    D-Link DIR615

    The other day a friend bought me some stuff in the stuff was a nice D-Link router.
    Plugged it in with correct power supply and flicked the switch on the side.
    No go.

    Tested the power supply that puts out the right volts.
    Tested power supply plugged into the device that stayed at 0.2 the whole time.

    Now I'm Unsure what to do next.

    None of the IC's look fried or discolored.

    written on the board.

      Is the polarity of the DC plug is correct on the power supply you are using? Is the center pin positive or negative? You can also check the resistance of the center pin of the DC input jack and Ground to see if it shows low Ohm.

        Test the adapter with a load - 5volts? try a 6 volt bulb or perhaps some leds?

          I have got another similar power pack and I have plugged in both to the device.
          the power pack also powers my other router that I have laying about.

          power packs all worked. router I had laying about worked.

          So that rules out power pack problems don't it?

          My guess is someone at one point in time has plugged in the wrong power pack.

              I used a spare dlink router power pack I had from my other router known to work.
              so it does rule out power pack.

                Re: D-Link DIR615

                Could be a bad joint on the connector if it buzzes? Pictures will need to be a
                great deal better if you want people to suggest what to test next.

                  Re: D-Link DIR615

                  Check if anything gets hot on the board while the power adapter is plugged in.
                  Or as budm suggested, check the resistance between ground and the positive pin on the power jack (with the power adapter plugged, of course). Let us know what resistance you get.

                      some more photos.

                      I have notice that the buzz will take awhile to come on.
                      when you switch off from the power point it sounds like a motor slowing down you hear a tick tick tick.


                      not sure about these photos I think they got down sized when they were sent to me via mms.

                      also i replaced the caps closest to the power supply.

                            with the psu connected, look if those two small square chips in the upper right corner are hot, or look burned.

                              do you mean 105 & 112 or the smd inductors below it?

                                Well, nothing is going to get hot because the switching power supply will go into shutdown mode to protect itself from trying to feed current into shorted circuits. You still do not tell us the resistance reading at the DC input pin jack (no power supply attached to it) as shown in post 3 and 9.
                                There at least 3 switching regulator power supplies on the board.

                                    There you go, now you just have to start isolating the loads and find out where the short/shorts is/are.

                                        Just a done a reading of the first switch and it was only doing 0.0 0.1 0.2 0.3

                                        In a loop.

                                          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...

                                          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...

                                          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...

                                          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...
