Hello everyone, I don't know what it is, but I accidentally turn on my TV and LibreELEC 9.2 for Raspberry Pi 4 has a spilled screen, as in the attached picture.
The TV itself and the screen spilled.

I've never seen such an error in this forum. Is it a reproducible error? If yes, describe all steps you did.

Adjust the horizontal hold and turn the screen right-side up

I don't know how to manually reproduce this problem. I don't know what causes it. when I get up in the morning and come into a dark room, it's pretty scary.
I try to make gif from LivePhoto, in attachment.

By the looks of it, you are using the TV upside down...
Do you get this screen when you turn the TV first on and then the RPi ? Or vice versa?
If it happens every time, try a different HDMI cable.

My theory: You had a power outage, which turned on your TV by a CEC signal that came from the RPi. The power outage was leading to a bad HDMI handshake, resulting in a wrong HDMI mode.
Things you could do to avoid such situation:
- don't use your RPi in always-on mode, and install a power button instead
- edit your RPi's CEC adapter settings to disable the CEC wake up of the TV
PS: It's like in that "Poltergeist" movie.

I apologize for the first attachment, I took it on the iPhone and it will not be compatible with the orientation. I don't have the TV upside down. This morning the TV did not turn on myself this time, but after the manual switch-on the picture was broken. I tried to change the resolution to 1024x768p, the broken picture disappeared! but when I switch back to FullHD it's broken up again. I am sending a picture of HDMI CEC settings.

If the cable cannot handle FullHD signals try a different one.
If the TV cannot handle FullHD signal, try a different HDMI port on the TV (if possible).
Is there a setting on your TV to handle specific TV settings?
My 2012 LG TV has something to that effect.
