    Apple iMac 21.5 Delta ADP-200DFB Power Supply

    Anyone ever worked with this supply before? I've got a non working one with no visible burn marks anywhere. Have replaced both startup capacitors with new ones but I'm not getting any power or trickle voltage at all on the imac. Fuse is fine. Can hear it make some noise when plugged into mains.

              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...

              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...

              >>> Troubleshooting Delta Power MAX 500ATX ATX power supply
              by dragon3x
              Hi, this is for troubleshooting and, hopefully, repairing a Delta Power psu
              that is still quite new, as it worked OK for some months until it failed.
              At the time I was not into power supply electronics; it was put
              aside and a new power supply installed inside the computer. Also at the time
              power supplies were half the price of today's.

              On the PCB there are a D339 and 7500B chips.

              I have found that schematics with these 2 chips (see included file).
              Does it represent the actual circuit of the MAX-500ATX, I cannot tell.

              Some measurements,...
