Hundreds of Los Angeles County centers opened for early voting Saturday ahead of next month’s presidential primary election, giving voters a first glimpse of the $300-million overhaul of the county’s balloting system.

Some hiccups were reported.

About a quarter of the county’s 960 voting centers were slated to be open from 8 a.m. to 5 p.m. starting Saturday. But some of them were unable to open on time because supplies or equipment needed to be set up had not yet arrived, said Michael Sanchez, deputy communications director for the county registrar’s office. At other centers, workers did not have the security codes or login information necessary to start the new touch-screen ballot-marking devices. And some places were dark even though they appeared on the county’s official list of early voting centers.

The registrar’s office was still determining how many locations were affected by the problems but confirmed that at least 10 voting centers in Hollywood, West Hollywood, Silver Lake, Eagle Rock, Montecito Heights, Lincoln Heights, downtown L.A. and Pomona either opened late or not at all.
