3 red lights means you power supply is not fully pluged in
you can find that straight from xbox .com/support

Thanks for the help guys im trying

telogen wrote under the x clamps are these black things. There will be a bunch of gunk on it so you clean that off and put 2 pennies rapped in electrical tape and put the x clamp back on. Then you do the towel trick till you get 2 red rings. Let the xbox cool down, turn it on and there you go it works

I'm sorry, but this is very bad advice. Doing this causes more damage to the console. Does it work at times? Sure. Forcing it to overheat like this warps the board and often times temporarily allows the cracked solder connections under the GPU to touch.

This is by no means a reflow. To reflow lead-free solder, it has to get up to around 230C. A reflow station is required to do this. Wrapping the 360 in a towel gets it up to 100C tops before the system cuts power to prevent a fire.

I find that consoles which have been subjected to "youtube fixes" are often way harder to fix. I've had a lot of toweled/overheated 360s which needed replacement GPUs (reball).

OP, please get the secondary error code when you get the 3rrod and/or 2rrod.
