iPhone 5s: Apple logo and then black screen - after screen replacement

Hello, I have an iPhone 5s that goes to a black/blank screen but first the Apple Logo comes up. I replaced the screen on it, I've done hundreds of screen replacements before without a problem. I'm always careful with electronics since they tend to be very fragile (anti-static wristband and no metal tools). I tried searching up the issue on several other forum with no luck, I figured I could give it a shot to see if anyone else has come across this. The iPhone doesn't go to DFU mode or recovery mode, it simply reboots back to Apple and then to black/blank screen. I tried forcing it to DFU mode with RecBoot as well without a luck. I'm assuming it's a board issue but wanted to know if anyone knew what I would need to replace. I'm comfortable doing SMD and good with a soldering gun. The display comes on fine, it's not faded or lacking brightness so I doubt that it's the LCD capacitor but I really don't know. Hopefully someone can help with this very weird problem. Thank you for your time!

-If anyone has a link for a application like recboot that works, that would be appreciate as well, Thanks again!

You seem to know your way around the phone. I hate to suggest it but have you tried to use a different screen to see if it's just a bad part? I've had a few of those lately (mainly on the 6 and the 6 Plus) that seem like they are working, but they either force the phone to constantly restart or they do what yours is doing, and they just bootloop. It's rare but if you bought the screen already prepped, it could be the front camera causing the restart if it's a bad part. Worst case scenario you can try the broken screen on it to see if that still works, assuming the LCD didn't blow on it.

Wish I could be more helpful, but they best of luck anyway!

I've tried several other screens, original and after market. All it does is hangs on Apple logo as if it was booting but then suddenly turns completely black. No sound or vibration upon switching vibrate switch on and off. It's very odd. I'm sure it's something to do with the board but wanted to see if anyone knows what component to switch out since I have spare bad boards to take components out from.

This usually happens with a faulty battery or battery connection. The phone has enough juice to power the display but as soon as the other components start to online the phone crashes and attempts to start again. Try a new battery and verify the connection from the battery to the motherboard.
