#1 Help to Config Screen Sep.

Just finish a support for a friend to set up the led screen bought 6 years ago (not from me). The original company and contact is gone away from him. But he find me in my Youtube channel. For most people, 6 years is a long time, anything can be changed. But for 7 years till now, I'm still there service my friends to do the same thing. This is a proud thing, right?
