I just got the 1800e 4 days ago, so far I also have had a black screen issue (had to unplug the unit), another time the screen was dim for 30 seconds, then was ok. And another time it was black for 20 seconds, then flickered for 10 seconds, then was ok. Other times its starts up fine, and works great once its on. Other than netflix is choppy and audio/video out of sync. It came with the latest firmware. Hooked up to a Sharp Aquos 46le810un with hdmi, and hardwired network. Is downgrading the firmware an option or not recommended??
