Product review (4 stars): Tada! Works great, but the install is much harder than a screen replacement.
This item did the trick. The screen was showing lots of weird colored lines when opening and closing the lid, and sometimes would only show a good image when the screen was at a certain angle and I avoided bumping it. Since the device sees a LOT of open/close cycles in use, I assumed that a cable was going bad.

Install was tricky, but doable. As another reviewer noted, it's tricky to thread it through the hinge (tiny space) and I had trouble finding a video which explained THIS replacement as opposed to screen replacement (which I've already done once before). The difficulty in threading isn't the fault of this product, but I dinged one star for the lack of sticky stuff on the back of the cable to match the OEM one to hold it against the back of the lid. (Not a requirement, since the screen goes right over it easily.)
