    STR - Y6476 testing

    Hi there wondering if someone could tell me if its possible to test the above component out of circuit using a multimeter.i have removed it from the power supply board of my lcd tv as there was burning around the legs on the back of the circuit board.also where is the best place to get a replacement in the uk.
    thank you.

      Re: STR - Y6476 testing

      thats a power ic,these normally fail VCC to ground,just identify the legs from datasheet,you want to see high resistance between the 2 legs (vcc and ground)
      fixed so far...376 lg lcd tv's,24 onn tv;s,24 panasonic lcd,16 jvc lcd,12 marshall jcm800 amps,refurb of various disco equipment lighting,old style disco decks ,and a flymo!

      please let us know if everything works ok if your tv gets fixed, as it will be and aid for anyone else having the same problem and wishing to fix it.it would save people clogging up this site with topics that are duplicated,and can be found easily using the search function.,and taking up valuable space.enjoy your fixed tv!,hopefully!

          hi there.
          thank you for your reply.i tested between vcc and ground as you said ,and it did show high resistance,so i guess its ok.
          thanks again.

              also burning like that can be due to cracked solder joints,seen it a million times,turning the light off and flexing the board with an insulated tool may show it up as a spark.

                  op amp circuit function?
                  by Alimash
                  Hi,
                  I am repairing a ups which doesn't turn on ,it has the following ICs:
                  SG3525 used to drive inverter mosfets.
                  couple of uc3483, one for the power supply and another to drive a big mosfet at the output stage(i think the technique is called boost)
                  A LM358 and TL074 for control mechanism and of course the uController.

                  The SG3525 is shutting down every time the ups is turned on.
                  I want your help to know the function of LM358 and TL074 in the system.
                  I reverse engineered the LM358 circuit and i think that one of the block(A) is used for battery level...

                  Fixing the Charge Circuit of the Batteries of the DC Motor
                  by Astonished
                  Hi friends of electronics

                  What you see in the video and pictures attached is the circuit for charging the batteries of a DC motor.

                  The problem is that this circuit cannot charge the batteries (3 1800mAH NiMH batteries) any more. When the circuit was OK, its green LEDs lit up one at a time to show that the batteries have charged more. But now that the circuit is flawed, LEDs light up as you see in the video and at the same time successive beeps are heard.

                  Please help me fix this circuit.

                  (the datasheet of the IC: https://pdf.datasheet.live/28...

                  trying to fix a 6V 0.5A T1 (Transformer) AD050120T2 power supply
                  by Tarot Superstars

                  Hi. I am trying to fix a 6V 5A power supply that would was used a lot.
                  I want to fix it partly for learning, and part because I don't want to buy a new one.

                  It has distinctive smell of burning but not seen obvious burned components yet. I'm not sure where the fuse is.
                  I tested the only slightly bulged capactitor (out of circuit) and it measured normal capacitance and ESR.
                  Everything else was tested in circuit with a multimeter.

                  In circuit tests
                  I tested the large diodes underside and they seem fine.

                  I tested...

                  Short Circuit tester
                  by Tarot Superstars
                  Hello.
                  I have seen a short circuit tester made with 3 * 9V batteries, a voltage limiter component and a resistor connected to the probes of a multimeter.
                  The theory is that the meter becomes sensitive enough to read very low resistances and the lowest resistance to ground on a circuit is likely to be a short circuit in that area.

                  MSI B250 Gaming M3 Short circuit in CPU power supply circuit
                  by M1NEBLANK SHOW
                  Hello. MSI B250 Gaming M3 board, short-circuit on the power supply. Found a problematic mosfet VQ1
                  (N-PK616BA_PDFN8-HF) soldered it out - short circuit is gone. I replaced VQ1 + VQ5 (N-PK632BA_PDFN8-HF). VQ1 was replaced with PK618. After starting attempt VQ1 is lit again. What can be the problem? In the driver?
