Touch on the LCD not responding

I have a P8 Lite that endured slight liquid damage about a month ago and after removing the Logic Board out making sure that there was no corrosion or liquids on the inside i put the device back together and as well have tested 3 other LCD's on the same logic board and they all have the same issue. Is there an IC i can replace or Reheat to get the touch to respond again?

Did it work before opening it?

It worked after the Liquid damage for about a month then suddenly stopped working.

Is there anything important on it, if not then have you tried a Factory Reset?

did you find any solution?

It seems to be the touch ID IC that needs to be replaced. I cannot get spares or have 1 to try that theory out but it would make sense to replace that or the connector that the touch uses because of corrosion it could still be shorting under the connector.
