Hi everyone, I bought a damaged a2338 MacBook pro with water damage and I'm hoping to learn how to fix it. I've worked on electronic for a long time for never attempted repairing water damaged components. The charge port connection on the motherboard along with the USBC connector is burnt. I'm hoping this is worth my effort and I'm not wasting my time. I've sourced some parts but first I was wondering if there was a way to check to see if it was Beyond repair if there was a fried CPU. Is there anything I should check before I order parts?

Short on ppbus. Taking 3a at 1v and nothing is heating up. I have at least 3 pads that are badly burnt from capacitors. Ive scraped (at least attempted to) not sure how good I did? Are these possibly containing internal shorts? Do you think they need to be scraped more?... -
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... -
Small water damage, cleaned it.
Shorted CL002, i removed it carefully with soldering iron, now it has voltage.
5v instant 180ma and then 100ma stable. I didn't found cycling voltage nor shorts in the motherboard.
I don't have pp5v_s2 because uc300 does not get enable pin from u8100 (it gets VIN). pp5v_s2 is not shorted, nor enable pin line.
PP3V3_S2 OK
PP3V3_S2_UPC OK
PP1V5_VLDOINT_MPMU OK
PP3V3_AON OK
PP1V8_AON OK
PP1V25_S2 OK
PP1V8_S2 OK
PP1V8_S2SW_VDD1 OK
PP3V8_AON OK
u8100 did not have corrosion... -
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... -
