    Dune Duo multimedia player Power supply

    Hi,

    I need a bit of help. I have a Dune Duo, The psu has the fuse blown, maybe the bridge rectifier as well, but the problem is that the ic controller is damage so I cant read the markings. Anybody can help me identify the chip. This power supply is used in allot of dune boxes. If anybody can take a picture of the psu so I can identify the chip I would be grateful. Or where Can I get another PSU.

    Thank you.

      the missing piece is in the unit or on that board - shake them over a table

          The whole problem is because of this glue!

              I can´t find it. its somewhere in another dimension by now. I remove the IC, I thought that maybe on the other side would be some markings, but no luck it just some generic number I think something like L04 02

                  you think it died because of the glue? I can replace the fuse and the bridge rectifier, but unless I change this, I don't think would do much good. Would be a shame to throw away a perfectly otherwise working unit because of one compontent.

                      It is more likely that the small electrolytic cap next to the ic is bad. Post a clear picture of the bottom of the board as well as a clear view of the trace side under the ic.

                          You should be able to iD your chip.

                          I assume no responsibility for any stupid suggestions I might post.

                              Thank you. I´ll try it there. For now I bought a power supply board module 12v 6A and its working fine, get a little hot, but its ok so far.

                                  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...

                                  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...
