Bad display on Dell Latitude c600 - need sugestion from a video recording

[Green/Electric]

here's the video:

I need advice/sugestion to know what part might be bad, Is the inverter or the flex cable or what else?
I was opening and closing the lid like a normal laptop would but without having the screws for the hinges so i believe the flex cable pulled in some wrongfuly way. I did reinsert the flex cable but this time nothing got fixed. I have 2 spare flex cables and 2 inverters for this specific laptop model latitude c600.

You need to be careful with the flex cable. Some tiny speck of anything can cause mishaps. check the socket of the cable was well.
