Street Fighter II Champion Edition Repair Logs
Symptom: No Sync and no audio
Board had been worked on before. An attempt was made at replacing the Z80A CPU.
Replaced a burnt 220 ohm surface mount resistor on the A board and a 74LS00 at location 3F on the B board to fix the sync problem. Removed the Z80 CPU and checked the traces. Socketed the Z80A chip and repaired three bad traces. Tested game.
