    Truecam H7 - component missing in micro usb circuit

    Hi there...

    i got myself a broken dashcam on ebay with a super cap instead of a battery.

    There was no amperage gettin into it... after some measurements i found out there was a loose component next to the micro usb port. in my oppinion i´ts somthing like a voltage regulator.... i need help by replacing the component marked with "BY" or "BV" . i´m not trying to solder it in again because its loiking bad. think its blown too...

    can somebody help me?










    Black = GND
    Red = 5V
    BLue = ???
    Green = positive V ???

    thanks

          Help me identify the missing component... Sound to light circuit
          by edugimeno
          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...

          9th Gen Dell Optiplex Micro PC motherboard repair: Short Circuit?
          by Geeker007
          Hi All, I have a 9th Gen Dell Optiplex micro PC motherboard which doesn't power on. When I connect the motherboard with power adapter, it goes into safe mode and turns off. So from info I have gathered online, it looks like there is a short circuit on the motherboard. So can you guys help me with figuring out the issue?

          I am new to electronics repair, so my queries could be naive but I am ready to learn.

          So I have a multimeter and a solder with me. But I can try to get a variable voltage power supply with a thermal camera as well. From what I seen online, best way is...

          by alfredomfr1
          12v pin is shorted to ground in the LCD board (1st picture) if the LVDS cable is disconnected, 12v are OK in the Main Board (2nd Picture)

          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.

          820-02020 PPBUS_AON missing
          by ugamazing
          Board had no history of liquid; unsure of drop history, but no signs of damage of any kind worth noting.

          Charger sitting at 5v/0a. PPBUS is at 1.9v-0.9v steady cycle (peaks, drains, loops). Confirmed CHGR_EN_MVR is missing, but DCIN was reaching ISL just fine, so replaced ISL--no change at all. Confirmed pp3v8_aon is also missing--and being unsure *exactly* which signal appears first (or if they are simultaneous), I inspected PMU/U8100 area and found no shorts, but also found PP3V8_AON_MPMU_ISNS_VIN missing (not shorted). Replaced U8100 just in case (have had them fail in weird ways),...
