This started 3 months ago. At first there was only one horizontal pixelated line on the top.
Now, there is one at the bottom. Below the bottom line I can see some of the top portion of my display (I know it sounds kind of weird, but I will attach some pics). The lines are rhythmic, they appear for a second and then disappear.
After 3 seconds it comes back. The flickering slows down after sometime. When the screen flickers, there is also a small jump.
It's not a driver error as it even shows in the BIOS and no problem when I hook up an external monitor. I opened the screen and checked the cables. Nothing seems wrong there, I mean no wear and tears, no blackening etc. So is the display cable faulty or my LCD?

That means it is a hardware issue. Things to look at.
Cable that connects motherboard to LCD is pinched, damaged, etc. Replace this cable.
Motherboard has sustained liquid damage, possibly near connector where LCD plugs into motherboard. Cleaning corrosion off with alcohol will help for a while but replacing corroded components is the only permanent solution.
LCD screen itself is going bad, replace LCD.
If your laptop is the rare type if an MXM or other removeable graphics card, you can try reseating or replacing it.
Other issue with motherboard, replace motherboard.
Display cable issues tend to go away or change if the laptop lid is moved, so if this is not happening it is more likely a liquid damage, LCD or motherboard issue.
