If you remove white digitizer ic you have to measure pins that goes to cpu!

sTEP 1 - check values of all pads (diode mode)
step 2 - check all voltages and power supply
step 3- USE Original TOUCH IC from other phone
step 4 - user Original Lcd to test

My experience with square lines after replace as in your case both 2 ics, is with u2401.
- i've remove u2401 than power on the phone and if square lines don't appare i know that this is the problem..
so at the time i did new reball or replace with correct ic (u2401) alignment and solve.

the chassis is ok , is crooked or deformed? because if the sockets where the m.board is laid are not perfectly aligned the problem will reoccur as long as they have been welded well.
