If your Touchscreen/Home buttons are not working (Probable Error)
About two months ago, my screen decided to die. I ended up getting a new phone, but I still had my Play sitting here bothering me. So I decided to get to fixing it.
When I tore it apart, I thought that the digitizer had died, but what I found was actually the connecting the digitiser, LCD and Buttons together was damaged.
So I ordered one on ebay for about $10. When I got the cable, it seemed to be about 3-4CM shorter than the OEM one. Which supports why I think this may have been a design error on Sony's part. What was happening was Sony's god awful mechanism for sliding the screen up and down had pinched the cable, and caused it to be damaged.
I know this might be a longshot, but I think that some people might be able to save a dead device by replacing this one simple part, I know it worked wonders for my play, as well as a friends.
I will post a link to the part as soon as my post count is up.
