    Corsair CX500M Missing PG signal

    I got this PSU today with missing PG signal after is turned on all other voltages are fine. PSU will not release PG voltage untile main power SW is turned instantly off then back on again while psu is working, same will happen in pc. Pc will not show image on screen until you flip the PSU sw off/on while is working,after that pc can stay on for hours at full load. Dose anybody have any idea what coud go wrong since there is no schematics, im in process of replacing all the caps on high and low side.

    Tnx

      Get rid of the small Jun Fu and CapXon caps on the controller boards. No guarantees this will fix your problem, but it's a good start, IMO.

          Well, based on experience, sometimes bad bulk capacitor can cause lost PG signal in cwt platform.
          At least that happens in two enermax 500.
          Lost PG, try to replace anything in secondary side, no good.
          And, random replace in primary, and bam, PG suddenly appear when i replace the bulk caps.

          Weird..

              Asus Zenbook UX431DA / UM431D - Ryzen - missing PWM Fan Signal.
              by gurj1979
              Hey guys.

              Need help with this one.
              Fan not spinning due to missing PWN Fan signal.
              Also 5 seconds from powering up it freezes, unless in BIOS.
              But as soon as Windows starts to load, it will freeze.
              CPU is COLD / Room temp when it freezes.

              I've replaced the CPU, same problem.
              Replaced SIO/KBC IT8987e and reprogrammed - same problem.
              Replaced fan - same problem.
              Replaced flex cable from board to daughterboard (which has fan connector on it) - same problem.
              Checked the Thermal sensors around CPU and Board to the SIO/KBC and...

              sony vaio mbx-247, missing S5_ON signal
              by mohamed mm
              Hi everyone, I hope you are having a good day.

              I have a laptop sony Vaio, DA0HK1MB6E0, MBX-247. REV: E

              The laptop suddenly shut down as the owner told me, so I did the normal check there is no short but the laptop it's not powering up and there is no light when I connect the adapter because there is no battery.

              so I checked.
              pu9:
              Vin: 19v

              Ldo: 4.89v

              Ref:1.99v

              Vcc: 4.89v

              Vdd: 4.89v

              output

              3.3v pcu.

              EN2: 4.89v

              but No              ...

              Surface 7 - missing S3 sleep signal, S4 present but weird
              by Prott
              Hey fellow Badcappers
              I am troubleshooting Surface 7 board (rev 1.0) which was working great until it experienced a short circuit due to a bad screen.

              Now it's missing SLP_S3 signal. Everything in the power on sequence works properly up until that signal.

              - The resistance to ground on the SLP_S3 line is >50 kOhms.
              - No shorts on any powerrails that I can find.
              - I get a proper clock signal on the RTC crystal (XTAL_2P) once the Surface gets power.
              - SLP_S4 is, suprisingly, present, but it looks very weird (jump up to 2 V for about...
