I have a Samsung 46 A750. I also have Time-Warner Cable with DVR service. I also have a Yamaha RX-V665 AVR.
I have One HDMI cable from the TV (mounted on wall) connected to my Yamaha AVR, and everything else is connected to the AVR, like the Cable, Sony BluRay, Another CD/DVD player that I use for playing MP3's and regular Audio CD's, a VCR is also connected to the AVR.
I contacted SAMSUNG because I have been getting blackouts on the TV with the sound still on that lasts for about 7 -10 seconds.
Samsung told me if I use the Samsung remote while it's in this BLACK MODE, and try the volume, tools, and menu on the remote,and you can work these features, then chances are it's NOT the TV, but maybe the Cable.
Does anyone else experience these temporary blackouts on their Samsung TV's? And if you fixed this problem, what were the reasons?
One thing I have not done yet, was to bypass the Yamaha AVR and connect from TV directly to the Cable box, but I wanted to see first, what else the problem could be.
