Whether you’re new to the PS4 or not, having a flashing blue light on it definitely warrant attention. Your PlayStation console can show a varied light indicators and having a blinking light on it can either be a signal of serious problem or a temporary bug. This problem started occurring with the first batches of the console years ago and so far, the problem has not gone away for good.
If you’re one of the unlucky PS4 owners who has this problem, this troubleshooting guide will help you identify the cause. Hopefully, you’ll be able to fix the problem on your end with the help of the solutions below.
Common causes of PS4 blinking or flashing blue light issue
Although the PS4 flashing blue light issue is no longer as widespread as it was years ago, there’s still a number of users experiencing it from time to time. This is due to the fact that the problem can be caused by a number of factors. Below are some of the common reasons that we’ve identified for this problem over the years.
Random PS4 bug.
Your PS4 may show a blinking blue light temporarily due to a random glitch in the system. This can happen when the console has been used continuously for an extended period. It’s also possible that the system may have frozen. Try rebooting it and see if the problem goes away on its own.
Non-functional PS4 Power Supply.
If your PS4 is not turning on and only shows a blinking blue light, there may be an issue with its power supply unit. Power surges can easily damage the power supply. Try disconnecting the PSU from the console and the wall outlet and let it rest for at least 10 seconds. If that won’t work, unplug it from the power strip and connect it directly to the wall outlet.
In some cases, a TV issue may prevent the console from booting up. Make sure that your TV’s firmware is fully updated. If you don’t know how to do this, consult its documentation or manual.
Bad HDMI cable.
A faulty HDMI may result to a host of easily detectable problems like poor or no video and audio or a flashing blue light on a PS4. If there’s a visible sign of damage to the cable like a bend or breakage in the insulator, replace it and check for the problem. Make sure that you turn off your TV and PS4 before unplugging both ends of the cable.
PS4 software glitch.
Sometimes, a random software bug can lead to light indicator problems on the PS4. If you’ve been using your console for offline play only, connect it to the internet and see if there’s an available software update.
Console hardware malfunction.
A more serious reason for flashing blue light issue is hardware problem with the PS4. If none of the solutions below helps, you can assume that your PS4 issue may be caused by a hardware fault.
Troubleshooting PS4 flashing blue light problem
Below are the steps that you can do to fix your PS4 flashing blue light issue.
- Reboot the console.
Your PS4 console may have not fully completed the boot process and gets stuck. Try turning it off on the controller first and see if it works. You can also try to reboot it by pressing and holding the Power button in front. If it doesn’t respond, unplug it from the wall outlet or power strip and wait for about 1 minute before turning it back on.
- Try running the PS4 on Safe Mode.
Follow the steps below to restart your PS4 to safe mode. You should do this if your PS4 is stuck but won’t boot up normally. These are the steps on how to boot to Safe Mode:
-Turn off your PS4 by pressing the Power button in front. It should blink a few times before the console powers down.
-Press and hold the Power button until you hear two beeps: one when you first press and another seven seconds later.
-Connect your DualShock 4 controller with the USB cable.
-Press the PS button on the center of the controller.
If your PS4 console boots to Safe Mode successfully using the steps above, this means that the cause of the problem is most likely software in nature. Make sure that you check for updates to fix any possible software issue.
You can also try to use the Initialize PS4 or Initialize PS4 (Reinstall System Software) options to fix possible software problems in this mode.
- Check the Power Supply.
If you can’t make the console enter safe mode, make sure that you check the Power Supply Unit or PSU. You can do that by pressing and holding the Power button in front of the console for at least 10 seconds. If the console beeps twice or shuts down let it do its thing. Then, disconnect the power cable from the wall outlet and the back of the console for about a minute.
- Use another HDMI cable.
As mentioned above, one of the causes for PS4 issues can be the HDMI cable. If you have another cable, try using that and see if it will fix the problem. Before unplugging, make sure that both TV and console are off.
- Check the PS4 and TV HDMI port.
A bent HDMI connector on either TV or PS4 console can similarly cause flashing blue light issue. Make sure that you do a visual check on the HDMI ports of the both devices. If there’s any damaged or bent PIN, you’ll probably end up repairing the device as there’s no remedy for that.
- Update TV firmware.
As TVs evolved over the years, keeping everything, especially the software side of things can mess up sometimes. Although manufacturers do their best to make their products as compatible and bug free as possible, coding errors or bugs can still happen. To lessen the chances of TV firmware issue, make sure that you check for a software update at this point.
- Verify PS4 hard drive is working.
Checking the hard drive on a PS4 is only advised for advanced users. It requires opening the console (and voiding the warranty in the process) and looking for obvious signs of hard drive damage. If you can’t do both, let a professional do it for you. Better still, send the console in for repair.
Repair: Get help from Sony Service Center or third party shop
If not one of the solutions in this guide help you fix the issue, there must be a more serious reason for your PS4 problem. At the minimum, you’re looking at repair option at this point so be sure to contact Sony for help. We recommend this even if your console is already out-of-warranty (but otherwise unopened by you or someone). If your PS4 was previously opened by you or by an independent technician, Sony will refuse to look at it. In this situation, try bringing the console to a third party repair shop.
