have heard that the ribbons can be replaced but it needs specialized equipment like Z axis tape (this is for the lines only/blank problem, and a subset of those) but the glass is normally the cause.
I have a very expensive camera here with this fault, internal cable went bad but its a special sort of tape more expensive than standard Z axis as used in ipad repairs, chibitronics kits etc.
This works fine if the alignment is spot on for relatively large pitch connectors however like calculator panels!
If you have a good ribbon and screen then try https://www.adafruit.com/product/1656 might do the trick but alignment needs to be finer than a human hair.
Best done under a microscope or better still screen+camera.
