I've just changed the touch screen (second time in two months) from my white Xperia M. First time everything was perfect, but his time I've also changed the LCD display, as the original one was cracked. Now, the display works ok (it lights and no damaged pixels, etc...) but the touch doesn't respond. The touch screen I've assembled is black, is that the problem? No compatibility? (Strange)
All connections are ok and clean (I've used the Troubleshooting guide - Mechanical), I've done a software update, a hard reset...but nothing.
Any idea? Maybe the new display or the new touch are faulty?
I haven't found any messages with these issues, thta's why I'm writing a new one.
Thank you.
