    Apple 820-3115 Water Damage Repair

    Hi, i got an A1278 mid 2012 Macbook with Liquid damage.

    The only damaged area is around the Backlight driver. One cap has blown off and burned a trace. Did somebody fixed somethling like this already? I would replace all big caps because they all corrode away or are cracked. Something i should watch out for?

      I looked at the boardview and the corroded circuit seems to belong to Thunderbolt. My bigest concern is Q3880 which is the 4 pin bga flip die. I have a feeling that it is blown too. Also U5400 is missing 2 legs too. The parts are available but i dont want to waste money on this.

          Usually trying to fix Thunderbolt is a nightmare, a waste of time and won't be reliable. I'd just forget about it and get the motherboard to work without Thunderbolt.

              Stagg sms12p audio amp has water damage
              by edugimeno
              Hi! My friend just brought this audio amplifier/speaker fro his music band saying they realized its got no sound. Led powers up but there no sound at all
              I opened it and found 3 board. 2 of them are for input plugs and potentiometers, and the other larger board has the amplifiers for 2 large speakers that it drives
              There's also a large toroid transformer that feeds a lower voltage to the first 2 boards and a larger voltaje (36x2 rectified close to 100v) to the power board. The power board has the plugs for both speakers
              There is only one signal wire connecting the first boards...

              Lenovo IdeaPad 3 15IAU7 that suffered water damage
              by Joel Ohana
              Hi,

              I have a Lenovo IdeaPad 3 15IAU7 that suffered water damage. It doesn't turn on (white power light flashes when on button pressed), and the amber light flashes when plugged in.

              Symptoms:
              • Short detected – sparks appear when touching the charging port connection with board with a metal (even a multimeter probe).
              • Visible damage – after cleaning corrosion, I found 4 possibly burnt memory chips near PC3165, labeled UD5, UD6, UD7, and UD8.

              What are my next steps to diagnose and possibly repair it without replacing the entire board? Any guidance would be greatly...

              A2141 820-01700 Water Damage L8504 Damaged, U3100/U3200 power cycles UB300/UB400 5V .25A
              by abajor
              Like title says A2141 came in with Water Damage, customer desperately wants the data.

              The actual water ingress doesn't appear too bad it sat for a day but was very dusty internally. I have no idea why L8504 was arced there is no apparent moisture there or around the LVDS cable; however, the LVDS to screen screw studs had popped off at some point and somebody tried securing it with kapton tape.

              I had to create a micron wire pad jumper to reconnect the south side of the L8504 since the primary pad was blasted down to the vias.

              That said after cleaning up the...

              Apple Watch Charging Controller Schematics / Boardview - 820-02601
              by a_p3rson
              Hi there,

              I'm looking for anyone who might have information on Apple's embedded Apple Watch charging daughterboard, ID 820-02601. This is currently used by Anker in their Apple Watch charging products, but likely by other Apple partner brands as well.

              You can see the board referenced in ChargerLab's teardown of the Anker Y1811 3-in-1 MagSafe cube - they discuss the "Apple Watch wireless charging circuit" about 2/3rds down the page. It's not pictured, but the board ID reads 820-02601-A, which sure sounds like Apple.
              This daughterboard uses an interesting...
