Diagnosing Audrey terminal partial image post-power surge: Possible causes, non-invasive solutions, and ESD/cable strain prevention for retail environments.
Check grounding of the surge protector. Improper grounding renders it ineffective.
A damaged screen protector can distort the image. Remove and inspect.
Connected peripherals could have contributed to the surge damage.
LCD/TFT displays on payment terminals require stable voltage and data signals. Power surges can damage the display controller, backlight inverter, or the LCD panel itself. Signal attenuation due to cable damage can also lead to partial image display. ESD events, especially in dry environments, can corrupt display controller firmware.
Terminal displays a partial image. Initial report indicates occurrence following a power surge. Physical screen damage also reported.
Install a surge protector to protect the terminal from future power surges.,Ensure proper cable management to prevent strain on the display cable.,Use a humidifier in dry environments to minimize ESD risk, especially during winter.,Regularly clean the touchscreen with a screen-safe cleaner to remove dirt and grease.,Train staff on proper handling procedures to avoid physical damage to the screen.
Try applying gentle pressure to different areas of the screen while the terminal is powered on. This may temporarily restore the image if there is a loose connection within the LCD panel itself. Document results. Note: This is diagnostic only, not a permanent fix.
