    A1398 Component Question

    I have a MacBook Pro A1398; the logic board has a metal screw terminal that connects the logic board to the case. The board map indicates it is a ground.

    The component is BR0901.

    I can not tell from the schematic what function this part plays. The board is already grounded through the power supply, so I don't understand the purpose of this terminal.

    For those of you with access to this map, the part is on page 9 (at B6).

    Can anyone tell me what role this particular component plays and, what the potential hazards are if this component is missing?

    Mine has broken off. I don't intend to replace it unless I absolutely have to.

      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.

      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:...

      2007 Macbook logic board fault
      by tony359
      Good day all,

      I got a 2007 MacBook from a friend. The fan was not working so it was overheating.
      Once the fan was swapped, I installed an OS and it worked fine.

      The board had quite a few corroded spots so I removed it, touched those spots with a soldering iron, washed the board in PCB cleaning fluid (I've done that many times), rinsed it with distilled water, dried it etc.

      Unfortunately it doesn't work anymore. It does turn on, fan spins, power LED turns on. But no picture.

      If I see that right, I have missed VCORE on L7100 (page 59)....
