If either one of pin shows a diode reading that is abl pin. The reason we use two multimeters is because flyback circuit internally have couple of high voltage diodes connected in series. If you have a schematic diagram or any monitor or television troubleshooting book, you will see that internal flyback diode are connected in series. By connecting two meters ouput from probe is around 24 VOLTS which is enough power to check flyback internal diodes. After you have determined abl pin, you can proceed to follow line and find bad components that cause contrast problem.

Television or tv flyback transformer generally have same design compare to monitor flyback. Whether it is a montblanc flyback transformer, rca, mitsubishi or sony flyback checking usually is same.
