    Finding smd led to replace

    Hello,
    I got this fuel indicator board that has one color of the circled led not working, do you know what kind of led is it (it measures approximately 2x3mm) and if it can be replaced with a soldering iron ?
    Do you also know the kind of the other four leds above ?

    Many thanks!

      How much voltage going into it, and what are the 2 colours supposed to be

        The colours are green and red, don't know how much voltage probably not more than 5V, if needed to know I will try to measure it.
        The other four leds are all green.

          Can you measure the size of the LED. It is likely a plain bi-color SMD LED, guessing 3.0*2.5mm but there is bigger 3.2*2.7mm etc.
          example: Kingbright APB3025ESGC-F01

          Once you know the size, a suitable part can be found in your locale.

          A multimeter on diode-test can check if both LED's are working, or if the green one is 3.2V or 2.1V type if it is working.

            The voltage on red led is 1.8V but strangely the voltage on green led is 5V.
            Do you believe it is normal or there is something wrong ?

              Is it no harm to replace with capacitor without ripple current rating?
              by chth96
              When I tried to repair LG 29 inch CRT TV, I found that the ESR value of samyoung SMS capacitor(160v 2.2uf), which is very close to D1879 transistor, is 6 ohm.


              Judging from above ESR Meter Table,I think It is necessary to replace this sms capacitor.So I visited local electronics shop,and I purchased 160v 2.2uf rubycon YK capacitor.
              But when I browse through rubycon YK datasheet,I found that there is no ripple current rating for 160v 2.2uf specification. But On the contrary, I found 39 mA ripple current rating for 160v 2.2uf SMS capacitor.
              Rubycon YK DataSheet (b...

              Opinions/Advice on Do/Should I replace ALL Electrolytic Capacitors on old equipment?
              by RetroComputingGrotto
              I've just been repairing some (very) old speakers with a loud hum that occurred as soon as you powered them on regardless if any actual audio is played through them. I work in a School so it's 99% likey that the Teachers have hardly ever turned the power off on them for well over 10+ years.



              As you can see the top large capacitor on the right has a bulge on the top so defincately needs replacing. As the one next to it is exactly the same capacity and voltage I planned to replace them both.


              What is your advice/opinion on whether or not on old(er)...

              Is it okay to replace 1/2 watt resistor with 1 watt resistor in AC/DC adapter?
              by chth96
              I have purchased an 100-240v AC/5v 2a DC adaptor from aliexpress,and a month ago It smelled burning when I plugin it powerstrip.
              Since then, This AC/DC adaptor have been out of order.
              But A few days ago,I replace 0.5 watt resistor with 1 watt resistor(1ohm) in this adapter.
              After replacing resistor,It succeed to recharge all of android phone.And When I measure voltage on the two pins of USB port,It shows 5.5v
              Is it okay to replace 1/2 watt resistor with 1 watt resistor in AC/DC adapter?
              And Is there any possibility that it will suddenly explode as well as to be out...

              Conformal coating on Samsung U32D970 monitor PSU, do I need to replace after repair?
              by psyduck
              I have a Samsung U32D970 monitor from 2015 I pulled out of the bad hardware pile that turned on and then turned itself back off after a few minutes of use and refused to turn back on. The PSU has part number BN44-00786A, and I found a couple posts about one that had blown with damage to the MOSFETs and PWM controller - but nothing about intermittent failures. I started a new thread and said that I would refresh the solder joints on the board to see if it was just a bad connection and possibly replace the PWM and PFC ICs. I then asked what my next course of action would be after those steps. I...

              G703GXR Dead CPU? shorted CPU power mofset replace, missing DRAMRST#
              by pc_okay
              Hello friends,

              I replace a shorted mofset (PU8104), now laptop is starting but no display, stopping at DRAMRST#.
              Resistance to ground on PL8104 is around 1-2 ohm, quite low but voltage seems ok 0.995V

              Any help would be appreciated it's a nice laptop !

              Thanks. 😃
