GE-Lunar 40242 Power Supply Repair Service

Professional diagnostic and board-level repair service for this GE-Lunar 40242 Power Supply.

GE‑Lunar 40242 PIB Box Assembly is the photomultiplier interface module used in Lunar DPX/Bravo bone densitometers to convert X‑ray signals into electrical outputs for image processing. Common failure points include degraded PMT gain due to aging photocathodes, loose or corroded connector pins on the interface board, and power supply ripple or voltage drop across the 12 V/5 V rails that can trigger error codes such as “PIB‑FAIL” or “PMT‑OVER”. First‑check diagnostics should verify the supplied voltages with a multimeter, inspect all cable connections for continuity and physical damage, and review the system log for recent error messages before proceeding to replace or re‑calibrate the PMT board.
