Broken screen or loose connector

A client gave in a laptop where the screen, about 2/3 down is cut off (image attached). It seems to me to be a physically broken screen, but I would like to rule out a broken connector. Can anyone based on the fact that the lines don't move when the screen is lowered or raised, no damage near the hinges, no noises coming from the hinges, confirm this? Or do I need to take apart the screen to make athourough diagnosis.

Would prefer not to as it takes a long time... but will do it if necessary. (But why do what is essentailly a waste?) What screen looks like

Hello,

If you haven't tried it yet, update the display driver from HP's website.  If that does not work, then proceed to the diagnosis.  Did the client indicate if the laptop was dropped or mishandled?

It might also be a Video RAM issue.  Does it have integrated Intel Graphics or ATI or Nvidia?  If intel, the RAM may be going bad.

Hope this helps.

What happens when you plug it into an external monitor?  If that works OK then your graphics onboard is OK.

Try booting from a Live Linux CD such as Ubuntu http://www.ubuntu.com/

Boot and get graphics screen showing.  If that is not OK (and I suspect it won't be) you're down to fault in screen or possibly a bad connector.  In either case dismantling will be necessary.

Maybe I wasn't clear enough, so I'll try again.

The screen is broken. The possibilities are A) physical, like a crack, etc in the screen itself. or B) the connector is damaged but the screen is fine. Is it possible, based on the symptoms mentioned in my first post with the original question to diagnose which one is broken, or is the only reliable way to diagnose is to disassemble and check?

Unplug , clean and reconnect the connector from the motherboard to the screen.

If that does not work then it is a screen issue.
 Not a crack but , the driver board that connect to the screen itself is bad. or the tiny connections are bad.

I don't think it is going to matter much even if the connector is broken.  Most laptop screens use a flat flexible wire cable into a compression-type connector.  If this is bad, it is doubtful that you can repair it anyway.  You would have to replace the entire cable assembly (you may not even be able to get a new one).  Also, the cable may be permanently attached to the display and to get a new cable, you will have to get a new display.  I sincerely doubt that you will visually see the problem.

If the laptop is somewhat old (3-4 years), I would consider trashing it, recovering what you can from the hard disk rather then trying to fix it.

I would venture to say that the display is bad.  Not a crack, but perhaps a bad set of drivers.  Either way, you will have to replace the display.

Installed the screen a couple days back. Besides some issues with a jammed battery (which covered some of the screws that needed to be removed to expose the screen), some cables still attached and necessitating some cramped repair work, the repair went smoothly. The screen works perfectly.
