Hi, mate I'm just wondering what the problem with my laptop Acer Nitro 5 is when I turn it on its almost the entire screen is black but after a while probably 40-50mins time the screen is working fine with flickering on the top portion of the screen and after 10-15 mins the flickering is gone. I also try connecting it to external monitor and it's working fine, Thank you in advance for your answer. Cheers
