Hi! SO my screen is completely black when it's turned on with a sliiiight hink of dark blue (that's why/how I know it's on). It just stopped working all of a sudden when I was watching a YouTube video. I could hear the audio but there was no video. I tried to do a reboot (watched a video about it on YouTube on my phone) buuut that didn't work. Thoughts? Tips? Much appreciated. Halp!
