Changed LCD/Dig and now no touch
I changed a damaged iPad Pro 12.9 digitizer/lcd - the touch on the damaged one still worked when i took it off. I solder the daughter board to 2 different new display assemblies and neither one have touch that works. The picture displays perfectly fine but i am unable to swipe.
any ideas would be greatly appreciated

I have this problem also. Waiting on a replacement screen to see if it is the screen or not. When i first soldered the new screen and connected it, it worked. And then when i put everything back together, it stopped working.
I'm sure you both figured out that you had the battery connected when you reattached the screen - causing a short. You have to get it microsoldered to get it fixed.
I have he same issue, after my 3rd screen replacement. Finally got a good screen the 3rd time around and touch worked for about 2 weeks before it just stoped.
