TV unexpectedly turning off?

Hi!

I have a 2020 The Frame (TV Samsung The Frame QE43LS03T QLED 4K UHD Smart TV 43''), and I've started to run into an issue that I'm kinda afraid is announcing doomsday for my TV.

It happens 99% of the time with the Netflix app directly installed on the TV, and it can happen after 20 minutes, or 2 hours, or not at all: the TV just turns off.

It turns back on immediately and seems to be running fine, but I'm afraid it's a sign of overheating and the TV is protecting itself.

TV's on the wall, 'control box' is inside a drawer of the Ikea furniture that is under it. Whether the drawer is open or not does not seem to change this behaviour.

Using Netflix on my ISP TV box does not trigger this effect.

If anyone has any insight as to what's happening, I'm all ears.

Thank you all so much in advance.
