Why Is My PS4 Blinking Blue Light? Fix PS4 Blue Light Of Death

We all know the dreaded blinking blue light on the PS4 that signals something has gone wrong. This blue light of death can be frustrating, leaving you unable to use your console.

The good news is, that there are several things you can try yourself to fix a PS4 with a blinking blue light before taking it in for repair.

Why Is My PS4 Blinking Blue Light?

This guide will walk you through the common causes and solutions so you can get back to gaming as quickly as possible.

What Causes the PS4 Blinking Blue Light?

Before we get into fixes, let’s look at why you may be seeing this ominous glowing blue:

• Software Glitches: Random bugs or crashes in the PS4’s software can cause booting issues. This is commonly fixed by rebooting or reinstalling software.
• Hardware Failure: If the power supply, GPU, RAM or Blu-ray drive fails, it can stop the PS4 from booting properly and trigger the blue light. Hardware failures often require repair or replacement.
• Overheating: Heat build-up causes system instability. Ensure your PS4 has adequate ventilation and is kept in a cool area.
• CMOS Battery: The PS4 has an internal CMOS battery which can die over time and prevent booting. This battery can be replaced.

Fix PS4 Blue Light Of Death

Here are some quick troubleshooting steps to attempt first before deeper diagnostic and repair:

Reboot It

• Turn off the PS4 fully by holding the power button for 10 seconds until it beeps twice
• Unplug all cables from the back of the console
• Wait 2 minutes
• Reconnect all cables
• Turn PS4 back on

This simple reboot solves many temporary software glitches causing blue lights.

Use Safe Mode

• Hold the power button until the second beep (7 seconds) to launch safe mode
• Connect controller with USB
• Try rebuilding the database and other safe mode options to fix the software

Replace HDMI Cable

• Use different HDMI cables between PS4 and TV
• Check both ends for bent or broken pins

Check Connections

• Ensure power, HDMI, and all other cables are inserted fully and securely on both ends

Inspect and CleanPorts

• Dust buildup in ports can affect connectivity
• Use a can of compressed air to clean out any debris in ports

Update Software

• Connect PS4 to the internet
• Download the latest system software update
• Can also reinitialize PS4 with the latest software

These simple steps resolve the blue light issue for many users by addressing temporary glitches before they require advanced repair.

Advanced Troubleshooting and Fixes

For persistent blinking blue lights, further troubleshooting is needed:

Power Supply Issues

• Bulging capacitors
• Burnt smell indicating a short circuit
• No sign of life when pressing the power button

Likely a non-functional power supply unable to boot PS4. Replace with new PSU designed for PS4.

Internal Hardware Failures

• Attempt safe mode troubleshooting
• If still having issues, internal components like GPU, RAM, or Blu-ray drive may be defective
• Requires opening PS4 case and testing each component
• Repair or replace any defective parts

Resolve Overheating

• Regularly clean dust buildup from vents using a vacuum
• Ensure clearance on all sides for airflow
• Test operation without case to check if overheating
• Consider adding a cooling stand or external fans
• Repaste CPU and GPU with fresh thermal paste

CMOS Battery Replacement

• After extended gaming sessions, the internal CMOS battery can die
• Preventing PS4 from turning on and giving blue light
• Locate the battery on the circuit board after opening the case
• Remove the old battery, and replace it with the new CR2032 CMOS battery

While advanced fixes require more effort, they can resolve persistent blinking blue light problems relating to hardware failure and overheating.

Still Won’t Turn On? Last Resort Options

If you have tried all other troubleshooting without success, last resort options include:

• Take to a professional PS4 repair technician for diagnosis and servicing.
• Contact Sony about possible warranty coverage or paid repair options.
• Purchase a replacement PS4 system or consider upgrading to PS5.

Getting the PS4 repaired or replaced can allow you to keep gaming if all self-fixes are unsuccessful.

Before taking these options, double-check all cables, reboot, and try safe mode as the simplest solutions are sometimes overlooked!

Frequently Asked Questions:

Here are answers to some common questions about fixing the blinking blue light on a PS4:

• What if my PS4 turns on but then turns off with a blue light?

This points to overheating causing system instability. Thoroughly clean dust buildup internally and externally. Check thermal paste on CPU/GPU. Test operation with case open. Add a cooling stand and external fans.

• My PS4 controller won’t connect when I get the blue light. Why?

Flashing blue light means PS4 isn’t booting fully, so controller wireless sync fails. Use a wired connection in the safe mode instead.

• I replaced my PS4 HDD. Did this cause the blinking blue light?

Possibly. Recheck HDD was inserted properly and compatible with PS4. Try reconnecting the original HDD to test. Faulty storage devices can affect booting.

• How can I tell if my PSU is faulty?

Signs include loud coil whine from the PSU, burnt smell, bulging/leaking capacitors, the system instantly powering off, or failure to power on entirely. Test with a multimeter or replace the PSU as needed.

• Why won’t safe mode work when I have the blue light?

Can’t access safe mode if hardware fails. For example, defective RAM prevents the system from booting to safe mode. Identify and replace faulty hardware instead.

• Fixed PS4 blue light once now back again. Why?

Intermittent issues suggest temperature fluctuations or HDD issues. Rule out overheating first. Check SMART readings on HDD using PC and replace if faults are found.
