    Delta dps-300sb doesn,t start no output no led

    just thought I would leave this tip for anyone with the above psu.
    in my case this psu would run perfectly one day and not start the next but leave it for a few hours and it would start again.
    when it wasn't working the green l.e.d. on the back of the psu remained out the fan did not turn and there was no power output.
    everything inside the psu looked clean, no blown caps etc.

    turned out to be C914 was under capacitance when removed and tested... replacing it fixed the psu

    found more info on this website

          In the 5VSB circuit? Or in the PWM circuit?

              MSI Delta DELTA 15 A5EFK-008 Notebook 15 Specification for Upgrade or Repair
              by Document Archive
              This specification for the MSI Delta DELTA 15 A5EFK-008 Notebook can be useful for upgrading or repairing a laptop that is not working. As a community we are working through our specifications to add valuable data like the DELTA 15 A5EFK-008 boardview and DELTA 15 A5EFK-008 schematic. Our users have donated over 1 million documents which are being added to the site. This page will be updated soon with additional information. Alternatively you can request additional help from our users directly on the relevant badcaps forum. Please note that we offer no warranties that any specification, datasheet,...

              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...

              Calculating ESR from tan delta -- tan delta's dependence on capacitance
              by Junkrepair
              I'm finally recapping my Soyo K7VX6 motherboard (aka KT600 Dragon Ultra) and replacing Sacon SZ-series caps. The Sacon SZ datasheet provides a spec for tan delta, but not for ESR, while the candidate replacement caps are specified in terms of ESR.

              I found this nice little description of the conversion:

              Calculating capacitor ESR from Tan(delta)
              https://forum.digikey.com/t/calculat...-from-tan/2633

              It mentions that a general spec for tan delta has to be adjusted for the specific capacitance before plugging tan delta into the formula...

              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...
