PS4 won't turn on good power supply, good hard drive not BLOD

I was playing a game on my ps4, and it randomly turned off, no beeps nothing just a shut down, I checked power cord and port, the remote won’t turn it on, eso I took it to a repair shop to be diagnosed and they said they couldn’t find out what was wrong, and they checked the power supply and hard drive and it isn’t either of them, so they suggested buying a new ps4 and I guess I am unless if any one things they know whats wrong or had the same experience.
