Hi guys, my PS4 was doing this a few months ago but started working a few days ago, and now it's doing it again.
So when I turn it on, it does two beeps, blue light pulses, clicks and whirrs, turns white, clicks and whirrs, pulses blue, beeps quickly 4 times then turns white again. It sounds like it's trying, and clicks quietly every now and then, but doesn't do anything else. I've bought a new HDMI cable for it but that's not the problem.
It's refurbished and I bought it in November from GameStop, and the PS4 call center has sent me a box to send it back, but I've been battling with GameStop for about 3 months now to get my receipt.
