Touch screen unrepsonsiveunresponsive but lcd seems to be fine

Texto:

Im repairing a cracked s4 screen. Removed logic board and everything else before removing the glass. All seemed to go ok and lcd boots up but not repsonding to touch at all.
 
I tried the glass free lcd in another s4 and its working fine so im wondering if its possibly a board problem?
 
Tried the board on another screen and no touch screen again.
 
Phone was in poer saving mode but ive hard reset it but still no touch. Is there any possible workarounds to testing the board etc to see if anything is damaged,iv eputdamaged,ive put it up againtstagainst the working board and cant see any difference.
