Hi, ive got this PS4 1-981-472-21 (motherboard) for repair. PS4 will start for 1 second and then shuts down, pressing power button will not start it again. You must unplug power cord and then it will again start for 1 second. What is normal APU resistance on 6 coils? I have 0.7 Ohm APU shorted? ( read FUBAR ) |

do you know normal resistance to GND on APU coils? i only have 0.7 OHM , seams to low for me. i know some of gtx 1000 series have less than 1 ohm resistance to GND , but that APU is AMD chip. Anyone? |
