So I was commenting in the thread about screen quality...but I feel this might be a separate issue. I’ve been having noise issues on my screen. I resoldered the wires a hundred different ways and still had the same problem. I decided to plug the button board in and mess with it and it kind of fixed the issue. Can anyone tell me why this might be happening and if it is normal?

Almost all the composite screens i used whether from Gearbest, Banggood, Ali, or Amazon are prone to noise and interference.
