    Westinghouse L2410NM Power supply?

    The symptoms are dead set. After looking into the circuits, there are 3 modules. A power supply, main board and a video board. I may or may not be using the right terms. The power supply is obvious. The board that all the LED strips attach to, I'm calling a video board. With the unit plugged into 110 vac and the video and main boards unplugged, I have 3 voltages coming from the power supply. 5vdc, 14vdc, 24vdc
    When I plug the two boards into the power supply, all 3 of those power supply voltages drop significantly. I have no schematic on this unit and the boards are not labeled as to where B+ voltages are located. I have replaced the 4 electrolytic caps that are on the video board.(2 looked slightly bulged at the top) I have not changed any caps on the power supply. I'm looking for further diagnostic steps to confirm why and where I'm loosing my voltages?
    Thanks for any help/ suggestions.

      So the above is the current page. The thread on the first page by BudM has the guide.

          Do the voltages on the power supply stay up if you just disconnect the inverter board?
          Post pictures of your boards.

              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...

              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...

              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...

              Russound CA4 Power Supply Repair
              by CMCM
              Hello Everybody,

              Trying to repair a power supply from a Russound CA4 Multizone Controller (picture attached)

              Russound no longer supports it but were kind enough to provide a schematic of the power supply (pdf attached).

              The outputs marked 12v and 20v are all measuring only 1v.

              The board is clicking, which I think means it is in something called hiccup mode when the flyback transformers switches because of an internal problem or something else on the board Overloading it.

              The capacitors physically look clean (no bludgesor leaks) and...
