Sony LH30-2 DRO
 |
Sony LH30‑2 is a two‑axis digital readout (DRO) display used on CNC machines and precision tooling. Common failures include loss of power to the display panel, erratic or no scale readings due to damaged analog‑to‑digital conversion circuitry, and intermittent backlight operation caused by failing LED drivers. Check the 100/120 VAC input for proper voltage and continuity; verify that the internal LCD controller board shows correct I²C/SPI communication with the host controller; inspect the display panel connectors and solder joints for corrosion or broken traces. If the unit powers on but displays no data, test the analog signal inputs and replace any failed op‑amps or ADC chips as needed.[oss-gpt-20b] |
