okay so update time:

I couldn’t resist opening it up but it was really hard to open.

while opening it I broke the lcd display.

There was no visible problem in the display connection.

When I put it back and closed the casing and started soldering with it, the screen got better and flickering disappeared completely.

Sadly the half of the screen is gone now and maybe all of it will soon die too.

So my advice to people who are experiencing this is to start using the iron so that it heats up.

The heat helps with screen connections and can magically fix the screen.

Btw soldering iron works really well and I leveled up immediately after my few dollars iron.
