top won't go down on 1992 Mercedes-Benz 300SL

brought car in for new starter, startre replaced. mech had top down for final inspection, put top up, now nothing. all the obvious gone through. still perplexed.

Asked by for the 1992 Mercedes-Benz 300SL
this convertible top has an electric hydraulic pump. when
the fluid gets low, it will not work. you probably have one (or more) cylinders that are leaking. you will need a
Mercedes specialty shop to diagnose this problem. and have you wallet ready, those cylinders are pricey.
