## Discrepancy

ON CLIMBOUT OF DFW AT 500 FT AGL, GOT LAV SMOKE WARNING ON EICAS.  FLIGHT ATTENDANT VERIFIED NO SMOKE OR ODOR.  EICAS MSG CLEARED AFTER 2 MINUTES.  CLEANED LAV SMOKE DETECTOR.  THE SAME PROBLEM OCCURRED THREE TIMES AGAIN OF IND ON 1/15, CMH ON 1/16, AND CMH ON 1/17.  THE LAV SMOKE DETECTOR AND PANEL WAS REPLACED.  THE FINAL FIX WAS REPLACEMENT OF NR 2 ENGINE DUE TO SUSPECTED CAUSE OF FALSE SMOKE WARNING.  NO FURTHER PROBLEMS REPORTED.
