[BUG] The Touryst - black screen, won’t load after pressing “A” to start

I've had the exact same problem. No real problems since day one, but then this black screen on Dying light started. After that I started NBA 2K15 and had no save data. The same with GTA V. Then I tried Far Cry 4 and it said press A to start. Then it says
loading data and says press A again.

Black screen is a bug that will be addressed soon.. In the meantime, a "Soft Reset" addresses this... Press and hold consoles power button for 8-10 seconds until it powers off. Wait 30 seconds, then press power button again to boot. It will take a bit longer
to boot and stay on the green screen for a bit until it loads completely. This will address that black screen and more.

If this occurs again, this is your first line of defense. Hopefully a patch will be out soon.

Does this work if it loads to a black screen only. On March 2nd I cold rebooted my console, due to lag on the tv side. When I turned it on the screen stays black. Light on console comes on and make the sound when power button is pressed. After that just
a black screen.

As far as the black screens, there was a bug introduced in the last update. The fix for this is a soft reset. Press and hold power button for 5-10 seconds. Wait 30 seconds, then press again to turn on. There will be a bit longer loading time while the system
loads. Please be aware this is a temporary fix for a situation that may or may not occur again. This is a known issue that will hopefully be patched soon.

Perform a "soft reset" guys. This will address the black screen bug. Press and hold consoles power button for 8-10 seconds until it powers off. Wait 30 seconds, then press again to reboot. The green loading screen will stay up for a bit until the system
boots completely. Hopefully a patch is on the shortlist to fix this. If this happens again, this is your first line of defense.
