Change the position of the console and controller: Sometimes, simply changing the positioning of the console and controller can improve wireless connectivity. Try moving the console closer to the controller or changing the direction and angle of the controller.

Hardware Malfunction: In rare cases, hardware issues with the controller can be the root cause. This may involve a faulty Bluetooth module or other internal components.

Inspect the USB Cable: Examine the USB cable for any signs of damage or fraying. A faulty cable can cause connection problems and lead to the light blue light issue. Try using a different USB cable or try using the controller wirelessly to see if the issue persists. If you’ve encountered a light blue light on your PS4 controller, don’t panic! This issue can be frustrating, but fortunately, there are some troubleshooting steps you can follow to resolve it. Let’s dive into the solutions below:

Low Battery: One of the most common reasons for the light bar turning light blue is a low battery. When the battery level drops significantly, the light bar changes color to indicate that it needs to be charged. What should I do if none of the troubleshooting steps fix the light blue light issue on my PS4 controller? If the controller doesn’t connect or the light blue light persists, try using a different USB cable or USB port on the console. It’s possible that the issue lies with the cable or port rather than the controller itself.You can use your wireless controller to play games streamed from your PS5™ console or PS4™ console to your compatible device using the PS Remote Play app. Connect one end of the USB cable to the charging port on the PS4 controller. Ensure that the cable is securely plugged in. If the light blue light on your PS4 controller is flashing due to a low battery level, replacing the batteries can certainly resolve the problem. Ensure that you are using compatible batteries, such as AA batteries, and follow the manufacturer’s instructions to replace them. If the issue persists after replacing the batteries, there may be other underlying causes that require further troubleshooting. Press the PlayStation button on the controller to turn it on. The light bar should now display a solid color, indicating that it has successfully synced with the console. Outdated Firmware: If the firmware on the PS4 controller is outdated, it can lead to various issues, including the light bar turning light blue. Updating the firmware can often resolve this problem.
