    need help with Apple AcBel 1PC36

    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. i dont have the right resistor for that so i was improvising with a common resistor.

    also it feels warm like normal power supplys and when i plug it in the G4
    it starts for a few seconds then shuts off. when i remove the power supply all pins seem normal except the 12v becomes 9v for while then returns to normal.

    so im not sure if its something on the g4 shutting down or shorting the power supply or something wrong on the power supply.
    its a difficult scale where to me since its fresh caps,consistent meter readings at the plug and board to me its working but the motherboard i see no threads about it shutting down the powersupply. i also read i need the monitor plugged in to keep it on but i cant confirm this.
    any help will be most appreciated.

    Please post some pictures of both side of the switching power supply board we might be able to help you figure out what is going on with it

      Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
      by Tynan Dill
      I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

      Upon bringing it home and plugging it up, it showed a standby light.

      I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

      The screen seems to blackout and stay black, but with a flashlight I can see the display.

      With my Playstation 4 connected via HDMI, and running a game I can hear sound.

      Assuming...

      HP Power Supply 6632A: Fast Mode vs Normal Mode?
      by cook
      FAST MODE vs NORMAL MODE

      I have recently acquired a HP 6632A DC power supply. I am just beginning to use it and I have been reading the manuals for it. It is the first power supply I have ever owned or used. I am a very beginner hobbyist and do not have an engineering background, as may be obvious by my question...

      I can't seem to understand what the actual use is for the 'Fast Mode' or the 'Normal Mode' on the power supply. Although the manual states what the two modes do from a engineering/technical standpoint, I don't know enough to understand what it all means,...

      Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply
      by sam_sam_sam
      I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

      One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...

      Apple Watch Charging Controller Schematics / Boardview - 820-02601
      by a_p3rson
      Hi there,

      I'm looking for anyone who might have information on Apple's embedded Apple Watch charging daughterboard, ID 820-02601. This is currently used by Anker in their Apple Watch charging products, but likely by other Apple partner brands as well.

      You can see the board referenced in ChargerLab's teardown of the Anker Y1811 3-in-1 MagSafe cube - they discuss the "Apple Watch wireless charging circuit" about 2/3rds down the page. It's not pictured, but the board ID reads 820-02601-A, which sure sounds like Apple.
      This daughterboard uses an interesting...

      Modification to a ZD-987 desoldering/soldering station using a external switching power supply
      by sam_sam_sam
      I have been working on this concept for quite some time now with limited success but recently I found a switching power supply that is setup for the voltage that this soldering station needs to operate at however it also needs part of the secondary circuit from the original switching power because you need several voltage rails

      I once tried to get a ZD-915 desoldering station to work on a 18 volt battery power supply but unfortunately things did not go well but I did find a work around but I might try this idea again but going at a little differently more about this another time...
