.
• Press on the game ROM and the 6264 RAM to check for poor socket contact, and look for battery corrosion.

Fix

• Replace the 6264 RAM.

Systems

• Sega/Stern Whitestar
