If you like learning from me on YouTube, then sign up for Practical Board Repair School at iPad Rehab in upstate New York. I have been a teacher for over 20 years and our signature PBRS course is the culmination of everything I know about how to lead students on a path from noob to pro as fast as possible. The content is real-life open-ended examples, storytelling, and overlaying information to gradually build up a core understanding of how phones work and how they fail. There is absolutely no substitute for tons of time spent practicing under the microscope, but PBRS course is a great place to get your fundamentals—such as what does tigris do. [br]

The answer of course, is often “You Tell Me” So stare at the schematic, find tigris. Ask yourself “Is this mostly a data handling chip? Or is it mostly a power handling chip?” Look at all the clues that are on that page and answer this question. “If you had to make a $100 bet on what does this chip do, what would you say?” I bet you can figure it out.[br]
