iPhone 4 left side of touch dead

i have a ip4 mainboard i would like to get working again.

The touch on the left side is unresponsive on all the screens i connect, so it is a mainboard issue. i have heated to mainboard to 150 degrees on a preheater, cleaned the connector with spirit, restored. no luck.

Have anyone got a solution for this? i have a bunch of defective mainboards to take parts from.

Answer this question I have this problem too

This is way out of my league. But look very closely (high mag. if you can) at the digitizer connector on the logic board. See if any pins are corroded, damaged, missing. If the logic board connector for the digitizer flex is faulty, this would be a relatively easy fix.
