Hello, generally, the LCD connector pins burn on the FFC (flexible flat cable) that is for the backlight. Secondly, check the display and then check the PCB (motherboard). usually, LCD connector pins burns on FFC (flexible flat cable) that for the backlight.

Hello, thanks for the video. I actually wanted to know what is roughly at the top right behind the blinking light, because that's where my Redmi always starts to get hot, and by hot I mean 40°C and up. So I'll keep consulting Google/YouTube before I reset it to factory settings...
