So a while back I was charging my S8, I came back to it and it had died. The phone itself does not turn on, when I attempt to power it onoit occasionally flashes a singular horizontal line (usually near the top of the screen). The phone does take a charge because those lines don't show up when the phone is dead. I have tried all of the methods to try and fix a black screen of death (i.e., hold down the power button and volume down for 10 seconds/30 seconds, with and without the charger, I've tried holding down the bixby button alongside with vol down and the power button). Nothing is working, I haven't taken it into a shop yet because I've been quite short on money. Any help would be appreciated.
