Here is a 820-00164-02 from a customer: https://youtu.be/lKsauXvYJDQ He didn't know he had such thing in his Mac. He was supposed to have a 820-3435 board (2013 MacBook Air 11") Must have been replaced by a shop while he got his screen replaced... though why?!... hahaha

Hi, I have that MacPro which just light the I/O board for a few seconds and then turns off. I can't even say it tries to turn on. After disassembling the unit, I've found some corrosion on the interconnection board. I have reworked that board as thorougly as I could but no improvements. I am...

Hi, a little bit bit off topic... Can someone tell me if a replacement is possible or is there a lock (like with the Wi-Fi card)? I know the drives are swappeable on this model but will the system recognize the new drive inserted or not? if not, anything we could do to bypass that? About to...

Hi, I have that board which had a small liquid damage near SMC (L5001), Bios (the prob points on the right of the Bios, opposite clock chip) and Thunderbolt circuitry (U3210) I've cleaned the area, replaced the Thunderbolt chip and L5001 but wouldn't start. I did then replace the SMC with one...

Hi, Simple question... if we need to replace a CD3215C00 from any board model, can you use another board model chip or are the chips programmed for a specific model? Thanks!

Hello, I have that 820-3476 which looks perfect, absolutely clean, pulsing but would not start. I was planning to give it a clean using the ultrasonic cleaner but before that I thought, let's check with another Bios. I did try a Bios I've found on vinafix and it did start but bad ME region...

Hi guys, Following last Louis/Duke video, I am wondering how complex that process of flashing a PC card with the Mac Bios card is? Has anyone tried yet? From what I understand you simply need to add the EFI part that the PC Bios is missing. Buy a similar model card for a PC laptop and flash...

Hi, I have that board which apparently had a tiny little liquid damage around U5580, R7237 and Q7321 (GND side). -U5580 had a corroded pin 3 which was fixed and chip was replaced. - R7237 wasn't replaced at it does measure fine. I have just re-applied some solder on each side of it. - Q7321...

Hi, I have that board with an important liquid damage near U9701 and a slight one near U7201. The board has quarter fan spin. When the charger is plugged, PPBUS_G3H will come and then drop. I've checked the current sensing resistors which measure fine. I did reflow both areas and replaced...

Hi, We have that MacBook Pro 13" 2012 which came in as the customer was complaining about a slow Mac. As usual on these machines, I did blame first the SATA cable but it was fine. Drive did test fine too... Opening the case we could clearly see a blown capacitor (C6603) Voltage drop to ground...

The customer brought us her MacBook Pro 13" Touchbar from 2016, not turning on. She said the computer was working fine yesterday when suddenly it did shutdown. History of that computer: Mainboard (HD says the customer) was replaced. She lost all her data. So I assume mainboard was replaced...

Hello, We have that MacBook A1534 board from 2015 which shows no picture on the screen sometimes. We have tried on both the customer screen and our known working screen but the same thing is happening. PPVCC_S0_CPU is 1.7V and board is getting hot. EDP_PANEL_PWR is a flat 0V (unless screen...

Hello, We have received that MacBook retina 12" 2015 for servicing with a broken charging port. Charging port will work but not lock the charging cable. Other than that, Mac was working fine. After pulling out the computer and replacing the USB-C cable, we can't get it to boot up with a new...

Hello, Simple question... is the SMC swappable between a 820-3662 board and a 820-3787 board? Thanks

Hello, I have that mainboard which had Q7802 ripped off and which has been obvisouly reworked near the jack connector. The board would not start until I re-install Q7802. Now the board has the fan spinning but doesn't seem to get a hot enough CPU and has no picture either on the LCD or the...

Hi, I have that board was not turning on at first + no green light. Replaced DC-IN board as some diode mode very different from a known working one. Still no go. I saw a difference in diode mode on F7005 between each side of it. Replaced F7005. Got a quick green light on the charger then off...

Hello, We have that board which won't detect a camera. We have tried a known good display and same result. I did test in diode mode the camera connector with the camera plugged and not plugged and compared it with a known working board. Here are the results: 0 0 0 0...

Hello, I have that 820-00165 which won't start however it is getting 2 pulses of the CPU_Vcore and ALL_sys_pwrgd. Liquid damaged near the Bios and U7600. I have reflowed the area and replaced the dirty looking resistors. U7600 was also replaced. I have followed the SPI traces and everything...

Do we have any news regarding how to read/program an SMC? I remember when I was using my old hackintosh back in 2007 (I think) we had that guy Netkas who was a Guru and was able to simulate an SMC. I bet he did some reverse engineering to achieve that. Now, since it has been a long time, no...

Hello, That board was messed up by an Indian shop which I will keep the name secret. The issue is it has graphical glitches when you are not moving the mouse, and that only when using the integrated GPU, Iris. Please check the video I've made : https://youtu.be/OOYrZO6wDvA Board has been...
