If you’re having trouble seeing the yellow light on your PlayStation 4 controller, there may be a few things you can do to fix it. First, make sure that your PlayStation 4 is turned on and connected to the network. If it’s not, try turning it off and back on again. Second, make sure that your PS4 is in “safe mode.” This can be done by pressing the power button for about 10 seconds and then pressing the “reset” button. Finally, try changing the color of your PlayStation 4 controller’s light by going to “Settings” on your console and selecting “Controller Settings.”
