Show the arithmetic for both scores
Each score = 40% cost + 40% success + 20% difficulty. The DIY score is also capped on hard jobs (4/5 max 74, 5/5 max 60). Replacement price $249.99. Success points 55 (Mixed) for both paths: The cause isn't obvious: main board, power board, firmware or a backlight short can all look like a boot loop. Evidence for this exact model is thin (one forum thread and LG's generic guide). How is this scored?
DIY score 68 (coin flip): repair cost $49.88 (parts price, average of range) ÷ $249.99 = 0.200 → cost points 84.7. Difficulty points 60 (Moderate (3/5)).
0.40 × 84.7 + 0.40 × 55 + 0.20 × 60 = 67.9 → 68
Shop score: no score. No verified price yet, so RepairOdds shows "No price yet" rather than guess.
Board swaps are easy; diagnosis is the hard part. Replacement price is the cheapest comparable listing found: New LG 55-inch NU70 Nano 4K (2026).
