    Re: Ubiquitiu 24 port POE. Help Identify Diode 3pin)

    Found D334 on the POE daughterboard to be faulty. This powers Port 12. Will replace on Friday. Then I hope that's all and it should be fixed 100%
    This Switch has had some serious damage to it by previous owner. Luckily I've fixed pretty much all of it.

        Not really, but some things in UK have to be bought in pack of 10. Which is OK if it's a regular repair of the model.
        I bou6the switch for around £100
        The CPU cost £35 from AliExpress, delivered.
        The LAN Transformer and TRV from Farnel (expensive place to buy because they charge a standard Handling Fee of £9 RIP OFF). Cost me £21.
        The equivalent Diode (5 pack) from eBay £5 (good price).
        So all round I reckon it's worth it, if I keep or sell.
        But from experience, in this case they're relatively easy to repair. Just the parts are a pain. Especially the LAN Transformer because I only found 1 product which has the correct coil configuration, others are opposite.

        UPDATE.
        it's ALL FULLY working now.

          I was asking the cost of a new switch although I appreciate your feedback about the cost of the repair parts

            New is near £400.
            24 port POE 250w. Just checked eBay.

              PS5 HDMI port diode reading?
              by SuperAman
              I did an hdmi port repair for a PS5 and I lost the small diode z71 SOD923 on the back of the port. I did a trace repair for pin 19 of the port as well. Without the diode I get no display at all. I tried replacing the diode twice but after I get flux on it the marking comes off so I can't tell if I have it on the right orientation. When I measure I get a reading of 1(open) and 923 in diode mode. Is 923 a normal reading for these and also which side should the reading be with regards to the arrow on the board?...

              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...

              AUO M270QAN01 - identify diode?
              by jjne
              Hi,

              I have a small number of monitors based on the above panel and am working through them. I have at least two with a single, burned-out diode. From what I can see it's something like DI428 or DII428 or DH428. Here's a picture of a working one.

              Can anyone identify this please? Based on the number 428 it may be a shottky or a Zener according to Google. The device in question is D105.

              ETA I can confirm that the number is definitely 428 (I took a video which revealed a better image), the DII appears to be a maker's mark. There's also a code 1G. Looking around...

              Identify replacement diode
              by jezzaaaa
              I'm trying to find a replacement diode for one that has gone short.

              I have a generic USB charger that went short circuit to ground on 5V. I found that one of a pair of identical diodes in parallel (and in series with transformer secondary winding) has gone short in both directions, so I suspect it's bad. The marking is CSRS1045, which I believe is a low barrier Schottky with max current 10A and max reverse 45V. I found a spec sheet for CSRS1045-A that has same specs and also says 350mV drop when forward biased.

              I can't find the exact part number for sale. Similar...

              Questions About The Numark MixDeck Onboard DC Port
              by TurcoLoco
              Hello all,
              I have a Numark MixDeck from 2011. The power supply seems OK but the DC port within the deck itself seems broken or loose.
              The device will not power on until the DC connector is inserted and then turned a little counterclockwise then it works but if you touch the cord, poof!

              I am guessing the cube shaped DC port on the board is bad and needs to be replace?
              Does anyone know what this part is called so I can check on DigiKey or somewhere?
              TIA...
