Though the LCD isn't broken on your device, it looks like it is defective, if you have experience taking the S3 apart, and access to an additional S3, you could simply switch motherboards to test it. Honestly, it would be best for you if it is the screen, because the only other possibility is that your main logic board is having issues, which isn't good at all, in that case you would have to get a new phone all together.
