      It might be a dual mosfet like a Alpha & Omega AO6402A

          It might be a single mosfet, are pins 1,2,5,6 connected together?
          Is that number 4T6V ? is there a dash above the V ?

              hi, thanks for your answer
              YES 1,2,5,6 are connected together on the pcb.
              YES i read 4T6V but coulnd'nt find nothing with this code.
              NO, i can't see any dash above the V.. but on the side there is what seems "1B"

                          I guess my chosen word went wrong. "seem".

                          Come here on Great Forum not only want to learn electronics, but also I've want to learn to be good on conversation/writing on post. Sometimes i didn't really understand if without help g**gle translate, sometime the translator make more worst as well.

                              mosfet does not switch on when 3v are applied to gate. so i have no ground to my motor.
                              btw thanks to all for the answers.
                              i wonder how you could identify this component, since i tried on smd lookup marking codes table and found nothing.
                              thanks again

                              sometimes our english is not the best i know, (i am not english native too.. ) but i hope we can understand each other

                                  Mostly 99% work on laptop repair, from there i knowing alpha omega's mosfet. Also have several time see mark with "dash" and number/letter with orientation anticlockwise 90 degree on the end body package. BUT totally newbie at all, that's way reading many threads for learn.

                                          Indentifying an old exploded cap.
                                          by Crystaleyes
                                          Hi all.

                                          A friend asked me to help remove the mains hum from an old 60's or 70's portable record player.
                                          The brand is Motoplay, which is an obscure Brazilain brand.

                                          Anyway. One of the caps seemingly decided to launch itself into outer space and exploded in the process.

                                          It appears to have been a ceramic disc with coloured stripes, and from the bits I could find and see, it appeared to be either violet or silver on top, followed by some brown, then some orange.

                                          It definitely had silver, brown orange going down, but the brown...

                                          hI there!
                                          Im trying to help a friend repairing a large, real-sized short-circuit robot.
                                          This is remotely controlled and has a 2 way voice send/receive. Also while the hidden operator is talking, the red bulb inside the "mouth" should flash according to the sound
                                          Some other technician used to service it and he was fired leaving all the repairs unfinished and no documentation at all.

                                          What I found is a sound receiver, a speaker, and a wire directly to the mought bulb (a normal motorbike 5W 12V bulb).
                                          So I bought a simple 2X30W amplifier to feed the loudspeaker...

                                          repairing an EVGA 1080
                                          by TheDevastatedOne
                                          Hello, I am repairing an EVGA 1080 that appears to run fine with the stadard VGA drivers in windows 10 but when you load the Nvidia drivers there are artifacts.
                                          I think I have narrowed the problem down to a component that is located at Q3302 (There are a # of schematics here https://www.gadget-manual.com/nvidia-geforce/ for similar 1080's but not specifically the EVGA ones)

                                          But everyone I've asked is not 100% certain what the part in question is located at Q3302 and is marked with "AG4X"
                                          So I am including some photos.
                                          I have possibly narrowed it down...

                                          by QuestionLegionaire
                                          I have a Samsung ue55b7070 which won't turn on but makes a clicking noise.

                                          After having a look around, the noise and dim sound like buzz/fizz, seems to be coming from a film capacitor marked "105k 450v S 938 FMPE" However, I am unable to find out the exact specifications of the capacitor and was wondering if anybody could help.

I dont want to break it, I tried squeezing the white plastic and that didn't work and I tried pushing the black part down and that didn't work maybe somebody knows the secret trick, maybe i'm just not holding my mouth right or something...
