I replaced phone screen... But still not touching.


1 month ago, I did mistake about IPA-watering inside phone screen(In this time, this phone touch was still working). so I disassembled, dried, and tried again. But this problem started since that. touch screen was not working. even ghost touch! I ordered new screen parts, assembled, and hard reset, tried it again. But still not working. I think that screen parts have no problem, Instead of, all of problem is in mainboard. But, the phone can turn on. What’s that? What should I do?

Answer this question I have this problem too

Is this a good question?
