My screen fell and became black, what should I do?

I have Samsung galaxy tab a 10.1 (2019)
The screen glue that kept screen with it was weakened somehow and screen was coming out multiple times but since it was not a big deal as everything seems to work perfectly I ignored it.. Until today My screen came out and fell on my table ( u can assume position of tab like distance to be like 20cm touched with the surface with angle of 80° approx.)

I don't know how much damage it did internally but what I can observe was the ribbon/ flex cable or whatever you call that cable came out of screen

I panicked and tried to put that back and black screen of pixels which glow a bit white on ends showed indicating that the screen was working

I repeated the same process by unplugging and re-plugging the cable again and again then suddenly I noticed drastic heat or overheating in cord and when connected to screen, In screen as well, I was panicked again and removed it again and repeated same process after sometime...

Note that there is no physical sign of broken ribbon or screen

and now I can see nothing is working either plugged or unplugged But i can hear sound by checking by my Bluetooth speaker indicating that its on

Also Bcz of some reason I cannot go to a repair shop or buy some new replacement for it

Can you please help me in fixing it myself at home???
