Hi all. Been searching and kinda stumped. I bought an HDMI switcher and used it to connect a Wii U and Apple TV to one of the HDMI ports. Occasionally the TV has issues turning off or accessing the input menu and I'll see the power LED flash green. Last night, when I switched on the Apple TV and sound bar, the screen kept switching between empty black with no sound and very briefly the image from the Apple TV. I wasn't able to use the TV remote to change inputs or do anything. My other HDMI ports, the PS3 did the same thing, the Xbox 360 worked fine. I had to physically unplug and the TV from the wall and then plug it back in and fire it all back up. Then everything was fine.
Curious to see if anyone else has had this issue and what it may be, and if I have a time bomb on my hand. Thanks.
