    Insignia ns-32e440a13 LED TV

    This unit has sound but no back light.

    Trouble shooting I found that D51 the diode in the LED drive boost circuit, between the Inductor and C17 output cap, is shorted.

    It is a SMD part and has two markings on it. C310 & CH2d. Searching the web, I have come up blank. Does anyone have any info on it.

    Thanks

      For testing that boost converter you can use through hole Schottky Diode 200~400V rating with 2~3A rating.

          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...

          Finding replacement diode iPad Pro 3rd gen A1701
          by asr
          Hello, I am looking for help to replace a damaged diode. The tristar was replaced and a diode was damaged in the process. I have a picture of the diode but dont have an exact donor. I mostly have macbooks for donors and only a few ipad and iphone boards. Diode part number: DSF01S30SCAP
          Im not sure where to find the ipad board number. Anybody have an idea where else this diode is used on other boards? Thanks....

          TV backlight zener diode
          by unimatrix93
          Hello everyone, I'm repairing an LG TV backlight and I noticed some strange behavior when I touching the backlight strip with a missing Zener diode.

          So I replaced the leds on the strips and they seemingly working fine, but soon as I touch the strip which has a missing Zener diode the whole backlight turns off for a few seconds and then turns back on.

          Is this caused by the missing diode? If so what kind of zener diode should I use to replace it?.
          ​​​​
          The led strips has 9 6V leds.

          Lenovo S145 -15iwl vcore inductor warm.. looking with oscilloscope there is a spike.
          by Bartoloni
          Hi, i have a Lenovo S145 that after 20 seconds shutdown and restart (it's working correctly on thse 20 seconds)
          everything seems ok, but on Vcore inductor ( this is an i3 with just 1 switching power supply for CPU)

          there is an output to teh CPU with a spike.. seems that inductor can't handle the input...
          replaced the capacitor (330) and the inductor (R15) without any change
          any idea? very thank you!

          input of the inductor seems as usual... only strange thing is that the upper/lower voltages seems to be 21V (main power line is 19.3) ... but not sure this...

          How to read inductor specs?
          by badcap111
          I have a broken samsung galaxy s10 with missing inductor. I want to replace the missing inductor and I have found some vendors. But I don't understand how to read the specifications of the inductor. The specs are:

          INDUCTOR-SMD;470NH,20%,2520,T0.8,0.029OH

          I understand that the inductor is 470 nH with 20% margin, and the size is 2520 or 1008 (imperial measure), but what do T0.8,0.0290OH mean? I can't find any explanation on the web.
