Ball Electronic TV‑70 is a 7‑inch CRT display monitor used in industrial control panels and HMI systems. Common failure modes for this class of units include power supply board faults (over‑voltage on the 12 V/5 V rails), capacitive degradation on the main board, and backlight driver failures that cause dim or flickering images. First‑check diagnostics: verify AC input voltage and monitor output to the panel; inspect the power supply PCB for burnt components or swollen electrolytics; check the CRT high‑voltage transformer and backlight ballast for continuity and correct operation.[oss-gpt-20b] |
