The Flashing Red Lights on Xbox 360 Console
If you’ve ever had 1 to 4 flashing LED red lights show up on your Xbox 360, then you may have noticed the difference. In many cases, you can turn on your Xbox 360 to be faced with 4 flashing lights. If your Xbox has all four lit up, then it means there’s an error in your audio and/or video connection. Make sure all the appropriate connections are secure, your Xbox should be connected to your TV and your power adaptor should be providing power to your console.
If you check all your connections and find that they’re all in their appropriate positions then turn on your console only to be confronted with the same flashing lights, then I’d recommend you changed or purchased new cables in order to verify whether it’s your cables that are causing the problem.
If you turn on your Xbox 360 and are confronted with 3 flashing lights, then it means you have a hardware failure problem with your console. The first step that you should take is to check your consoles power supply unit to make sure all cables are plugged in correctly and securely. Double check the connections to make sure that they’re all securely in their appropriate positions.
If you turn on your Xbox 360 and see 2 flashing red lights, then it means your console has cooling issues with one of your systems main chips, which can be either the CPU or GPU. One thing you can try to rectify this issue is to switch your system off for some time and allow it to cool down and then move your console to a well ventilated location.
