    This iPad pro logic board is not repairable, right?

    iPad Pro 11" 2nd model.
    Itunes No. 9 error occurred, so I removed NAND. And I checked the components.
    Among the rails that power the NAND, PP1V8_EXT_SW1 is abnormal. The diode value is very low at 0.040. This power rail is the rail that comes from the CPU, not the PMIC, and on a normal logic board, the diode value is 0.300.

    When I inject an electric current into this rail, the CPU and encryption chip generate heat.
    Should I say the CPU is damaged?

      Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
      by Tynan Dill
      I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

      Upon bringing it home and plugging it up, it showed a standby light.

      I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

      The screen seems to blackout and stay black, but with a flashlight I can see the display.

      With my Playstation 4 connected via HDMI, and running a game I can hear sound.

      Assuming...

      HP Pavilion 15-eh Board DAG7HAMB8F0 - CPU throttling to 0.4GHz (PROCHOT_EXT) and black screen
      by m1ch43lzm
      Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
      Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

      Upgrading a Samsung ue55nu7096u with logic board from an ue55ru7105k -- good idea?
      by ohren
      I hope this is the right forum to post in despite not technically being a repair, but still a question of swapping boards.

      I thought I'd explore the possibility to upgrade an existing working Samsung ue55nu7096u with the logic board (and power board if needed) of a newer model (ue55ru7105k) of the same size and appearance (and resolution). The reason being I'd like the extra inputs of that board including component in, an extra HDMI port and bluetooth. Its panel is broken so I have no use for the board otherwise.

      The models launched in 2018 and 2019 respectively....

      LG 60PK550 Logic Control Board EBR63450301
      by Yanleb
      Hi all, I just want to share the repair of my 60PK550-UA TV set.

      The TV set was powering on, just no image. After verification, nothing wrong on the YSus or ZSus boards. Nothing wrong on the main board either.

      But I noticed that the LED was not flashing on the Logic Control Board. This is an EBR63450301. The LED is supposed to flash even with all the flat cables disconnected, with only the power cable attached.

      All the voltages measured at the electrolytic capacitors on the board were good. From top left to bottom right:
      C57: 3.30V
      C61:...

      Ipad 8th gen logic board making buzzing noises
      by Rab1
      Just to ask what could possibly be causing the logic board to make low buzzing sounds? Thanks.
