screen blank unless at certain angles
this seems similar to the issue of most of the Mac notebooks where the screen is blank at certain angles except this is happening with a Dell XPS13 that's been faithful for the last 2-3 years. a few days ago the screen started to flicker before turning off and despite a reboot the screen didn't come back on. it wasn't until the screen was adjusted that it was determined it works at certain angles and immediately goes black at other angles. any suggestions on what to do for this?
