ESA TRIA 4000 display unit

ESA TRIA 4000 is an industrial computer/control system featuring a 10‑inch monochrome CRT display and internal storage on one or two disk drives. Common failure modes in this class of equipment include power supply degradation, CRT backlight burnout, static RAM corruption, and mechanical wear of the drive heads or cooling fans. Begin diagnostics by verifying that the unit receives proper 120 V/240 V input and that the regulator outputs match spec; check the display for flicker or ghosting and inspect the CRT for bulging or cracked glass; finally, review any logged error codes on the controller’s panel to isolate memory or drive faults.[oss-gpt-20b]
