    FNIRSI DSO-TC4 owners, please help...

    I’m asking if someone who has a DSO-TC4 Fnirsi component tester could upload the contents of its internal memory for me, since mine arrived with a corrupted USB memory and a factory reset or firmware upgrade doesn’t help. Also, the device makes a strange clicking noise when it’s turned off but still connected to USB. Thanks in advance — anyone interested can check out the link bellow.

      here is another one with same problem found on Youtube:

      I have replaced the Winbond flash chip (I found a model with the same specifications), although it is not exactly the same.
      I flashed it, the device powers on, and after that I flashed both BIN files again — the process completed successfully, but unfortunately the problem remains the same.
      Is there anything else I can do? I would really like to repair this device.
      For now I know that Flash chip is not problem.

          The main firmware is located in the AT32F403AVGT7 controller.

                  It will be 100% locked from reading and you will not get its contents (dump) from it.

                              Liquid damaged macbook A1466 fan spins, but doesn't turn on.
                              by redbaron1007
                              I got a tricky one today in the form of a macbook air A1466 820-00165-A that will recognize the charger and turn the light green then back to orange and the fan will spin constantly, but the system won't power on. The screen never turns on, it doesn't make the bong noise it's supposed to, and pressing the power button doesn't do anything. When I took the board out to visibly inspect it I only found one spot of corrosion on the bios IC. I pulled the chip, cleaned it and the area with IPA and put fresh solder on both and put the bios chip back on, but when I went to test it again it still does the...

                              Lenovo y520-15ikbm most of the time doesn't turn on
                              by melvinvdb
                              Hello,

                              I've repaired a few laptops in my life but this time my own laptop died😂.
                              Funny enough this one is a bit tough on me.
                              It doesn't turn on (most of the time).
                              Model: Lenovo y520-15ikbm (NM-391).

                              The only way to make it turn on is:
                              1) unplug battery + charger + rtc (seems irrelevant)
                              2) wait a minute
                              3) plug battery/charger in
                              4) on charger plugin, laptop turns on by itself. On battery plugin you have to press power button. Sometimes nothing happens and you have to try again.
                              5) when it turns on it also displays POST...

                              Lenovo IdeaPad 3 15ITL6 doesn't start
                              by Victor Petrovich
                              I have laptop Lenovo IdeaPad 3 15ITL6 with Intel Core i3-1115G4. When I press the start button, LED light on the start button starts blinking 12 times, then stops and after some time starts blinking 12 times again. When it stops, all voltages are down.

                              The motherboard is HS460 HS560 HS760 NM-D471 Rev: 2.0
                              S/N: PF3Q0WTF

                              The motherboard is not mine, also there were corrosion on the board which I cleaned.

                              Methods of fixing like fully turning off the motherboard or starting only with adapter doesn't work. All testing were did only with adapter on.
                              ...

                              ASRock B560 Pro4 doesn't start
                              by johnnys25s
                              Hy there.
                              I have a ASRock b560 Pro4 MoBo that doesn't power up anymore after CPU swap. I used (my) CPU to test another (broken) board and after put it back, my board doesn't start. I've tested that CPU again but it's ok. I even bought another one for testing. I also have 2 PSU for tests. NO bent pins and no mechanical damage.
                              I have different voltages on the board (in some places) but it doesn't start, at all.
                              I have the schematic but I don't know what to do exactly with it. I have some skills and I can measure things. I need help to try to repair it. Thank you.

                              Hello from France

                              My daughter spill some water on her laptop... Lenovo Ideapad Gaming 3 15ACH6, and she doesn't seen anything wrong after just remove the water with towel.

                              Then, later the laptop won't start anymore.

                              I've made a basic troubleshoot with my own laptop (same series)

                              So, the computer battery is totaly out. With my battery, the computer works !

                              But, with PSU connected, the latptop detect the power.. the harware led white is on, the amber one too and on the screen there is a 'batt charging' message.

                              But...
