Pattern to record: The display works from cold and turns off after a repeatable period.

Separate the panel from the source

Record resolution, refresh rate, colour mode and whether variable refresh is enabled. These determine link demand. Backlight and LCD edge-bond checks below apply only to LCD models, not to an OLED display. One possible explanation is that a component or blocked airflow reaches its protection temperature.

Display-path checks

1. Compare native and lower refresh rates, different certified cables and another graphics source.
2. Record temperature and operating time at controlled brightness.

Handling and electrical safety

Stop testing if the monitor emits a burning smell or flashes from its power section. Covering vents for testing can create further damage.

Image and input verification

If the checks support this cause, repair cooling, the heat-sensitive component or its supply stage. Verification should cover native refresh, lower refresh, variable refresh, colour, sleep and sustained gaming.

For an assessment of your gaming monitor, contact AEPC in Burswood or call 027 908 8880. Provide the model and the conditions that reproduce this problem. Workshop visits are by appointment.
