I just took my box apart to clean it and got the red ring. I tried everything to fix it but I noticed that my power supply will not power on green which it should in a red ring case right?

My older xbox works just fine on the power brick. I unplugged everything and put it back in I took it back apart unplugged the AV cables put them back in STILL nothing...

My main concern is the power supply on the Red Ringed. I can't even pull up the error code.

Sorry for the double post I posted this yesterday just saw this forum not thinking I just always go to gold...

Any Help Plz
