Martial Champion Repair Logs
Symptom: Corrupt Graphics.
Character graphics and some scaling background graphics corrupt. Some graphics partially off screen.
Board passes initial self tests. Pushing down on the surface mount ICs had no effect.
Pushed the test button and ran the Mask ROM test. ROM 22K, 20K, 19K, 17K, 12K, and 10K were showing to be bad. These ROMs were connected to the surface mount custom IC 055673 at location 14K. Resoldered the chip to fix the corrupt graphics.
