Hantarex Polo 25" monior chassis

The Hantarex Polo 25" monitor chassis is an Italian‑made arcade CRT display used in mid‑90s cabinets (e.g., Midway, Capcom). Common failures include arcing or failure of the flyback transformer (often the HR7191/TH103), exploding electrolytic capacitors on the power supply and picture‑location potentiometer mis‑adjustments. Typical symptoms are a dead screen, flicker, or incorrect image placement. First‑check diagnostics: verify mains input voltage and output rails, inspect the flyback for arcing and replace if needed, test all electrolytics for leakage/rupture, and adjust the picture‑location pot to correct image geometry.[oss-gpt-20b]
