Zener diode is a diode which is used in its break down region. The diode is kept reverse biased in a circuit, and so it does not allow current to pass until the voltage is greater than the breakdown voltage of the zener.
Whenever the zener diode shorted it will cause no power problem in the Monitor. The real challenge is not about troubleshooting or finding this shorted zener diode, it was the voltage that i could not get from electronic suppliers. It was rated as 200V and if according to Philip ECG Master replacement Guide Book, it was the highest voltage in the zener diode category.
