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?
