How to fix my iPhone 5s screen? - 1

I replaced my iPhone 5s screen by myself and I have done this before but this time when I turned on the screen it was blurry, fuzzy and faded. Can I fix it on my own? I don't know what I did wrong this time, I did the exact same thing as I did last time.

Make 100% sure that the LCD cable (I don't know which one it is) is completely plugged into the logic board.

If you're 100% sure that it's securely in place, then it's possible that the display you bought is defective and you might need to return it.

The most common mistake on those is that when the ribbon connectors to the screen are fitted, the screen is allowed to go past a 90° angle relative to the phone (sonthe phone lYs flat on the workbench and the screen goes past being vertical whilst still connected). That almost always damages the ribbon connector by fracturing one or more conductor tracks on it. If so then the fix is another new screen.
