Beeps only when eject button is pushed and wont power on

"Since you can only power the console for a moment (1 second) it sounds like the power supply has gone bad rather than loose solder joints under the APU (processor chip) as explained below:

Try this fix if a replacement power supply does not work, if it works you’ll know whether or not the APU (main processor chip) on the board has loose solder joints to the board or not.

If that does work, it’ll fix the problem temporarily but it will happen a few weeks or more later. For a long term fix the APU needs to be reflowed properly or even better reballed from a reputable console repair shop.

Loose solder joints under the APU occurs from dropping the console or the console overheating due to dust build up.

"When leaving my PS4 at home in my room as I left for university, I thought it would be safe. I came back a few days ago and I wanted to play some FIFA or Horizon, I plugged everything in correctly, when I pushed the power button no sound came out but the eject but made 2 quick beeps.

I hit the eject button multiple times buts still 2 beeps and nothing for the power button, I was gonna for 3 months, what must I do"
