1943 Repair Logs
Symptom: Garbled player/enemy sprites
Problem would come and go with tapping/flexing of the board set. Flipped set over and isolated the problem down (by light tapping) to a custom surface mount chip on the ROM board. A closer inspection revealed 3 pins on the chip that were barely soldered at the factory. The connection broke loose resulting in the corruption. Repaired 3 bad solder connections on surface mount chip to fix the game.
