12.3 inch QHD LED LCD Display Touch Screen Digitizer Glass Panel Assembly for Microsoft Surface Pro 4 1724

It sorted the cracked screen but now I have lost the touch screen ability. Would like to contact the seller to ask for advice but can't find a way to do that

Arrived quickly. Very well packaged. I replaced the screen myself and it works perfectly.Their service was also very good as I needed the flex cables in addition to the screen. They supplied those and shipped them quickly.

So i thought i could fix the broken screen myself, did everything i had to do and it was not working, worried i had done it wrong a pay a professional to look it over for me. she told me the connection were missing pins
