What's at the screen at the end, nothing is visible.
Two suggestions from me.
One, obviously try contacting the company.
Two, there should be a reset option in that recovery menu, try resetting your TV and if it's in Chinese language or something like that then use Google lens to live translate the screen.
hold the power button (behind your TV) for 10 seconds
Did you tried turning it off
Wtf is up with your wall.
Edit nvm, I googled samwon and found out it's based in the Philippines so probably explained the walls.
Dude, I stead of buying that TV you should have spend it on cleaning bottles, bleach. The look of that wall will certainly give you cancer at some point. That humidity level makes it turn like that.
Clean it well, removing most of the black stuff then paint over it using a paint humidity sealer. It's not a solution but a temporary fix unless you can see the cause of that humidity. Worry about your TV later
I can't see what's on the screen. Can you take a screenshot of that menu?
Imagine watching dahmer in there
RTFM?
And then?
Please heeelp
Samwon help
