My Xbox One S keeps on turning off after a minute

Hello,

I've been experiencing problems with my Xbox and wanted some advice. Every-time I turn it on, it does the chime like usual but then doesn't display any signal and after about 1 minute. I've had to buy an Xbox Series S because of the price of a repair but only now I've looked at my vast library of games and decided to try and get this fixed. I'm using the cables from my Series S which works perfectly fine but theres no change. My TV isn't the problem and I'm not on the wrong HDMI. The issue has been persisting since 2019. Also I've tried all the methods of resetting it. Tell me if its worth repairing or if I'm wasting my time

:)
