I’ve repaired these numerous times but it all boils down to the condition of ribbon.
I have done it several ways. I’ll list them: You can scrape the ribbon to expose the metal . Then use trace repair on it. It’s made up of like silver paste with an adhesive mixed in. [br]
I just looked it up . It’s called a silver pen
You can hard wire it. Get like 18 or 20 gauge wire and solder them. [br]
I’ll leave it there and that should do it. The other methods are complex and too hard to explain. [br]
Good-luck and hope this helps
