The STAR (Stadium) final scope lost all data tags and radar. Initially; the scope froze; then the tags dimmed; and finally the scope went black. This was during a busy Los Angeles arrival push. The controller leaned over and used the DNYR (Downey) scope next to him to provide services. STARS was installed a very short time ago.  We have seen an increase in software issues related to software updates 'STARS drops.'  A few weeks ago the STARS system was deemed unreliable and the traffic rate was drastically reduced. Many delays incurred. The controllers/FLMs [Front Line Managers] do not have confidence that the equipment is capable of delivering a consistent product. This was a total loss of data.
SCT ATC Front Line Manager reported losing all data tags on the Stadium Radar scope. The Front Line Manager reported the confidence level in the equipment is low due to a decrease in reliability.
