Answer to: My phone works but my screen is blankSame thing for me on my GT-N7100 After drop on the ground and with a new screen at the beginning i have sound right and left lights on low side. After search on the ned and reading the service manual i found shortcut on capacitors. I replace the two capacitors and now work perfect. I think that can work even for s3. See my photo with red circle on capacitors. Bye. Doriano.
