hantarex polo2/14 63202671 monitor

Hantarex Polo2/14 63202671 is a 15‑inch CRT monitor with an internal switching‑regulator power supply and an HR7191 flyback transformer. Common failures include blown or degraded electrolytic capacitors in the regulator, a defective flyback transformer (especially after power surges), and filter capacitor issues that produce vertical banding across the image. First‑check diagnostics: verify 12 V/5 V rail outputs from the regulator, inspect the flyback winding for continuity and insulation resistance, and visually examine all capacitors for bulging or leakage; then review any error codes displayed on the monitor’s diagnostic panel.[oss-gpt-20b]
