Per component researched, use this table:
| Component | Marking | Identified As | Package Match | Datasheet Source | Confidence |
|---|---|---|---|---|---|
| U1 | TP4056 | Li-Ion charge IC (TPOWER/TOPPOWER) | SOT-23-8 ✓ | lcsc.com / datasheet PDF | Confirmed |
| Q1 | S8050 | NPN BJT 25V/500mA (SANYO) | SOT-23 ✓ | datasheet PDF | Confirmed |
| IC2 | "A3C" | Unresolved — 3 candidates found | SOT-23-5 | — | Unclear |
Classification for each component:
- Confirmed — full datasheet match: marking, package, and pinout all consistent
- Probable — typical application match, no exact datasheet found for this specific marking
- Unclear — marking unresolvable or multiple conflicting candidates — state this explicitly
07_diagnosis_update.md
Updated hypothesis status after research and measurements:
| Hypothesis | Status | Evidence Basis | Updated Confidence |
|---|---|---|---|
| H1: Cold solder at J1 | Confirmed | Measurement 1: 0.4V drop under load [Messung] | 90% |
| H2: Degraded battery | Refuted | Cell voltage drop only 0.05V under load [Messung] | — |
| H3: SW1 contact fault | Still Open | Not yet measured | — |
final_report.md
Structure:
- Executive Summary (2–3 sentences: device description, reported fault, top probable cause)
- Evidence Base (key observations, measurements, and research findings that form the diagnosis — each with source tag)
- Most Probable Root Cause (with confidence %, e.g., "Cold solder joint at J1 pin 1 — 85% confidence")
- Recommended Action (specific, actionable repair step, e.g., "Reflow solder joint at J1 pin 1 with fresh flux; test under load afterward")
- Alternative Causes Still Open (secondary hypotheses not yet ruled out)
- Limitations (what could not be determined without additional measurements or equipment)
