Sony LH70-3 DRO Repair Service

Professional diagnostic and board-level repair service for this Sony LH70-3 DRO.

Sony LH70‑3 is a 3‑axis digital readout (DRO) counter used on machine tools for precise position feedback. Common failures include loss of signal from the encoder interface, drift in display due to calibration file corruption, and power supply voltage instability causing intermittent resets. Check the 12 V DC input with a multimeter, verify that all cable connections to the encoder and controller are secure, and review any error codes or warning LEDs on the unit’s front panel before proceeding to firmware re‑flash if necessary.
