I have this board that was sent in for water damage. When I plugged it in the trackpad would click and the ammeter read 19.8v and 0.55A The only components that looked like they had any kind of liquid damage were C8412 , C7660 and Q7660. I replaced C7660 and C8412 and put the board in the...

I have this board that doesn't look to have any liquid damage and is stuck at 5v and 0.21amps on all 4 ports. There isn't any boot loop just a steady 5v. I was getting 1.4v on PP3v3_G3H and so far I have replaced U6903, R6910-13, C6910/11/13/15/16 and D6902 . I still get the same voltage but I...

Hi, I have this A1706 that has some damage to the corners of the topcase and may need to be replaced. I found some top cases that have only a keyboard so I would need to transfer over the touchbar and everything else. I was wondering how difficult it is to remove the touchbar from the original...

I have this board that was liquid damaged around by the SMC U6100, and U7501 mostly. I have UC'd the board and replaced U7501 as well as some resistors that were damaged by the SMC. I am now getting 1.57v on PP5V_S5. I checked for PM_SLP_S4_L and it is showing 0v and not even a pulse when the...

Hi, This touchbar macbook originally had liquid damage only around the U3100 area. I had to run a couple wires on a resistor and capacitor due to the pads being gone on them. After that the machine turned on and everything worked fine. I sent it back to the customer and now they sent it back to...

I purchased this used board from ebay and everything else is functioning besides the sound. It is not recognizing any input/output devices and even when I plug in headphones nothing happens. I'm not sure where to measure on the logic board so I can see if this is something I can fix.

I got this 2017 13" FN keys macbook with liquid damage around the USB-C ports. I have cleaned and repaired and it boots up fine and everything works except for the keyboard. I don't know if I damaged the keyboard flex cable when I initially took apart the machine because it was kind of difficult...

This board had a small amount of liquid damage by the touchid/power button flex cable and the battery connector on the logic board was broken causing the machine to not charge. I replaced that power button flex cable and the J6951 battery connector. The machine was working perfectly fine a few...

This 15" A1707 board had the battery connector ripped off the board and the pads were all gone with it. I put another J6950 on the board and I had to run a wire from each pin to a nearby probe point. I did that and after plugging in the battery cable the battery said replace now and it wasn't...

This board was liquid damaged around the lcd connector area and the bottom side of the board by the lcd connector. I have replaced the lcd connector, lcd cable and the following components. L8300, C8300/03, C8359, I also replaced a component also in that area(image attached) but I don't know...

This board was sent to me a few weeks ago not turning on with liquid damage from UB400 down to the C9344 area. I replaced all of the damaged components in those areas except for UB400 and ultrasonic'd the board. It worked perfectly fine after that and it worked for a couple of weeks before the...

This 12" Macbook was sent in as intermittently turning on when the charger gets plugged in. I removed the USB-C charging port and noticed one of the pins were gone so I replaced the port and it turned on fine after that. The only issue was that the keyboard and trackpad were not working so I...

This 12" Macbook had liquid spilled on the keyboard by the customer. It had liquid damage to only 2 components that I could see. C7671/2 were both corroded so I replaced both of them. After plugging in the charger I keep getting a chime every few seconds and the machine keeps turning on and...

I have this new 2016 machine(non-touchbar version) that had no liquid damage at all but won't turn on at all. I haven't worked on these models but I did check out some of Louis' videos on this model. I am only getting around 5v on PP20V_USBC_XA_VBUS. I believe Louis said if you only get 5v you...

I have this liquid damaged machine. Initially the fan spun very fast and was making the 3 beeps Ram sound. I took the machine apart and noticed the underside of the fan was sticky and had liquid damage. After the board was ultrasonic'd the machine boots fine now but the fan issue remained. In...

This board had a small amount of liquid damage around the SMC area and in that area on the other side of the board I replaced several components around that area and have ultrasonic'd the board. Initially I started by replacing Q5030/50, R/C5329, C4901/20, R5488/89, C5489 C/U6901, C7782, U7780...

This board had liquid damage only on the bottom side of the board from the lp8550 across to U1950. I replaced the following components initially to see if I could get it working. U1950 + surrounding resistors/caps, Q8150 + resistors below it, C6100, U1900, C1910, C5010/17, C5002/07/08...

https://www.rossmanngroup.com/boards...ys-not-working This previous thread was marked as solved after I replaced the kbd connector because I thought that solved the issue. When I put the machine back together and booted the OS again that same row stopped working then after about 10 seconds it...

I have this board that doesn't show any signs of liquid damage. It shows a green light on the charger when plugged in but nothing else. PPBUS_G3H is 12.59v and there was no voltage on any of the S5 or S3 rails. I traced the issue to U7201 where there was 0v on PM_SLP_S4_L and SMC_PM_G2_EN. I...
