Bench guides

The bench, in writing.

Component-level guides to the failures we actually see, across the brands we know. Grounded in real repair patterns and bench work, not forum rumors.

What we actually see on the bench.

Each guide starts from real repair patterns across hundreds of brands. No parts-swapping shortcuts, no invented prices. If a fix needs a bench, we say so.
