Film a repair decision tree, including when to stop

Plan a short video about diagnosing [SYMPTOM] on [ITEM]. Use only the user-provided manual and observations [EVIDENCE]. Open with a safety check and a clear stop-and-contact-a-professional branch; then storyboard visible low-risk checks in order. For each branch give shot, on-screen question, likely observation and next action, never an unsupported diagnosis. Include captions and a closing decision card. Do not show bypassing guards, opening live electrical equipment or hiding uncertainty. Check that every depicted operation is justified by supplied evidence and can be performed safely by the intended audience.
