Editing Troubleshooting Guide

= 🧰 Xbox 360 / Console Troubleshooting Guide =

'''Note:'''  
This guide is mainly for ''unmodded consoles'' or ''modded consoles that were working fine but suddenly stopped working'' without you changing anything.

== ⚡ Step 1: Check the basics ==
Before anything else, make sure you’ve checked the following:

* Power cable is fully plugged in.  
* HDMI or AV cable is firmly connected.  
  '''Tip:'''  Xenon models will show '''4 red lights''' if no AV cable is connected.

== 🔌 Step 2: Does the console power on? ==

'''If NO:'''
* Check the '''power supply LED'''.

**• Light is green:**  
Try powering on using a '''controller''' instead of the console button.  
If using a wireless controller, make sure it’s paired to the console.  
If it turns on now, you may have a '''faulty power button''' — [[Power Button Repair Guide|click here to learn how to test and repair it]].

**• Light is off or red:**  
1. Disconnect power for '''10–20 seconds''', then reconnect.  
2. If it’s still the same, the '''power supply fuse''' may be blown or the '''PSU is faulty'''.  
Try a replacement PSU or fuse.  
If there’s no light or it stays red even when disconnected from the console, the PSU is likely dead.

== 💡 Step 3: Console turns on but nothing happens ==

If the console powers up but doesn’t boot:

* Does it start but show '''no video'''?
  * Check the HDMI or AV '''port for damage'''.
  * If still no picture:
    * On '''HDMI models''', try using a '''yellow/white/red AV cable''' instead.
    * If you get video through AV, your '''HANA chip''' might need replacing.
  * If you have a '''modded console''', try powering on  then press Eject this disables plugins that could stop it booting.

== 🔴 Step 4: Console shows an error or red lights ==

If your console boots to an '''error code''' or '''3 red lights''',
