Diagnostic report for Strada meter LCD failure, displaying only half characters. Identifies causes and offers non-invasive solutions for retail environments.
This could indicate physical damage to the LCD or internal components.
This may point to a power supply or environmental problem.
This helps correlate the problem with any recent events or configurations.
LCD controllers utilize voltage to address individual pixels. A partial display failure suggests a problem in the controller's addressing logic, insufficient voltage reaching certain segments, or a failure in the LCD panel itself. Signal attenuation due to cable strain can also contribute. Electostatic discharge (ESD) during dry winter months can corrupt the display controller's memory. The display data uses a serial or parallel communication protocol and an issue with this could also result in corrupted display.
Static electricity can damage the device's electronics. Always ground yourself before handling the terminal. Cable strain is a major cause of failure. Ensure cables are properly secured and not bent at sharp angles. Safe Handling: Always unplug the device before any inspection or maintenance.
Regularly inspect and secure the LCD data cable to prevent strain.,Clean the LCD screen periodically with a manufacturer-approved cleaner.,Ensure the device is placed in a location with adequate ventilation to prevent overheating.,Implement ESD control measures, especially during dry months (e.g., anti-static mats).,Do not place heavy objects on top of the terminal.
Try pressing gently around the edges of the LCD screen to see if the missing characters reappear momentarily. If so, this could indicate a loose internal connection or pressure point issue within the LCD panel itself, warranting replacement by the manufacturer. If possible, compare the display output with another identical Strada terminal in the store to confirm the LCD failure.
