Lunar Corp 7635 Circuit Board
 |
The Lunar LNR7635 is the main CSBC (Control System Board) used in GE/Lunar Prodigy bone densitometers, handling signal conditioning, power regulation and communication with the patient interface. Common failure modes include degraded electrolytic capacitors on the high‑voltage rail, burnt or cracked MOSFETs on the 12 V regulator, and firmware corruption that causes the board to hang during startup. First‑check diagnostics: verify all input voltages (24 VAC, 12 VDC) with a multimeter; inspect for bulging or leaking capacitors and test the power‑regulation ICs with an oscilloscope; review any error codes displayed on the patient monitor for clues to communication faults.[oss-gpt-20b] |
