How to fix blinking blue light on PS4: What a pulsing blue line means on PlayStation 4

If your PS4 has a pulsing blue light, there are a few fixes you can try to get the PlayStation 4 back up and running.

The infamous ‘Blue line of death’ is how your PS4 tells you there is a problem. It’s a pulsing blue line that warns your PS4 might no longer be operational.

Normal consoles pulse blue then turn white. If the PS4 continues to pulse blue and then powers off, then it indicates that the console did not send a signal to the TV, which bricks the device and stops normal operation.

Sony believed the problem was an isolated incident and released a troubleshooting guide highlighting options of potential fixes.

While the problem was prevalent at launch, it still happens for a small portion of users and is more likely to be an issue if your console was manufactured around late-2013. This is what you need to do…

Update your TV’s software

Sometimes the issue can be on the TV side. If you have a newer television, especially with internet connectivity, it’s likely that this can be updated and sometimes fixes the issue.

Check the HDMI

Try changing the HDMI cable to see if that’s stopping the TV from getting a signal. 

Check the power supply

Press the power button on the PS4 for seven seconds, until the system beeps twice and powers off. Afterward, disconnect the power cord from the socket and check the AC IN connector and power cord for any conspicuous damage.

Check the hard drive

Make sure your PS4 is turned off, then disconnect the power cord and any other connected cables before sliding the HDD cover outward. Once removed, inspect the hard drive for any potential damage and ensure it is properly inserted in the HDD bay.


Reset the Controller

Press and hold the PS button on your controller until the system light turns orange. Then, press and hold the PS button again until the light turns white. In some situations, this can get the PS4 to boot correctly.

If none of these solutions remedy the situation, then you might need to contact Sony!
