A few months ago, I broke the screen on my nexus 7. Recently, I decided to replace the screen. I bought a screen and put it in uneventfully, but I noticed that there was a diagonal stripe on the screen that didn't respond to touch. I knew that nexus 7s have touchscreen issues, so I downloaded the app Nexus 7 II Tester. One of the patterns caused the touchscreen to not return to normal after closing the app, so I restarted the tablet to try to fix it. However, after turning off, the screen would not come back on. The backlight is off. According to getevent from within adb, some touch input is getting through, but when I look at the screen through Android Screen Monitor, the touch input seems to be erratic. Aside from issues with the screen and touchscreen, the device seems to function normally.
