    Xbox 360 Slim PSU Zener diode ID

    Hello
    Been a while since I posted on here, hope everyone doing well. Recently I acquired a few xbox 360s and one of them had a terrible fan noise inside the PSU. The fan wire is normally glued down to the PCB with some high temp silicone. Not an issue to remove since the wire is barely glued, however this one was buried too deep, so stupid me grabbed the needle nose pliers not realizing there was a zener diode under that damn silicon, so I ripped that sucker in half. Can someone please help me identify the correct zener diode? All I see is D1 and no other markings on the PCB and just 41 on zener diode. Thanks for you help.

      are you sure it's a zener?
      maybe it's 4148?

          I think you are correct, I put the damn thing under the microscope and found 8 on the other side. I can't see any other numbers as glass was shattered.
          Can someone please verify?

              The component designation should have been "ZD" if it was a Zener, so I think stj's guess is the best you will get

                  I removed the broken diode and cleaned the PCB there are no "ZD" or other Zener markings on the PCB. Already replaced it with 4148 and it's all good to go. Should use my brain more often. lol
                  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.

                      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...

                      What zener diode might fix the sound on Maestro Mayhem gaming chair?
                      by nev1001
                      Hi, I'm looking for a bit of help trying to fix the audio unit from a Maestro Mayhem 4.1 gaming chair please.

                      The chair has a few speakers and vibration motors. All was well, for a while, but now the sound is gone.

                      It may be significant that I discovered my son was powering it with a 19V laptop charger when it should run on 12V - it did fully work, for bit.

                      I think an issue could be a zener diode (or capacitor) which has shorted out.

                      The board's bluetooth input still works, the vibration motors are working, so is the line out socket but not the...

                      Element 32 inches tv (ELEFW328B) Unknown component: Diode or zener?
                      by Vincenzo2
                      My Element 32 inches tv (ELEFW328B) lost it's backlight (confirmed with a flashlight test) and the connector on the PCB (it has one board that has a processor chip, switch mode power supply, and backlight circuit) that has the two wires that go to the backlight LED strips has a very low voltage (28-29 volts) when turned ON, in my opinion.

                      Started testing components and found an SMD diode or zener that is shorted (even zero fusing resistors read a few tens of milliohms, while this thing reads zero).

                      I put some pictures here to show that it is labeled "M7"....

                      Corsair RM1000e - Help identify 5VSB Zener diode
                      by hobostove
                      Hey there guys. I've got a Corsair power supply that's come across my bench dead. I usually don't mess with power supplies, but it's a slow week so I'm giving it a whirl.

                      Taking it apart I heard a screw rattling around inside, and when I got it apart I found a couple blown components near what I think is the 5VSB area.

                      There's a 22ohm resistor that's melted and open, but it still has the bands.

                      The other part is a zener diode and it's top went to jesus, so I can't read the marking.

                      It looks like the diode connects the source and drain of a TNY284...
