Title
Universal Backlight Inverter
Introduction
I received a few monitors through an IT department. These are older monitors and it was deemed that any repair would be non-economical. Free, I take it:-) I checked two of the Dell monitors and noticed they did not have a backlight. I checked the power supply and could not find any faults in the obvious parts, i.e. Caps, fuses and resistors. Until I have my MOSFET tester build, I deferred troubleshooting the power supply. I decided this would be a great project to install one of the "Universal Backlight Inverters" available at an online auction site for ~$4.00. The process will be the same for any brand of LCD display. The difference will be the way the monitors are assembled and the layout of the power supply. I tried to keep this guide as generic as possible.
