Hello,
I am new in Raspberry PI but i would like to lunch LibreELEC on my Pi4 2GB.
I have a problem, because after i flash system and put sd in to Pi i get Bootloading screen, but few second later i get info on tv screen "please check power supply on your device"
Maybe someone has similar problem ? I tried basic fixing metode like adding comands like:
hdmi_force_hotplug=1,
hdmi_safe=1,
config_hdmi_boost=9,
Unfortunately nothing works for me 
I tried other OS but i have same problme.
I have Samsung TV AU8002 50'
Rasberry Pi4 2Gb
Original Raspberry PI HDMI cable and power supply.
