Welcome to the forum
It is weird that your laptop's screen is at full brightness when switched off.
This might not be only lcd but the systemboard might be at fault too since all of the parts are connected to it and it is the one who sends the signal to the lcd.
I suggest you ask the support to check the systemboard too.
You might try a bios update too.
Hope this helps
