Ask them for the Service Manual.
I have replaced Ipad screens before and iphone screens but when I opened up my Dell I was confused. I removed the front cover which I assume is a digitizer and saw this. The removal and replacement process is rather foreign to me most because there is a cord coming out with tape covering it. IT is not a cimple unplug process and plug in the new one. So if anyone can tell me about and provide links to the process I would appericate it because all I can find are Ipad screen replacement instructions. Also please let me know about any suppliers that might have this part because all I can find is the LCD screen. I have Googled this but I am stuck.
