How to repair a screen senser fillament

I realize this may be partially attributed to language translation, but it's not clear from your question what it is you're looking for. Do you have a broken flex cable going to some sort of sensor mounted on the screen? If so, which sensor is it? How is it broken; is the cable itself damaged, or is it a connector issue?

Pictures are often worth a thousand words, so if you can add a photo of the damage you're concerned about, that would help.
