When I originally purchased my Tailgunner, the horizontal deflection transistors connector and the monitor's circuit board had visible damage. This was caused by a bad deflection transistor combined with the circuit breakers on the game's power supply being bypassed by a previous owner. The severe damage occurred because the circuit breaker was not able to cut power to the monitor.
The pictures below show the damage to the monitor and the bypassed circuit breakers on the power supply.
