I have 3 LG Flatron 775FT Monitors that click on then click off and will do it until you unplug it. I was told it was a resistor that needed to be replaced and was very common with that model. Can someone point me in the right direction?

Most probably on all your monitors faulty FBTs.
Very easy to check:
1. Unplug your monitor from power point.
2. Open the cabinet.
3. Unplug ultor plug from CRT.
4. Measure resistance from ultor plug to ground preferably
with digital multimeter.

If you don't have open circuit and your meter shows some resistance, your FBT 100% faulty.
And it is very common fault for these monitors.
