If your PlayStation 4 is experiencing a blue light that turns on and off, this issue is likely caused by a hardware or software problem. Users have named this problem the “PS4 Blue Light of Death.” If your PS4 has this problem, there are several things to check first. These include your HDMI cable, CMOS battery, and power supply. In some cases, the problem can be solved by replacing the affected components.
Possible causes of a pulsing blue light on a PlayStation 4
A pulsing blue light on a PS4 is an error that may be caused by a variety of problems. One of the most common is a corrupted software file in the console’s firmware. You can try reinstalling the firmware, but remember that it will erase all your saved games and settings. Another cause is a damaged HDMI cable.
A pulsing blue light on a PS4 can also indicate a power shortage. If you’ve recently had a power surge, your PS4’s power supply unit could be to blame. Unplugging the console and reconnecting it should fix the problem. Alternatively, the issue may be with the television. In this case, you must update the firmware on your television.
Fixing a faulty HDMI cable
If the PlayStation 4’s HDMI port is showing a blue light, then there’s a chance that the cable is faulty. If so, you should replace the cable or try using a different cable. Another option is to remove the PlayStation’s HDMI port and check the connection. Sometimes, this can resolve the problem.
If the light is blue but still not displaying any video, it may be the HDMI cable itself. Try unplugging the cable from the PS4 while the device is off. The problem may occur if the cable connector is damaged or bent. If this is the case, the console will need to be fixed.
Fixing a faulty CMOS battery
One of the first things to try to resolve a PS4 blue light problem is to replace the faulty CMOS battery. This will reset the CMOS chip and firmware. To replace this battery, you’ll need a flat-headed screwdriver. Push the pin holding the battery out and then lift it out of the socket. Replace the battery with a new one and wait ten minutes for it to charge.
You can also try changing the AC power cord or the HDMI cable. If these are the causes, you can try cleaning them with canned air or using a microfiber cloth. If these methods are unsuccessful, you can try replacing the cables with new ones. A weak CMOS battery is one of the most common causes of a PS4 blue light. This battery stores hardware settings such as the date and time and lets your PS4 know when to shut down. A failing CMOS battery can result in data loss and a malfunctioning PS4.
Fixing a faulty power supply
If you’ve discovered that your PS4’s blue light is on and off a lot, you may be suffering from a faulty power supply. A faulty power supply will prevent power from reaching the motherboard. As a result, you’re likely to encounter a range of problems with your system. Fortunately, this problem is not too difficult to solve. The first step is to check your power cord for any cuts or cracks. If necessary, clean it with a microfiber cloth and replace it. Then, plug your PS4 back into its power outlet. If the power cord is faulty, you may also need to install a surge protector. This device diverts excess voltage to a grounding wire. However, if your surge protector isn’t working, it may not be much help.
In addition to replacing the power supply, you can also check the power cord to make sure that it isn’t tangled or broken. If that doesn’t help, you can also try using a different HDMI cable. Another solution is to perform a factory reset, which will erase all the data in your PlayStation 4. Before performing this step, make sure to back up any data that you’ve saved on your console.
