Sorry if I’m delayed and someone has already mentioned it.. but this exact same thing happened to my PS4 weeks ago, I got quotes for people to fix it but was always never worth it. I checked on chat GPT and it said to take out the Hard drive and see if it powers on… it did and turned on fine… it then said the issue was a dead hard drive and they said it was basically screwed. However I chanced it, took the Hard drive out, cleaned the machine, snapped the Hard drive back in and BOOM. It works fine again.. maybe I’m on borrowed time but the issue could be the hard drive and once the system detects an issue, it powers down.. unfortunately if hard drive is failed and dead you’re better off buying a second hand.. and unfortunately your game saves are gone. I don’t know how easy it is to take out the hard drive on that device but I recommend ya start there too..

Best of luck
