Hat geantwortet auf: Why is the bottom of my touchscreen unresponsive?I may have two possibilities for you: the first is the flex cable was damaged when you replacing a new lcd, you can try to assemble it again until you get a light clicking sound. the second is you replaced with a bad lcd. maybe you need to try another lcd, but be careful the first possibility.
