Dell D620 laptop has video issues that I can not diagnose

Question

I took a short video of the video problems I am having, you can see it here -> http://www.youtube.com/watch?v=43eNQy8oDt4

I tested the laptop in the BIOS menu, Ubuntu and XP safe mode and the problem was still there
Tried different resolutions and colors with no effect on the problem
I hooked up an external monitor and the video was fine.
Thought the problem might be in the connection to the monitor so I got replacement LCD and the problem is still there.
The problem seems to be consistent.

Maybe bad ribbon pins on the graphics card or a faulty GPU? When you replaced the LCD, did you also replace the breakout board?

	The only thing I replaced was the LCD itself. It's still using the same inverter as well. – evolvd Jul 23 '10 at 19:36
	In my opinion, the motherboard seems fine if external monitors are working. You may want to investigate into the breakout board and may want to buy a new housing for your LCD. Also in my opinion, it would be a good time to purchase a new laptop or have it replaced. – Steven Lu Jul 25 '10 at 18:01

After further reading online the problem seems to either be a failing motherboard or video cable.
