Bubba-Gump 0 Posted May 23, 2019 I have a tmezon MZ-HD1416m. When I first installed it the V-Out (RCA video out) worked fine. I did an online firmware update via the info menu, and now I only get the tmezon logo on the display monitor. Does anyone know the default firmware version for this DVR so I can downgrade the firmware? current version is: v4.02.r11.00000140 Thanks. Share this post Link to post Share on other sites
