I am trying to repair an iPhone 5S. I have tested its LCD, and it is working perfectly. I connected the phone to a laptop, and iTunes just responds correctly as if it is a normal iPhone, displaying its information, contents in memory, etc. But there is nothing on the iPhone screen. I wonder if there is anything other than the logic board that can cause zero video output to the LCD.
Is this a good question?

Press and hold down the Sleep/Wake button and the Home button simultaneously for at least 10 seconds. The screen will clear out and then the Apple Logo will appear on the black background. When the logo appears it means that the reset is done.

Do you have the old screen to test the phone with? If so try that and if that displays correctly then it's the screen it self

Try to reseat the connector if everything works
And do a hard reset.. Holding power button and home button
I have four different working screens to test with and none is showing anything. I also tried using a working logic board from another phone, and nothing shows up on the screen either.
Just done a full re-assembly and problem solved. still not sure about what went wrong though.
My sons iPhone 5s droned totally of power and even after being plugged in all day trying different iPhone chargers! It gives us the apple then goes to a black blank screen like it is on but nothing on the screen! I have tried several times to hold down home button and power button and it does it all over again with same results! Any help appreciated!

Can you see any sort of liquid damage on the logic board? A minor liquid can damage the conductors and transmitters.
