Laptop faulty screen diagnosis?

[The Soulman]

The wive's laptop (hp elitebook 8460p) developed a failure in the displayed image.
I've re-seated the screen cable but no change, also wiggling the cable doesn't change things.

At the moment I want to know what the cause could be:

1) something on the motherboard (i.e. laptop is toast)
2) the screen cable and/or screen itself (something that could be replaced)
3) something I didn't think of.

Anyone guesses based on the attached pic?

That's problem with LCD panel.

you can exclude GPU if the screen has same lines in different graphic modes
9 year old laptop, one of the worst screens on the market when introduced, you finally have an excuse to upgrade
