    Acbel api2fs34

    Hello guys. I just bought one Acbel g5 PSU "spares or repair" and of course, it needs repairing. I've already read some of the posts related to this specific PSU, but I still haven't found the issue. The behaviour is the following:
    I connect the AC, jumper the green and the black wire, the relays clicks twice and the fans make a bit of a spin. and then stop. In the brief moment in which it does that, I measured the voltages on the output. +3.3V Check. +5V. Check. 12V No-go.
    I've already measured the MOS, most of the zeners and there is no buldging capacitor. Maybe I've skipped some critical zener?
    Can anyone of you give me some direction here?

    Thank you in advance!

      Macbook Pro A1989 820-00850-a not powering on
      by Simplebeans
      Hey guys i just got myself a Macbook Pro A1989 820-00850-a 2018, the seller said they had spilt liquid over it and since then it has never turned on.

      I am using a Apple 61W USB-C Power Adapter and USB-C Charge Cable and on my USB tester i can see when i plug into the power i get around 5.21V and stays at 0.24amps. I am currently testing disconnected from the battery and only plugged into the USB-C Charge Cable.

      When opening the machine I was greeted with corrosion on, in and around, in particular the U3100 (USB-C PORT CONTROLLER XA) and U3200 (USB-C PORT CONTROLLER XB)...

      Definitive technology SC 2000 subwoofer amp's power supply clicking and popping
      by JimBanville
      The sub developed a constant popping every couple seconds from woofer and power LED flickering with nothing but wall AC connected. Connecting an audio cable didn't change anything. It doesn't play but a second or two of audio in between the pops.
      Opened it up and discovered the power supply is making a faint clicking or ticking sound.
      I measured the amp's output to the woofer and it pulses up to 50mv DC to be driver. The pulses coincide with the power supply ticking/clicking.
      I measured the power supply output going to the amp board and it too has this pulsing. Voltage cycles...

      need help with Apple AcBel 1PC36
      by jetblue
      hi,i recently recapped a non responsive acbel 1pc36 power supply. i need to know what is the plugged in state for this supply with no jumper wire on the on plug pins.
      is it normal for the fans to come on and meter readings on the plug to be normal? or does the start pin need to be bridged to get any readings from the plug?

      it seems like its stuck on on and not standby from what i read on the threads.
      its not cycloning only when i bridge the other set of pins will it do that but im not sure if its because im not plugging the pins right because after a while it stops....

      Surface Pro 7 1866 won't turn on...
      by titomno2
      Hi guys,
      Just have a surface tablet pro 7 (type 1866) with motherboard JALAMA_ICL_MB DV:2.0.
      Can't power on the surface tablet, no reaction on the button whatever the charger (working) is plugged in or not.
      After dissassembly I made a physical inspection without seeing any damaged component (nothing visible at least).

      Made measurement:
      With battery (low voltage 7.9V) the led D7013 is on (red)
      Charging seems odd and decided to let it apart and working only with DC input.

      With power supply 15VDC (white light on the charging cable).
      D7013...
