POCO X3 Pro problem

[SirM3]

Hi!
I have a POCO that was working fine with MIUI 14 stable v14.0.3.0.TJUMIXM_v14-13 until I had a problem with the screen.

When I start the phone, the "POCO" logo is displayed then the screen remains displayed on a lit black background. When I press the Power button, I can see that the screen turns off and that if I turn it back on, it's the lit black background that appears as if the system was loaded but nothing seems to display.

The only thing I tried was reinstalling the ROM by doing an update without format with Fastboot but still the same problem.
I can boot TWRP or Fastboot.
I hope that someone could help me.

Edit:
Problem resolved

Hi, how did you fix it? In my case I have noticed, that the phone works in the background, but the screen stays black until it's unlocked (I was using a pattern lock, so I had to blindly try to draw it on a black screen). When it's unlocked the screen starts to work normally. So atm I have no screen lock protection and also I am having problems playing videos on youtube, using camera video recording etc.
