This answer is only backed up by the answerer personal experience, with no explanation provided.

if it was my customer i would dismantle the screen on the spot and use a spare screen (which i have plenty of in stock) to prove my point. as a reference for why i believe this screen needs replacement, it is because i currently have one in the shop in an identical condition and resolve in the way i am describing.

I'm not sure what to do at this point, because I know that I've met problems that are fixed by replacing parts, but I can't explain what's wrong.

Is this kind of answer acceptable here?

Additional question:

is a VLQ flag for that answer a right thing to do?
