Fix Xbox 360 Power Supply Yellow Light Problem – Best Solutions

Your Xbox 360 turns on but the screen remains blank and you are presented with three flashing lights in the front of your console in which one of which is a yellow one.

This indicates that there has been a power failure and your Xbox requires repairs or replacement to prevent further damage. I am also a culprit of this issue and faced this issue many times. I will let you know about my experience and how I got out of it.

While there may be no signs of damage to the outer casing of your Xbox, it is likely that internal components were damaged by the power surge which caused the yellow light error code on your power supply unit (PSU).

How Does The Power Supply Work?

The power supply unit in an Xbox 360 provides power to the console. It also includes a fan to keep the internal components cool. The power supply has a light on it that indicates the status of the unit.

The power source is operating properly if the LED is green. If the light is yellow, then there may be a problem with the power supply.

Why did my Xbox 360 power supply light turn yellow?

There are a few reasons why your power supply light may have turned yellow. The most common reason is that the power supply is not getting enough power from the outlet. A problem with the power cord is another option. If the cord is frayed or damaged, it may not be able to provide enough power to the console.

Finally, it’s possible that there is an issue with the power supply itself. If you suspect this is the case, you should contact Microsoft for assistance.

How To Test The PSU

There are a few ways that you can test your PSU. The first is to use a multimeter. You’ll want to set your multimeter to the DC voltage setting and put the probes on the +12V and GND pins. If you get a reading of 12V, then your PSU is working properly.
Another way to test your PSU is to plug it into your Xbox 360 and turn it on. If the power supply light is green, then your PSU is working properly.
If your PSU is not working properly, then you may need to replace it.

Power cord issue

The first thing you should do if your Xbox 360 power supply has a yellow light problem is to check the cord. Make sure it’s plugged in properly and that there are no loose connections.

If the cord appears to be fine, unplug it from the console and plug it back in. If the light is still yellow, try a different outlet.

Overheating problem

The overheating problem with the Xbox 360 power supply is a common issue. Most likely, the cause is dust buildup on the cooling fins of the power supply. The dust restricts airflow and causes the power supply to overheat. You can clean the dust off the power supply using a can of compressed air.

Hold the can upside down and spray the dust away from the cooling fins. Be sure to hold the can upright so that you don’t get any liquid on the power supply.

If you do get liquid on the power supply, unplug it immediately and let it dry for at least 24 hours before plugging it back in. Once you’ve cleaned the dust off, your power supply should be good as new!

Repairing the power supply

In order to solve the issue of the Xbox 360 Power Supply Yellow Light Problem, you need to follow the steps below.

1. Unplug the power cord from the back of the Xbox 360.
2. Remove the four screws from the bottom of the power supply.
3. Carefully lift the top half of the power supply case off, being careful not to break any of the small plastic clips that hold it in place.
4. Inside, you’ll see a large transformer and a smaller circuit board. The transformer is what provides power to the unit, while the circuit board regulates that power.
5. Check both for signs of burns or other damage. If either looks damaged, replace the entire power supply unit.
6. Reassemble the power supply unit and plug it back into the Xbox 360.
7. Turn on the Xbox 360 and check for proper operation.


Why is the power supply light on my Xbox yellow?

You won’t be able to send or receive any energy with your power supply. You will have to purchase a new power supply in this case (check the price on Amazon). On the other hand, you’ll need to get your Xbox One repaired if the light goes yellow and your console is still not functioning.
