MacBook Pro Blank Screen (Built - in & External)
I restarted my MBP last night, and it proceeded to go through the shut down process and restart. The starting chime can be heard, but there was no image on the monitor, just black. I opened the lid to start troubleshooting the issue. Blank screen on the MBP as well. I held the power button down and forced another restart, to no effect. Still a blank screen. I disconnected everything from the MBP and tried again. Still a blank screen. I've reset the PRAM, and also the Power Management setting. Still not working.
From as best I can tell, the MBP is booting up with no problem, I just have a black screen, so the computer is currently unable to be used in any capacity. I let the computer start up, and run for several minutes. I then sent the keyboard command to log off, and I could hear the computer activity increase.
I have not installed anything recently, I did note that there was a firmware release yesterday, but I've yet to install it.
One thing to note is that the light on the latch is very bright when the lid is closed, but grows much dimmer when the lid is opened. Maybe I haven't noticed this before, but it struck me as unusual.
