No idea if anyone will have any idea here with MacBook board level repairs. I have a 830-00165 Board that was liquid damaged. I was able to find a short under the CPU last week and got it working. Then it stopped working again after I assembled it. I got to the point where I have replaced the resistor on PPBUS_G3H_R which is R7006. I’m still not getting any image on the screen. Any help would be great.
If the MacBook is not lighting a USB mouse after 1 minute of initiating boot and the CPU is cold, it is not posting. If it is lighting this, the issue is no image. Find out what problem it has, then we can advise. No image and no chime are completely different issues and need to be investigated differently. If it is not passing POST, check out the CPU power rail and SPI ROM area. With board level repairs, it is very difficult to advise with the more complex issues over the Internet without looking at it; thoroughly check over the board using a microscope to see if there is any minor liquid damage or corroded traces
