So awhile back I had my phone(920) knocked out of my hands on a bus and the screen cracked. Okay no big deal Ive fixed electonics before so I bought and replaced my phone screen with this D/Touch Screen Display Glass Replacement f?r Nokia Lumia n920 920+Tools | eBay[1] After replacing the screen it worked okay, not as accurate or responsive as before though and with a little dust that I had not noticed putting the screen on. A few months later I have some free time and decide to get rid of the dust and maybe ill notice why the lights under the windows and search button are not working so I took it apart again however on putting it back together the touch screen no longer works. The screen seems fine, the picture looks perfect and all the on/off volume buttons work. I did some looking and thought perhaps the digitizer was broken however I tried briefly putting my old now broken, dusty screen back on as the touch on that also worked before. However the oldscreen also didnt work so now I am not as certian a new screen/digitzer combo would fix my problem. I am not sure now what could be wrong I THINK I put everything back correctly after totally taking it apart a few times. Anyone have any ideas of what could be wrong? Or if there is another fourm I should post on that could help me? I can post pictures of everything if needed. Thank you!
