Ever since a few days ago my screen has been going blank. I don't understand why this is happening. I even cleared the Pram to no avail. When I say it goes blank I mean that it goes to brightness level 0 so you can still faintly see the screen if you look hard enough. To get the screen to return I must turn the brightness down to 0 and then turn it back on. This literally makes no sense to me and probably to you. This has never happened before and I cannot comprehend why the screen will go blank when the brightness isn't set at 0. And sometimes after turning the brightness back up it will immediately go blank. If I move the tilt of the screen, the screen will go blank. I don't understand why this is happening and any help you guys could provide, I would be very grateful!
