Cannot find any liquid damage, it chimes, caps lock working, nothing on screen (not even blink of image), nothing on external with known good SSD. Just once I've seen a short blink of white screen (with backlight) during chime - that's why I did not trash this board yet. When it came to me...

It turns on and chimes, has good CPU Vcore, but no PPVCORE_GPU (and it's not shorted to GND). Someone obviously messed with U9300, Q9330, Q9331 and Q9361 as U9300 has no bond on the edges and all of these had flux residues around. I changed all of them, but it's still the same. GPUVCORE_EN and...

Hello, I've got an issue with 820-00928 (15" 2017), it came to me dead. Board has no corrosion, but someone obviously reflowed or maybe replaced U7000 and CB704 - I guess that's because Louis did this in one of his videos (it's funny how often I'm getting boards from other repair shops where...

This one came to me not powering on at all. There was no obvious liquid damage, but I found burned U8030 and no PP3V3_S0. So I changed U8030 and the board powered on with chime. After that I installed the board back to case and once I connected the charger to an assembled laptop, U8030 burned...

I cannot figure out this one and I've got a feeling that this is just some stupid mistake I'm doing over and over again :D No liquid damage, oxidation, signs of previous repairs or any other damage anywhere in this laptop, system board looks almost like a new one. Customer says it just did not...

I've got here a board that cannot boot. It turns on, shows the Apple (with loaded SSD), but then it freezes a moment before it should display the login screen. Sometimes the Apple has slight red lines on that moment. Then it restarts and do it again in a loop. I believe it's the moment when it...

820-3330 from A1286 2012 There is no picture (even on external screen) and no chime, but CPU and GPU warms up. It beeps without RAM, but that's the only sign of life. Will not start in SMC bypass mode, or after SMC reset - I've never seen it running. I tried to flash the BIOS chip with known...

820-00045 (A1534 e2015) The machine looks like a new one, not even scratched, 17 cycles on battery, no signs of spill or previous repairs anywhere, board is spotless. It was dead when it came to me, no response on anything. Initially it had 8.6V on PPBUS_G3H and S3/S0 rails were pulsing from 0V...

Hello, I've got here 820-3787 that turns on to a questionmark folder with known good drives (with High Sierra installed and running on different machine). It will also not find any wifi network in boot selection menu. USB is fully functional. I bought this machine with no video issue, but...
