Xbox 360 red dot of death

I have a limited edition MW3 Xbox 360 that’s has the red dot of death but I’m unsure of how to fix the problem is it the power brick or is it to do with something else . It would be greatly appreciated if anyone could help

More than likely you need reball to the CPU/GPU!

Is it a slim or the fat xbox 360 like with the hardrive sticking out

No its his southbridge that gone bad just throw it away because if you reball the southbridge all the components around the southbridge will go bad after reballing so it cheaper just to get a new 1

just throw the motherboard away the southbridge has died and just swap cases with another console

No it the southbridge that gone bad just throw it away not worth relowing or reballing southbridge because all the components around southdrige can go bad after reball
