Hi,
There are services available for repairing screen flex cables:

This YouTube video shows the process being done with a machine designed to replace flex cables.
Unfortunately the machine is really expensive, but the price of doing the job is cheaper than replacing a screen.
If you don’t have someone in your area that does it then you can search for “flex bonding service that has mail in information and ask for a quote.
Hope this helps
