I've had my ps4 for 3 years, and 3 months ago, it cut off, and the power would not come back on.
As I researched the problem, I found that it was my power supply that went nuts. I called around to local companies, but unfortunately they either couldnt help, or they cost hundreds of dollars to fix. Luckily I found this site, and they not only had the materials I needed, but they had a step by step Manual as well.
It was surprisingly easy. The only part that was challenging was getting the tools I needed. I ordered on a thursday, and my shipment arrived that Saturday. It took 15 minutes.
My ps4 works now!
It's better (and cheaper) to fix things yourself.
