    Cosel ZUW25 2415

    I took this off a donor board. I am trying to see if the unit is functional. I tried giving it power 30V. applied to V+ and V-.

    I could not get an output. I checked for output on V+ V- and combinations thereof with COM.

    The board is potted. Does anybody know how to test these for functionality?

    Here is the datasheet.

    It's a 24V to +/-15V DC converter, so why did you power it from a 30V source? You most likely killed it.

      It's rated for 18-36V, so 30V is fine.

      There is a remote on/off pin that needs to be grounded to enable the output. Have you connected that pin?

        Thank you for the response. The datasheet says you can go up to 36 V.

          Thank you for the response. I did ground it by connecting V- to the RC pin. I get absolutely nothing. Unless that's not how you ground it.

            Onkyo HT-R390 no sound output, video output ok
            by FrancescoV
            Good morning everyone,
            I'm trying to repair an onkyo ht-r390 that has no sound output, despite the volume being at maximum, the rest seems to work; the video output signal (coming from an hdmi input) is present, but the audio is absent. Similar situation if I send an audio signal from any input I have no output.

            The firmware reported is the following:
            M:1.00/11107BLP
            D:?.??/????????
            O:1.00/11107AL

            The DSP firmware given the question marks seems corrupt.

            On the BCHDM-0678 - 25140678 - QPWBCHDM0678A0 board the chip that usually seems...

            NTE Electronics “NTE5251K” Zener Diode 9.1V @ 50W Do-5.5% Want to build a 9.1 output from a 9.6 lipo4 battery pack
            by sam_sam_sam
            I have bought this Zener Diode for this project what size and wattage resistor value do I need to use to get near 50 watt output
            I bought this from an eBay seller but unfortunately they only had one

            I bought three from Vetco Electronics these are Sylvania ECG5185A 9.1@10w A to Stud what size and watt resistor do I need to use to get near 10 watt output
            I bought three of from them to also make battery packs with this output power limit in mind

            I want to use this battery pack and turn it into a 9.1 output battery pack output to eliminate using 9 volt battery...

            Corsair CX750M [Model 75-002019] - burned output toroid inductor
            by momaka
            Looks like I may need a little help from the PSU experts (or anyone really! ) I have a Corsair CX750M (Model 75-002019) that I picked up for free about 4 years ago. This is the PSU:



            So here’s what’s strange about this one: it appears to work normally (normal output voltages) and any PC is stable with it. However, after a while (typically 10-20 minutes, but time can vary depending on the load), there is a sweetish smell of burned magnet wire insulation emanating from the PSU. Upon opening the PSU after this happened (many times), I was able to confirm...

            Troubleshooting PFC with SPC1012T not raising output
            by CoppellTVRepair
            It has been a long while since I posted here to ask anything....hope you can help.

            I have this Samsung power supply that uses SPC1012T as driver for the PFC and it's giving me a problem that I can't narrow down though I've troubleshooted and fixed hundreds of boards similar circuits.

            I am attaching a schematic from a different Samsung board, but the topography is very very similar if not 100% the same and it uses SPC1012T, which BTW is a pinout match to UCC28063 for which there's plenty of information. I haven't confirmed they are functional equivalents, but I strongly...

            Magnum IA.100 Amplifier Switches on, No Output, Possible Input Side fault?
            by flibidy
            I have here a Magnum IA.100 which belongs to my parents.



            The unit powers on & when the relay kicks in, you get a pop from the speakers (this might sound weird but is usual behavior for this amp). However, you get nothing coming through it from any of the inputs & no pops and crackls from any of the controls.


            Because of the sound from the speaker when the amp turns on I have assumed that the output section probably works but I could be wrong & I'm not sure how to test that side of things further.


            What Ive done........
