Re: Ribbon cut off ??

If it was cut off, you need to buy a new LCD ribbon cable. If it simply fell off then you can reattach it. Or if you are good at soldering you can try to solder wire by wire if it was cut.

Hopefully if your lucky it has a connector on each side and isn't soldered to the a PCB on one side.

If thats your problem you have no choice but to replace the board its soldered to or buy and solder a new ribbon cable onto it yourself.

If it has a connector on both sides the best thing to do is buy a new ribbon cable a reliable fix on these fragile connectors isn't very good. Especially in gigh flex areas like a laptops fold down screen where these cables get alot of abuse.

Normally the ends of those just push in at the LCD end.
Sometimes they are taped in place.

The other side has this little release thing that either pulls up (usually) or pops to the side (not seen often).

The normal kind:
You have to push the cable into the slot then while holding it in push the lock-bar thing down on both edges alternatly (push with tip of small screw driver) until it's all the way in on both sides.
Be careful.
Like zero room for mis-alignment because the contact areas are so thin in width.
