Hey guys. I’m new here so hopefully I’m posting this in the right place. I have a PS4 cuh-1001a that I’m ready to take a hand grenade to. It has the WLOD and I can not figure out why. So this is everything I have did:
Tried multiple cables and and 2 different TVs
Replaced the hdmi port and made sure the pins were soldered and not bridged (I have a circuit board microscope)
Checked the continuity of the pins and their respective areas as to where they go. All checked out good.
Checked the continuity of the hdmi filtersThose are good. They aren’t bridged left to right. I have continuity front to back on both sides.
Replaced the ic chip with a known working one, no pins are bridged and I made sure to check for loose pins
Checked the caps, none are shorted to ground
Checked the diodes, none are shorted to ground
Pin 13 diode reads 0.6
NOW HERE IS WHAT I HAVE A HUNCH ON:
pin 13 resistor is reading OL while attached to motherboard. I made sure to flip the leads around and both ways read the same. Do I need to remove this resistor to get an accurate reading or is it smoked? I do have continuity between pin 13 and the right side of the pin 13 diode so I’m not sure if that means the resistor is good? Any help would be great!
