In general, the pulsing blue light indicates the PS4 has no audio or video output. The problem may revolve around TV compatibility, the PS4’s power supply, the power cord, corrupted software, corrupted hardware or other hardware issues.

PS4 Blue Light of Death causes?
It prevents the console from responding or sending signals to the TV. That means it won’t even enter Safe Mode by conventional matters, enter any menus, or play any games.

Their troubleshooting is as follows:Let’s expand this short troubleshooting and add more options.
Power Cycle the Console
Fixing the Blue Light of Death often requires entering safe mode. However, you won’t be able to enter the recuperation menu as easily. Instead, you have to power cycle the console. It’s the step everyone should try as it erases random bugs and helps users enter Safe Mode.
Reset the Resolution
Resetting the resolution is a common solution user share on forums. However, it requires some tricks regarding your HDMI cable. Here are the steps: Now, you should test the PlayStation 4 by shutting it down and then on again to see if it works. Bear in mind this option doesn’t require an internet connection.
Factory Reset the Console Offline
The solution above may have three results. The first one is that it worked, so you don’t need to read further. But if you never saw a white light and didn’t use Safe Mode or you Initialized the PS4, but then it shut off by itself or showed the Blue Light of Death the next time you turned it on, try re-installing its system software with a USB drive. The USB must have at least 6GB of free space. This process erases your data. You would only want to do it as a last resort. Here are the steps to re-install the system software:
Open a web browser on your PCGo to PlayStation’s official page.Scroll down and download the “PS4 Console Reinstallation File.” It downloads a file named “PS4UPDATE.PUP”Plug a USB drive on your PCRight-click the USB drive and press “Format“Click “exFAT,” “exFAT,” or “MS-DOS(FAT). Press Start to format the drive.Create a folder on the USB drive, and name it “PS4“Create a subfolder within PS4, and name it “UPDATE.” The folder names must be exact and without the quotation marks so the console can identify the filesPlace “PS4UPDATE.PUP” inside the UPDATE folder
Now, on to the next step, which is re-installing the software: Either way, after the re-installation finishes, the console will start normally. See if this fixes the problem by re-starting the console.
Upgrade the TV’s Firmware
Another option, Sony recommends updating the firmware for your SmartTV. Generally, these are the steps you should follow:
Press the Home or Menu button on your TV controllerGo to the TV’s Options, Settings, or Configurations menu.Search for Software Update. It is commonly within a Technical Support sub-menuUpdate the firmware
There are many Smart TV brands, as well as various operating systems. Check your TVs manual, or check online to find specific instructions.
Remove the Hard Drive
Another Sony recommendation is checking the HDD bay. You can slide the HDD cover in the arrow’s direction to remove it. Then, ensure it’s properly sealed and that the hard drive is properly secured and connected.In particular, here are some tips:
The hard-drive position is different on the PS4, the PS4 Slim, and the PS4 Pro. However, there’s always an arrow indicating where it is.Use a T10 screwdriver to open the drive-bay ports. Unscrew the bolts to slide the cage. You can replace the hard drive with a new one. A faulty hard-drive may cause slow gaming performance, clicking noises, and corrupted files. You may have experienced these issues before the PS4 Blue Light of Death.
Change the Cables
The next step is checking the AC power cord, HDMI cable, and HDMI ports for physical damage.First, you can clean the dust and rust from the port with canned air and a microfiber cloth.You can try using new cables and see if it solves the issue. This is particularly important if you see signs of damage in your cables.
Take the Console to Service
The PS4 Blue Light of Death could be the symptom of a dead CMOS battery, among other hardware issues.In particular, the CMOS battery is a small piece that stores date data. Moreover, it feeds the CMOS cheap so the console can store hardware settings.Now, changing the battery requires some hardware knowledge, so we don’t recommend you to open the console to remove it or change it.Moreover, there could be other hardware damage within the PS4. That includes dust, rust, faulty cables, faulty boards, and similar. For example, overheating could be a problem. A professional may need to work on the console’s cooling systems to fix the issue.So, if the solutions above don’t work, sadly, you’d have to take the console to a repair store. Either way, read the follow-up solution to change the CMOS battery yourself.
Change the CMOS battery
Removing and replacing the battery forces a reset of the CMOS chip, which causes a firmware reset. Therefore, it can breathe new life into a seemingly dead PS4. Here are the steps:
