Electronic Circuit Troubleshooting
Move beyond basic multimeter readings to systematically diagnose and repair complex hardware failures. Learn to isolate faults, interpret signal noise, and reverse engineer circuits without a map.
Like Duolingo, but for Electronic Circuit Troubleshooting. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A deep dive: 34 levels across 5 sections, about 68 minutes end to end, roughly 14 days at five minutes a day. It moves through The Diagnostic Mindset, Component-Level Forensics, Advanced Signal Diagnosis, Real-World Challenges, and The Physics of Failure. It assumes you already know the basics.

Key ideas in Electronic Circuit Troubleshooting
- Functional blocks process signals in a linear chain
- Probing the preamp output isolates the fault
- Half-Split method starts at the middle
- Half-Split downstream movement
- Binary search pattern efficiency
- Applying functional block isolation to a dead device
- Executing the Half-Split method on a long signal chain
- Known Good points are reliable nodes used to verify that specific subsystems are operational.
- Comparing a faulty board to a working 'golden' board helps identify abnormal voltage levels.
- A 'source' problem exists in the stage providing power, while a 'load' problem is a downstream short.
- Identifying Known Good baselines for comparison
- Disconnecting the load and re-testing the source reveals if the downstream circuit is pulling the voltage down.
- Thermal runaway sensory cues
- Electrolytic capacitor failure signs
- Distinguishing between source and load problems
- Discolored PCB traces
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Electronic Circuit Troubleshooting the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
Here's what playing it feels like
A real question from this course. Take your best guess.
If an amplifier is powered on but silent, where should you probe to quickly determine if the fault is in the control stage or the power stage?
