Display turning off itself

My system fell in water, I took it to a local shop for repair and it was working back but the screen goes off even while working on it. It will only comes up whenever I press any key on the keyboad. This normally happens after the system stay up for like between 15-20 minutes after booting. Please what can I do

Since this has a history of liquid damage, it's likely that either a component on the logic board related to display logic is damaged, or a component on the display itself is damaged. I would recommend taking it back to the repair shop to see what they recommend! Otherwise you would need to open it up and inspect components for damage and possibly do some level of board repair. Good luck!

Liquid damage often effects the battery, have you checked the battery? Install this gem of an App CoconutBattery it will offer you a better view on what’s happening. Post a snapshot of the Apps main window here so we can see things as well.

I would also run the onboard diagnostics restart the system and press the startup D key to enter, did you get any errors?
