from several days, my brother was playing on an all-in-one PC (Acer Aspire z3-615) and the charger fell to the ground. He continued playing normally after that, but the next day, when I tried to turn it on, it gave me a black screen where the Acer logo showed first, then proceeded to a black screen, and when I hit the screen with a flashlight, I could see everything behind it.

-Things that I tried after I connected my PC to the TV via HDMI cable (where the display is fine) and it showed me the screen for a second before going black again:

1- pressing win key + shift+ + ctrl + B

2-alt + tab when getting out of a game or other programs to the desktop

-Things I have tried but didn't fix the black screen:

1. Unplugging and plugging all cables and charger

2. entering safe mode ( as my TV can't show anything until I reach the login page)

3. uninstalling (Intel had graphics 4600) from the display adapter in the device manager and installing it again

4-updating Nvidia GeForce 840m

P.S: I just want to make sure if there is anything I can do to fix the black screen by myself with your help or if it is necessary to go to a technician.
