PS4 boot to logo then black screen diagnosis and FIX see description

In this video explain how to identify your problem so in my case my PlayStation booted up to the PlayStation logo then it went to a black screen and the tv screen kept detecting an input, the back light kept going on and off on my TV. So I assumed that the HDMI worked in the GPU did not fail But I checked the HDMI output on my PlayStation four to make sure there were no bent pins and I also tried changing HDMI cords on the TV. I made sure my PlayStation was directly powered into the wall because I know my PlayStation randomly shuts off when it is not directly connected to the wall. I went to the PlayStation website downloaded The latest full update+operating system for system initialization. The way you can tell is the update is usually under half a GB and the update+ operating system is usually over 1 GB. I followed the PlayStation website instructions and made a PS4 folder and in the PS4 folder I made an update folder and in the update folder I put the update and the operating system.

Next thing I did was boot my PlayStation into safe mode by holding down the power button for seven seconds until you hear the second beep. (Make sure your ps4 is all the way off) before you press it. This takes you to the safe mode menu then you click on initialize PlayStation four “full install”

I did this and nothing happened so the next step that I did was I took out my hard drive from my PlayStation 3 put it into my PlayStation four did the exact same steps for installing the update and operating system and bam my PlayStation works now! #PS4Repair
