Yes, and it happens a little more often than I'm comfortable with since anything over once is disturbing. Just out of the blue for no reason at all. Likes to kick into 3D mode once in a while too although not out of the blue but after switching back into standard mode after say watching HDR or a refresh rate change or similar and only from the video card output.
I won't rule out a video card driver causing the 3D mishap but I will for the display turning off and on for a couple seconds since the video card isn't being used when it happens watching cable and no others displays do this so it isn't the STB or cable feed imo. I can't rule out my Denon s720W either since it's always connected but does it in standby passing through.
The black screen happens on HDMI 1 input from my video card and on HDMI 2 input from my STB so it isn't confined to a single type of input or output nor to a specific port. HDMI 2 is not going through the AVR either which further helps eliminate it as the culprit.
So, in reality, I don't know who is to blame nor if it's just a bad mix of components? Furthermore, the panel just flashes to black a couple seconds. It isn't like the power supply turned off and on because I hear no internal switching and if it was a bad signal input from say the AVR, it doesn't remain black screen long enough to throw up the 'signal input missing' screensaver.
This was introduced 2 or 3 firmware updates ago and still exists. I'm on 1521 now still seeing it. No idea if an update was coincidence, the AVR is acting up, the STB is acting up, or panel is developing problems from age but I hope it's not the latter. It isn't growing more frequent and remains a rare nuisance.
