Hesston 700719139 is an industrial display unit used to monitor and present critical process data in heavy‑equipment or agricultural machinery. Common failures include power supply dropout, backlight or LCD panel degradation, and loss of communication with the control box due to damaged wiring or connector corrosion. The display may also exhibit erratic screen flashes or static if its internal controller board has burned out or suffered a short circuit. First‑check diagnostics: verify 12 V/24 V supply voltage at the display terminals; inspect all I/O connectors and cable harnesses for signs of wear or corrosion; and review any diagnostic LEDs or error codes on the unit’s front panel before proceeding to internal board testing.[oss-gpt-20b]
