Help is apperciated

[deryq]

Hey everyone. My Galaxy s4 recently been acting strange like screen not turning on only capactive buttons light up. Notification led lights up and there is power on sound
Tried this method on YouTube :https://www.youtube.com/watch?v=O1p5mvu2fsc
and yay.. at least got the phone's screen turning on.
But... sadly it only flickers and turns right off. After I fully turn the phone on, I press the power on button once it flickers again and then the capacitive buttons light up. Once those turn off, I press it again, flicker again and it keeps repeating.
Help is apperciated.

I managed to capture the flickering moment by video taping it and pausing the video.
Here is also a video of something similar to my problem.

Welcome to the forums. The display most likely failed. Do you have any local repair shops that can replace it?

Thanks so much for the friendly welcome Yes I do have local repair shop but I read the comments, people suggest a loose cable.

That may be, but the ribbons and cables connecting everything can be quite fragile.
