I run a cell phone repair company and we do quite a few repairs but this in particular HTC One X has us all stumped here. We do realize that there are 3 different versions of the dig/lcd and we have the correct part. But has anyone had problems with trying to replace the HTC One X dig/lcd assembly. It seems that after I put the new part on the lcd is black but the phone is still on. I even went back and put the old screen back on and it is still black. Prior to the repair the lcd worked fine. But just the digitizer was cracked. I have even went as far as changing the motherboard on the phone to a new one and am still having the same issue. Any help would be greatly appreciated!
