Who I am

I'm Joe — a board-level electronics repair technician specialising in logic board diagnostics for Apple MacBooks, GPUs, and gaming consoles. I work at the component level: tracing voltage rail faults, reading schematics and boardviews, identifying failed ICs, and performing SMD rework including BGA reballing.

I built boardrepair.me as the reference I wished existed when I started. Every voltage table, diode mode reading, and power sequence on this site comes from direct bench work — real measurements on real boards, not scraped documentation. The diagnostic tools are built around the actual fault patterns I've observed across hundreds of boards.

The site is free and requires no account. My goal is to make level-3 repair data accessible to independent technicians who shouldn't have to reverse-engineer every board from scratch.

What I work on

MacBook logic boards (Intel + Apple Silicon) 820-xxxxx series board diagnostics GPU card board repair (NVIDIA, AMD) PS4 / PS5 / Nintendo Switch Voltage rail analysis (PPBUS_G3H, S5/S4/S0) ISL6259, CD3215, TPS51125 diagnosis BGA reballing and reflow Schematic and boardview reading DC injection and thermal imaging Short circuit isolation

What's on this site

boardrepair.me covers: level-3 diagnostic guides for specific board numbers, voltage rail tables with per-rail test points, diode mode reference readings, schematics and boardview availability index, a component library with replacement cross-references, and a symptom index linking symptoms to likely fault trees.

The blog covers specific repair methods, component theory, and tool techniques that are immediately applicable at the bench — no filler, no sponsored content.

Get in touch

I read everything. Corrections to guide data, schematics or boardviews to contribute, or technical questions about a specific board are all welcome.
