LED Status (Xbox Original)

the color of the power led on boot can indicate specific issues solid red red this is letting you know the console is overheating clean it out, check the fan is working, and try again can also mean bad bios/eeprom or failed mod chip install solid green green (no video or eject) this is almost always a bad bios/eeprom flashing red red this indicate the bios/eeprom is bad, or has failed to load check the bios, look for trace damage, and if any mods were done perhaps reverse them first flashing green green this indicate the bios/eeprom is bad, or has failed to load check the bios, look for trace damage, and if any mods were done perhaps reverse them first flashing orange orange shorted or torn solder traces between chips check for solder splashes or trace damage flashing orange orange (fan spin 100% then off) overheating, or there may be an issue near the temperature sensor chip at location u6f1 flashing green green / orange orange this is the most common, and simply means there is no video cable connected sometimes the video out circuit or port is actually bad but its normally just the cable there is a potential the smc (a pic chip that handles low level control and av cable detection) is bad, but it is much more likely you just have a bad av cable if you do not have a cable present, you can just ground pin 19 for example to set the cable detection into outputting ntsc mono and bypassing the orange flashing light flashing red red / orange orange this is typical of power failure the main large capacitors, the super capacitor or the regulators are often bad first try a recap (perhaps even full recap) of the console this is often accompanied by frag (so green on/off/on/off/on) then flashing red/orange flashing red 50% red 50% / green 50% green 50% unfortunately, this is a general system failure and can be many things swap your power capacitors and super capacitor used on the clock if problems still persist inspect the board for trace damage, any signs of burned or bulging capacitors or blown components known causes bad network ic with silkscreen ics bad power circuit below the debug header bottom left, with the 6502 regulator and large caps flashing red 75% red 75% / green 25% green 25% the hdd is bad, or cables/power to it flashing red 25% red 25% / green 75% green 75% the dvd is bad, or cables/power to it boot loop x3 then flashing red red / green green usually bad bios/eeprom
