Hey i have the exact same problem When did this issue start for you? For me it started when i installed my hw-q800t soundbar. It especially happens when switching from hdmi to cable TV. Switching between hdmi sources goes fine most of the time. When it occurs i can hear the sound and only see an emblem of the source. I tend to fix it by shutting the tv off for 60 seconds. After that i turn in on and it does the same start up as if the power cable has been removed. After that it works most of the time for about 3-4 days. Hopefully anyone has any ideas or solutions?
