Flickering Horizontal Lines — Packard Bell Easynote LJ65

Can anyone help me in determining what may be causing this? A friend gave it to me to fix, and while my suspicions rest on the possibility of it being a loose ribbon cable linking the LCD display to the motherboard I’m wary of dismantling the casing for fear of causing further damage. At least if I have as definite an idea of the cause, I can inform the technician and not be charged over what I should be.

+ Some points to note:

• I was informed it had *NOT* been dropped (which I don’t believe, although the computer is working as good as new save for the flickering)

• No flickering issue when connected to an external monitor or TV via HDMI (thus spurring my theory that the cause is likely a loose lead/wire/ribbon within the back of the LCD panel itself)
