    DA0ZPVMBAD0 rev d Mainboard - blank screen issue

    I have the DA0ZPVMBAD0 rev d logic board and it doesn't boot up. I see all the voltages are okay. So I suspect the issue is bios.

    When I power on with fn+ esc the blue light start blinking on mainboard.

    I guess its a good sign. As all the voltages are okay and also charging indicates orange light when battery connected, I think it confirm that the EC bios is okay. So I ignored the ec and flashed main bios with 32mb bin file provided in the link below. But the condition is same.

    Do we need to modify this bios file before flash?

          Samsung HG49EE690 Hospitality TV reboot issue Mainboard BN94-11086A
          by alltvrepairs
          Hi,

          I have 3 of these TVs for repair with same problem of going to standby after around 10minutes and start again continuously. I have tried a new SPI 25Q40 but fault remains. Am suspecting a CPU problem as it gets a bit hotter than I expect.
          This seems to be a common problem in these models. I am 100% sure it is a mainboard issue as I have fitted a spare from a normal TV from a UE40K5607 and stays on (diplay inverted but I managed to rotate in SM using a different display).


          Any help appreciated!...

          PS5 Dualsense controller stick drift a mainboard issue?
          by dbuergi
          Hi all,

          I got a controller where the left stick was moving left all the time (-1.00 at calibration tool). Even after changing to hall effect sticks it stayed the same and reset and all others things didn't help.
          I removed the stick again and even without it calibration tool shows a movement to the left. Anybody knows where the fault can come from? Maybe any bridges or damaged SMD components?

          Sony KDL-65W850C is this a Mainboard issue ??
          by mmartell
          This sat around for quite some time after the backlights died with the six blink error code. I bought replacement strips and eventually swapped them in.

          Backlights appear to be working fine now. However the tv only powers on with the "Sony" logo for about two seconds after which it goes away and the panel with backlights stay powered for about twenty more seconds then it shuts off. Tv can only be powered again after power cycling at the outlet.

          It will not program via usb, the stick flashes but there is never any indication that it has entered programming...

          MacBook Air A2337 (820-02016) USB-C Port Issue – Only Works in One Orientation (CC Line Problem?)
          by rounin
          Hi everyone,

          I'm working on a MacBook Air 2020 (A2337, board 820-02016) and running into a strange USB-C issue. I've gone through quite a bit of testing and part replacement, but I'm stuck — hoping someone here can shed some light.

          🛠 Original Issue
          The machine initially wouldn't negotiate 20V over USB-C — stuck at 5V.
          Diagnosis showed PP1V5_UPC0_LDO_CORE shorted to ground.

          I replaced U3100 (UF400) using a donor board (A2179), and the machine powers on fine now.

          ⚠️ New Problem: One USB-C Port Only Works in One Orientation...
