Why is PS4 blinking Blue?

Your PS4 is showing you a blinking Blue light because the gaming console was unable to execute a signal to the TV it is connected to. If your television cannot receive a signal from the PS4, there will be no audio, and visuals displayed on the screen. Instead of your console displaying a white light when it has connected successfully, the PS4 pulsing Blue light will indicate there was an interference. 

There are a few reasons why your PS4 is displaying the Blue light of death when you initially turn the console on;

Reason 1. PS4 network connection

Your PS4 will not be able to send a signal through to your TV if it is not connected to an internet connection that is not stable enough for your console to use bandwidth.

If your internet connection is on, but the connection is intermittent or too weak, this may be the reason why your PS4 is encountering the pulsing Blue light instead of the connected White light.

Reason 2. PS4 power supply

The power supply unit your PlayStation 4 is connected to could be interfering with the console receiving enough power to start up and connect to your TV.

This PS4 error is caused by a power surge, or if your console is connected to a faulty or damaged power unit.

Reason 3. Incompatible TV

Are you sure your TV is compatible with your PS4 console?

An incompatible TV will not display any images or audio’s from the connected PS4. The TV model could be compatible, however, if the device is experiencing an issue with its operating system, this can cause conflict with it receiving a signal from your PS4.

Reason 4. PS4 firmware

The PS4 blinking Blue light can occur if your console’s firmware is outdated, or contains corrupted software that is instigating this issue when you come to connect your gaming device.

Reason 5. PS4 HDMI cable

If the HDMI cable that is connected to your PS4 and TV is not connected properly or damaged, this will prevent your PlayStation from establishing a signal with your display unit. You will only be able to see the PS4 blinking Blue light with no picture on your TV.

Once the PS4 flashing Blue light occurs, you won’t be able to access the functions on your console nor be able to utilise safe mode.

(Did you know; There was a signed agreement between Sony and Nintendo. This was to manufacture an ‘add on device’ that would be able to play CDs for the Nintendo console. However, the agreement fell through because of complications between the two companies regarding software licensing. It was after this that Sony released the first PlayStation in December 1994).

Reason 6. PS4 internal hard drive issue

The BLOD (Blue light of death) will occur on your PS4 if there is a problem with its internal hard drive.

Issues with the console’s hard drive transpire if there are faulty files downloaded on the device, or from human error over time.

If your PS4 is continuously showing you a blinking Blue light, the console has frozen during the start-up process. Steps will need to be taken to fix this problem on your console.
