Digitizer/Touch does not work after replacement kit installed
A couple of weeks ago I ordered and received a replacement kit (screen + digitizer) for my S4 Mini. After correct installation it shoiwed two problems :
- Screen lookd like an old TV with static
- Did not respond to any touch
- Rest of phone worked ok
I ordered a new LCD+digitizer kit and installed it without problems. Now the screen works, edisplay is OK but the digitizer does not work.
Am I in bad luck and received a second faulty kit or is there something wrong with motherboard ? Any idea how I can check this conclusively ? Any diagnostioc tools or something like that ?
Thank you for your help !!!
