    Thanks Budm
    Shall check main filter cap and get back to you, it does read around 450uF in-circuit using a cap meter.
    240v def coming into board across AC1 and AC2 via IEC kettle lead, 8A fuse, rocker switch, EMI filter, transformer.

      Found a shorted schokty diode SS310 (DD3), located under the cap immediately next to the transformer.

      What alternative can I use temporarily just to see if it gets it working?

        "Getting around 290v steady on the main filter cap though takes a few seconds to creep up to that reading"?
        Your incoming AC is 230VAC so the DCV between the two legs of the main filter cap should be around 325VDC. So verify that your meter is OK, the incoming AC is OK, and the main filter cap is OK.

              Reebok GT40s Treadmill power supply issue?

              Quite sure its the power board at fault.
              The treadmill does not power up, the LCD display flashes on and off, almost as though the power supply is cycling on and off.
              Getting around 290v steady on the main filter cap though takes a few seconds to creep up to that reading.
              Voltage reads about 8v on the rail to the display/control panel but keeps dropping (fluctuating around 6-8v), pretty sure this is not enough to drive the lcd /control panel but could be the power supply shutting down before the volts can get high enough.

              The power supply board and components look ok on inspection.

              There is an LED on the PS bd but it does not light up or flash - this I believe is used for troubleshooting.

              Would greatly appreciate any guidance.

                Samsug washing machine. Power supply DC41-00189a board issue
                by Soulzink
                Hi everyone,

                I am trying to fix a samsung washinmachine power supply main board.
                I already replaced it with another one to fix the machine but i want to try understand the issue with the old board.
                Therefore i hope to be able to get some help to explain what to check in order to troubleshoot.
                The power supply board reference is the following: DC41-00189a
                I have followed one thread (https://www.badcaps.net/forum/troubl...ingmachine-rel...

                Asus Probook P5440UF-XB74 power issue
                by GLISIT
                Hi all,

                TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!


                I'm experiencing a power issue on an Asus Probook P5440UF-XB74. Although I've worked with electronics and computers for decades, this is my first attempt at getting into motherboard-level component troubleshooting. Any help the community can provide is greatly appreciated!

                A few weeks ago I was using the laptop (on battery power) for a Zoom meeting. The battery was running very low (long meeting) but I wasn't worried about...

                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.

                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...

                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...
