If it does not follow then probably the first thing I would check is the cable from the MB to the LCD.
addoraa, I just hooked the laptop to an external monitor and the problem did NOT follow/appear on the external's screen. I'll have to look for that video on how to replace the LCD screen. It should show me how to get to the cable connection.
Thanks addoraa for the suggestion. It helped narrow it down.
