    Blown Capacitor in Hammerhead XRT Device

    I have a walkabout Hammerhead XRT Win XP Tablet PC with a blown capacitor on the motherboard. Can anyone help me to identify the value of this capacitor and also It will be very helpful if you can tell me if any other component it would have taken along with it.

    This happened when an induction motor was switched-on (connected to the same mains electrical/power line where the Hammerhead device was connected). Is there a possibility that it would have taken down other surrounding resistors/IC's along with it?

    Can somebody help me with the connector pin out of this connector on the back of Hammerhead XRT device. I want to connect it to LAN and but I don't have a dock with me. So the only way is to make a custom adapter for this connector to connect to network.

      dont use google.

      you need to remove the cap, clean the board,
      then see where that cap connected.
      if it goes into that chip, get a datasheet.
      because it may have an example circuit that shows the cap value.

      as for the dock, i dont see any magnetics, so you need more than a connector.

          Does anyone have a picture of Hammerhead XRT Motherboard PCB?. That would help me to identify the capacitor that is blown in my device.

              so, this is the chip next to the cap.

              so if he cap is connected to pin1 and ground then it's c3 (100uf 35v)
              and if it's not connected to pin1 then you still need foto's

                          Thanks stj, it was the 100uf 35 volt cap that was replaced and the device is working perfectly (7 months months since it was fixed) and no issues what so ever.

                          Sorry stj I should posted this in December 2015 itself when the device was fixed.
                          Many thanks for your solution.

                              Blown capacitor repair on MSI Radeon RX 5700 XT MECH OC
                              by MeetingIncapable
                              Hello,

                              I am new to repairing computer electronics, so excuse any mistakes I make.

                              A friend of mine had a broken graphics card (MSI Radeon RX 5700 XT MECH OC) and gave it to me. It does not power on or show any signs of life.
                              I identified what looks like the remains of a blown capacitor at the bottom of the board (see picture).

                              I wanted to replace the capacitor, but I have two questions:
                              • Does this repair have a chance of working? or is a blown capacitor a sign something else is wrong?
                              • How do I determine the rating/value of this capacitor? or something
                              ...
                              C103 is blown

                              Samsung C32HG70 - Blown Ceramic Capacitor (CP813)
                              by NuclearSpartan
                              Hi everyone,

                              I'm new to this, so I apologize for not providing enough details. Is there anything else I need to mention? I'm trying to learn more about electronic/board repairs and hopefully fix my own.

                              The only visible issue on my board is one capacitor, CP813, which appears to be labeled R 221k 2kV (possibly obsolete to B 221k 2kV now). My monitor hadn't shown any prior issues, although it is a few years old. Just before the capacitor popped, there was a high-pitched squeal for 2–3 seconds.

                              I don't see any other visible damage anywhere else on the board....

                              Repair of Sign WiFi Smart Plug PCB: SA-P302A v1.2 due to bad caps - with schematic
                              by Per Hansson
                              I have repaired a Sign WiFi Smart Plug with model number: SNSM-WASINGLE sold by Spares Nordic AB in Sweden.
                              The fault condition was that the device gave no signs of life: pressing the push button did not cycle the internal relay and the blue LED did not come on and it was not seen on the WiFi network.
                              The fault was very simple, capacitor C3 on the PCB with writing "KSJ" and "LOWESR" had literally blown its top off, after replacing it the device works fine again!

                              As I find linear high voltage regulator designs interesting I drew up the attached schematic...

                              by valvashon
                              My (legitimate) massage therapist gave this to me to try to fix last time I saw here. Complaint was that it simply wouldn't turn on anymore. B&B have a rediculous return policy where you have to make a 3 minute video showing what the problem is, etc. Rather than mess with that Dana let me take it to try to fix it.

                              Verified that it wouldn't turn on. Don't remember trying to charge it before I took it apart. Found that the motor turned freely. Pulled the battery connector apart to check the voltage and the battery voltage was good- fully charged in fact at 11.3 volts. Plugged battery...

                              Help identifying connector for ASUS 4090 Strix RGB LED connector
                              by 5mall5nail5
                              Hi All -

                              I had replaced my ASUS 4090 Strix cooler with a waterblock and put the stock cooler on the shelf. Was moving it and snagged my sweater on the connector and pulled the wires out of the pins on the RGB connector. I tried to get them back on but its too small so I opened the stamped pins and tried to solder but its not a good repair and the wire broke on reinstallation.

                              Looking to replace the connector on the cable side and get pins to crimp onto a new cable. Bought random JST and such but nothing is correct. Can anyone help identify the connector and possibly matching...
