Narrative:
Going into lax on paradise 4 arrival landing runway 25L, approach changed runway to runway 24R. When updating FMC, tejay restr dropped out and plane continued to descend for mitts intersection at 10000 ft. After taking manual control, flight continued uneventfully. Total deviation was approximately 300 ft low 2 NM south of tejay. Crew coordination prevented this from being worse and better coordination would have prevented it altogether but lax is the worst for multiple arrival and runway changes. Something needs to be done to limit these excessive changes during a critical phase of flight!

Title: B757 FLYING FO MISSED STAR XING RESTR GOING INTO LAX DUE STAR ASSIGNMENT CHANGE HAD AUTOMATICALLY DROPPED THEIR NEXT STAR FIX FROM BEFORE THEIR RTE CHANGE.
Narrative: GOING INTO LAX ON PARADISE 4 ARR LNDG RWY 25L, APCH CHANGED RWY TO RWY 24R. WHEN UPDATING FMC, TEJAY RESTR DROPPED OUT AND PLANE CONTINUED TO DSND FOR MITTS INTXN AT 10000 FT. AFTER TAKING MANUAL CTL, FLT CONTINUED UNEVENTFULLY. TOTAL DEV WAS APPROX 300 FT LOW 2 NM S OF TEJAY. CREW COORD PREVENTED THIS FROM BEING WORSE AND BETTER COORD WOULD HAVE PREVENTED IT ALTOGETHER BUT LAX IS THE WORST FOR MULTIPLE ARR AND RWY CHANGES. SOMETHING NEEDS TO BE DONE TO LIMIT THESE EXCESSIVE CHANGES DURING A CRITICAL PHASE OF FLT!
