Re: HP 1955 Monitor Repair Guide

I have one of these monitors and I am finding there is a buzzing coming from the inverter board. Near the entry of the 110v power supply. It could be coming from the transformer for the mains power, or the caps that are near the entry of the 110v. Does anyone have a part number for a replacement transformer? The one for the mains power, not the ones for each backlight supply.
