Console doesn't turn screen off after idle time

So as the title said, I have an RG35XX H, in which I did experienced the horizontal line issue and attempted a fix from another post on this forum, that was an easy fix. However later on I noticed that the screen did not turn off after the idle time, which was 10 second that I set in the settings, anybody have this issue and do you have a fix?

(Note: I’m using the latest version, Funky Jacaranda)

Another thing I observed: It seems that it kinda work, when I turned off WiFi that is, would still wanna hear what’s going on with this?
