Your PS4 controller may be blinking white and not connecting to the PS4. In such a case, the problem is most likely due to a faulty IC chip on the motherboard. Another common reason for this issue is a power surge. Fortunately, you can fix this issue without having to reinstall the controller.
IC chip burns out on the motherboard
If an IC chip is burning out on your motherboard, it’s important to find the source of the problem. While the motherboard may appear to be working properly, the power supply may not be providing enough power. You may notice that the CPU fan is running, and the computer’s lights might be flashing. However, that doesn’t mean that the power supply is providing enough power for the computer. A CMOS battery is located inside the motherboard. If it is fried or not functioning properly, you can replace it with a new one.
To test whether an IC chip is burning out on the motherboard, you can buy a universal burn-in Motherboard. It has a chip installation area on it, and can be connected to the back side of the aging chip to be tested. You can also buy a chip tester that has a aging daughter board, which replaces the whole burn-in Motherboard.
Power surge can cause the issue
If you’ve ever had the PS4 controller blink white or fail to connect, this problem may be caused by a power surge or a motherboard error. Another common cause is buggy controller drivers. Because the controllers do not require firmware updates, they tend to be prone to bugs and can cause these issues.
To try and fix the problem, disconnect the power cord and reconnect it. If the problem persists, you can try switching to a different power cord. If that does not work, try re-plugging the PS4 and rebooting it.
Uninstalling the controller
If the PlayStation 4 controller keeps blinking white, there may be a problem with its connection. This issue can be fixed by updating the controller driver files on your PC. Sometimes the driver files for a PS4 controller get damaged or outdated, causing your system to malfunction. To fix the problem, you can update the controller drivers like any other device driver on your computer.
You can also fix this problem by using a second controller. To do this, borrow a second controller from a friend and connect it to your console. Then, use your second controller to go to Settings > Devices > Bluetooth Devices. Once your second controller has been detected, you should see a green light.
Repairing the controller
If your PS4 controller is blinking white, the problem is most likely related to the controller’s Bluetooth module. It may be faulty or the drivers have become outdated. To fix this problem, you can either replace the controller, or try using another one. If it doesn’t work, you can also contact an expert to repair the controller.
First, open the controller case and check the ribbon cable. It should line up with the circuit board on the upper side of the case. If the cable is damaged, it will need to be replaced. Also, make sure the USB port is connected securely to the PS4 console.
