In this repair , the board would not power on. During the course of our troubleshooting, we narrowed down the issue to the NAND circuitry , we narrowed down the failed components and made replacements, but that didn’t fix the issue right away , ad the device will only start with trackpad feedback but no POST , we then tried to revive the device , but was failing with error 6, so we again took out the board and then realised that the 2.5V line for the SSD we addressed was still shorted through the capacitor we replaced , and in our negligence, we didn’t confirm the voltage on the line or check for a short before installing the board in the shell, this was addressed and resolved the second time.

@@generalislive7 can you maybe tap on the caps lock key to see if the LED comes on? If not, you can press and hold the power button to forcefully shot down the Mac and then power connect your charger to see the response, just by the way, I supposed you are using a 96 charger

Nice repair and pretty good practical skills considering your equipment. You definitely deserve a better soldering iron for 0201 components and at least a microscope for better content quality. You also sounds really funny and that pushed me to subscribe to your channel. Keep on rocking man! Wish you the best.

@@resetlab7142 I'm digging in what I thought could have been a similar problem and just find out has nothing to do with it. I hope to solve it with a DFU. Keep in touch. Where are you based in S.A.? I have a good Italian friend living in Capetown.

@@UshasreeKondapi hello there , thank you for taking your time through the video, to your question, you have to look into a practical and cheaper way to acquire donor boards , for me , you can start by buying dead machines,

Hello, my friend, Do you have the troubleshooting tools,? Screw Drivers, Multimeter. Do you have feedback on your trackpad? did you notice the battery percentage before you closed the lid? Please let me know.

Thanks for replying. I don't have any of those tools, sorry. I am an end user. The battery percentage was around 70%, and how to check the feedback on the trackpad?
