Ticket 31551 - Use the known LED-lighting video and manual page when the symptom matches

• automation_draft_weakness: The automation stayed on a generic power-path diagnostic even though the reported Arcade2TV-XR symptom matched a known lighting issue that already has a concise support video and manual reference.
• manual_reply_improvement: Matt answered with a specific YouTube short plus the user-manual page reference, which gives the customer a faster, more concrete troubleshooting path than another open-ended wiring explanation.
• new_drafting_rule: When an Arcade2TV-XR customer says the lower LED panel shuts off shortly after startup and the symptom matches the known published fix, lead with the exact support video/manual reference instead of only generic power-path checks.
• confidence_effect: Raises future drafts from medium-confidence generic troubleshooting to a more directed, evidence-backed reply when the symptom pattern matches the known reference material.
• storage_decision: reviewable learning proposal

Why this matters

This is a concrete drafting-quality correction: the better next step was not to ask for broader isolation first, but to send the customer straight to the already available fix reference for this exact LED behavior.
