The backlight connection to the MOBO is probably loose.

I check the back light connection to the mobo and it was not loose; however, I decide to order the Video cable and when I installed the new one, the monitor did funtion correctly. Your advise leadme to think that the cable was the problem and not the monitor. Thank you.
