iPhone 5S backlight broken after screen replacement?

So back in December I cracked the screen to my iPhone 5S that I had only had for around 2 months. I was not a happy camper. So after a month, I was able to buy a replacement screen with the intention of repairing the screen myself. So I received the screen and replaced it as instructed in a video on youtube. Everything was going fine till I closed up the phone after the replacement. The screen lit up, but the home button wasn't right. So I opened up the phone again and re watched the video and found what I did wrong, and I fixed it and once again closed up my phone. Then I realized that something was wrong with the glass. The metal frame around it was not glued on well resulting in some parts of the glass being raised up from it. So I thought I could open it up again and fix that. So I did, attempted to fix it, closed it back up and turned it on again. But once I turned it on it was barely visible. I could barely make out the apple logo on the screen. Somehow during everything I must have messed up the backlight port inside the phone. As when I put back my older cracked one, I get the same effect. It's safe to say that I am absolutely furious at myself for this. I can't take it to Apple to repair, cause it's voided the warranty, and no repair place fixes the 5S's yet, let alone the problem that I'm having. So my question is: Has anyone else had this problem happen to them? Have you fixed it? How? Because of this I have no phone to use what so ever.
