Liquid damaged Air board with most corrosion being around SMC area. Ultrasonic cleaned that up very well. After cleaning had no light on the charger and no fans so I went ahead and proceeded to fix the onewire circuit which had both the 10k and 4.7k resistor blown. Light is back again but now...

History of liquid damage. Cleaned and now we have a fan spin but no video. After a few seconds the fan speed starts to get a little faster. No beeps with RAM installed but also no beeps with RAM not installed. SMC and PRAM reset performed. Nothing replaced yet because I'm not sure where to start...

A little history for this one. It's a coworker of mine's computer and over the weekend he plugged in an external USB DVD drive which caused his machine for some reason to shut completely off. When he tried to power it back on, the LCD was completely shot with a blank display (worked on external...

As the title says, I have a 3435 Air board that has no power button functionality but all other keys work. Followed back from keyboard connector to the SMC Reset circuit and I'm assuming this is where the problem lies. This board was very lightly water damaged but has been cleaned and this is...

Trying to diagnose a rush repair 820-3332 board that was liquid damaged near the top edges of the board. After UC I do have a green light on the charger but no fan spin (SMC Reset is recognized). I have many missing power rails but I do have PP3V3S5_EN on U7201 with a full 3.3v. On other areas...

I've been staring at this board for a long time now and for whatever reason cannot narrow down what's causing PM_SLP_S4_L to not enable. Received board with no obvious water damage or corrosion anywhere, it actually looks spotless. I do have PPBUS_G3H and a green light on the charger and what I...

So I have a 820-3476 board I bought off of eBay with no backlight and its been kinda throwing me for a loop for a little while now. The backlight circuit looks slightly different than previous models with the 1st transistor (at the bottom of the first voltage divider) being integrated with the...

So I have a 17" Pro here that has minor water damage near the trackpad but doesnt appear to have gone near the board. I replaced the trackpad as well as the cable twice and the trackpad is registering a click just fine but the cursor doesnt move. I have tried external bootables and verified the...

So I have a Macbook Air here that was mildly water damaged, ran it through the cleaner and everything worked, even booted up except the trackpad. So I replaced the trackpad as well as the trackpad cable and now it won't power on without shorting the power pads on the back of the board. Once that...

So this project has been a little disasterous for me so far.. Was a routine Macbook Air LCD-only replacement (done plenty before) but after installation of a new LCD the backlight appeared to be out (could see apple logo on the LCD). I replaced the backlight strip because i had some scratches on...

So on this wine damaged board... I have pp3v3_s5 and pp5v0_s5 rails but PM_SLP_S5_L is missing on u8170 causing it to be unable to enter into S4 state. PP3v42 is present and I have charger light. I narrowed it down to something near U1950 I believe which has 3.42v on pin 8 and 0.19v on pin 2...

Kinda stumped on where to go with this one.. Missing PP5V_S5 and the SMC area is getting really warm (and is shorted), however I do indeed have pp3v42_g3h and a green light on the charger. I have gone back to the S5 enables and found 1.2v on pin 6 of u7941 (supposed to be PP3v3_s5)... I've also...

So this board was liquid damaged although I saw no signs of liquid damage on the board itself, i cleaned it anyways. The machine boots up and chimes just fine, has all main power rails ect. The only issue is the board isn't recognizing any keyboard input from the internal keyboard. I have tried...
