The Monitor 265 is a 26.5‑inch high‑resolution display, typically used in industrial or professional workstations where precise color accuracy and fast response are required. Common failure modes for this class of monitors include backlight LED degradation (leading to dimming or uneven illumination), power supply board faults causing intermittent startup or complete blackouts, and capacitive discharge issues on the main PCB that can trigger random resets or flicker. Additionally, high‑frequency refresh rates may stress the GPU interface, so a failing HDMI/DisplayPort connector or cable can produce signal loss or artifacting.

First‑check diagnostics: verify mains voltage and the monitor’s internal power supply output with a multimeter; inspect all connectors for corrosion or loose pins; perform a visual inspection of the PCB for burnt components or swollen electrolytic capacitors. If available, review any diagnostic LEDs or error codes displayed on the unit before proceeding to component replacement.[oss-gpt-20b]
