I had a monitor that would show the little green light which meant it was on but would not show a post screen. When I fully seated the loose power in the back the post screen came back. For some reason it had enough power to light the little light but not the back light.
But, my monitor is not a flat screen type. It is also like a tv screen.. Old modern of a computer monitor.. But thanks for your info. I tried to apply that...
