Black screen after trying to repair, how to fix?
Hi, I encountered a problem while repairing the display of a samsung a50.
I tried to get this display (with frame):

I mounted it well and everything worked perfectly except for a problem I encountered with the ear speaker, so I reopened everything to try to figure it out. In the meantime, however, when I turned the screen back on, it started giving me problems. First half of the display went white, then all white, and finally now nothing is showing. The touch works, but it does not display anything on the screen, all black.
I am afraid that the frame I purchased is not worth much, despite the fact that the reviews are positive. I can't find any other explanation at the moment, I don't see what accidental damage I could have done by simply reopening it. What advice can you give me to solve it? Thank you.
(The problem he was experiencing before trying to repair it was different, black screen and touch didn't work either)
Here you will find video showing the problem and pictures on how I assembled it:
