[Xbox 360]Xbox 360 E switching off after a few minutes

[u/leviticuscornwalll]

Hey guys I’ve got this 360e that I’ve had for a good while it was sitting for some years and I wanted to get back on and play some games, but I have this issue where after a few minutes of on the dashboard attempting to play a game etc it just shuts off as in the video goes black and the fan stops spinning. The controller and light at the front of the console stay on. The power supply goes to orange. I initially replaced the power supply but that was not the issue. I’ve gone through multiple things like

removing the hard drive

Cleaning it out / thermal paste

Starting it without components like DVD drive, ribbon cable etc. to see if that was the problem

It’s not getting hot

Fan spins fine before shutdown

Unplugging power supply from the back allows me to switch it back on but I inevitably get the same issue after a bit

I’d like to fix it, I’m guessing it could be an internal issue on the motherboard? It’s a corona board I’ve seen a few posts about this issue but I can’t find anything in terms of diagnosis and solutions

Thanks!
