Sokki Electronics DU 203 F Display Unit

The Sokki Electronics DU 203 F is a precision digital readout (DRO) display unit used in laser sensors, displacement meters and vibration analyzers. Common failures on this model include LCD backlight degradation, internal capacitor leakage, and firmware corruption that causes the screen to go blank or display error codes; power‑supply voltage spikes can also damage the controller board. First‑check diagnostics: verify 12 V DC input voltage with a multimeter, inspect the LCD panel for physical cracks or loose connectors, and review any diagnostic LEDs or serial log output for error messages before proceeding to component testing.[oss-gpt-20b]
