After changing display, there are problems

Well I successfully changed display to some from Chinese market one, but after changing display there are some problems now:

  1. Sometimes you have to press power button multiple times to wake up display
  2. Sometimes when someone is calling you, display won't react to touches and you can not pickup call.

What could be causing this?

@playandwin from what you are describing, it sounds like a bad display/touch screen assembly. Of course, always double check your work ensuring all the cables are properly seated and the connectors are in good condition. Also try a reset so to rule out any software issue. If you ruled all that out, you know its the display assembly. Can’t repair that but would need another replacement.
