Samsung galaxy S3 Touchscreen not working?

[Ethan Kyne]

Two years ago or so, I dropped my S3 on a sliding glass door railing and broke the LCD beneath the actual glass display on the top. The display itself wasn't cracked, you could only see the crack beneath the glass on the LCD itself. The phone would not turn on and only the lights would appear, (vibration, sound, and LED lights all worked).

So after such a long wait, I attempted to repair the phone myself after much researching and observing from repair videos. I purchased a LCD Display + Touch Screen Digitizer Window unit that was compatible with my MetroPCS model, SCH-R530M.

I have successfully replaced the LCD and reattached the cables myself, following techguyz708's guide on YouTube: Samsung s3 screen replacement Tutorial LCD and Digitizer. I had no cracking of the new unit which I ordered, no cracks or scratches. Connected everything together and the screen turns on perfectly, no discoloration. It boots to my previous pattern-lock screen; but unfortunately my touchscreen is unresponsive and doesn't work so I cannot get through. I have read that resetting the phone to factory settings may work, but have heard many unsuccessful reports. (I would prefer not to have to hard-reset my phone because I have many cherished photos that I would like to recover somehow but have no idea if I properly backed up my files.)


Any suggestions or ideas?

It's probably a faulty screen. Where did you buy the LCD from? Or you could have not properly seated the cable that connects to the motherboard.

I think you are correct about the screen. The seller has agreed to refund my product and I will be shipping it back to replace it with a new one. The screen itself and image display were superb, but the touchscreen would not respond. I have tested the cable connecting between the motherboard and cannot further troubleshoot it, so I believe it is on the defective side. Thanks!

No problem, hope that you get it working. If the next screen doesn't work then there is an issue with your motherboard. Please let us know if the new one resolves the issue.
