Touch screen not working after replacement
I recently replaced my friends screen after her autistic son shattered it. The first replacement, the touch screen wouldn’t work. I figured possibly faulty screen. I ordered a second screen and the same thing happens. The wording on the screen jumps around and it won’t recognize touch. There are times the number on the passcode get hit but I didn’t touch the screen. I have checked the connections multiple times and everything seems connected correctly. Could something else be damaged that I can’t see? Thanks for your help!
