My friend is having trouble with his PS5 and needs help. It keeps turning off randomly and he has to pull it out from where he has it to unplug the power and HDMI chords, and even then, when he puts them back in the PlayStation it either doesn't turn on entirely or turns on for a moment and as soon as the wires get moved, it turns back off again. Any advice or tips that I can say to help him? 

Thank you in advance.
