I am trying to troubleshoot my early 2011 MC723LL/A Won’t switch on, won’t charge and shows no led on charger. Replaced battery and charger but no change. I have removed logic board and photographed. I have no clue what to check or look for so any advice is appreciated. I can add any images needed What should I be looking for and testing? Thank you!

As you can imagine, going from having no clue to being able to troubleshoot a logic board takes years time and/or an engineering degree. Here you’ll find plenty of people willing to help if a modular approach is possible (replace this or that) but that’s not what you need here. Unless you’re willing to dive into schematics and start probing yourself, the issue your Mac seems to have needs a logic board replacement or a component level repair.
