    another G5/661-3350 query

    hello to all ,
    i just joined up and did a quick search for some information relating to the G5 20" swmps .
    i noticed in one thread that a schematic was asked for , this is about where i am at ... or a parts list .

    in addition to the half-fistful of bad caps that i replaced , D10 has turned itself into a piece of wire (no magic smoke) .
    i believe this diode is in one of the smaller supplies (standby/always on perhaps) . it is in association with the TOP244Y driver IC .

    the oem number is T2D46 .
    i have tried to cross reference this critter to no avail .
    without a schematic i cannot readily ascertain if it is a zener or a fast rectifier .
    does anybody have any information on this device ?

    thanks in advance .

      What Zener Diodes on a Linear Power Supply
      by caspian
      Dear members,

      I have a linear variable power supply with unknown brand name that I used for voltage injection.
      Then it failed. I discovered that its transistors (Q1 and Q2) are shorted.
      In addition, I discovered that its zener diodes are defective.
      I can replace the burned transistors.
      But I do not know the model of the zener diodes. the model number is not marked on the zener diodes.
      Therefore, I cannot replace the zener diodes.
      I do not want to test the zener diodes in a test circuit to discover their model or value.
      no schematics are available...

      On M-Audio AV40 active studio speaker's two zener diodes get really hot.
      by Dvsr
      Hi. I need help from wiser guys. I am amateur in electronics and can't figure this out by myself.
      I bought faulty speakers, M-Audio AV40's. Other speaker has all the electronics in it and the other speaker is just passive one powered by the other speaker's amp. Original problem with the speakers was loud buzzing. I figured out that there is something wrong with the capacitors. I went ahead and replaced every electrolytic capacitor on the PCB. The caps are good quality and have the same values as the original ones.
      After replacing the caps I started testing out the speaker. It seemed...

      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...

      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...

      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.
