I'm having a peculiar problem with my MU8000 by which it turns itself back on a few minutes after I've used my Fios remote to simultaneously turn off the STB, my Marantz AVR through which all sources run, and the TV, itself. I never had this problem before I upgraded my TV and AVR, but I suspect it has something to do with the HDMI-CEC settings in at least one of those components. By way of further background, after the TV turns itself back on, the screen saver or sleep mode of the FIOS service appears on screen asking me to either turn off the monitor or press "Menu" on the Fios remote to resume service. This is how the FIOS STB normally operates.
Any advice? Again, I suspect it's not a defect in the Samsung, rather something to do with HDMI-CEC, but I don't want to disable any other capabilities. Thanks!
