I have recently purchased a Lg 70 uh6350 and hooked it up to my Onyko 626. Everything is connected the same way as my older Samsung was. All devices att cable box,xbox,rasberry pi,etc all connected via HDMI in onyko. The HDMI out is going to the TV. The lg works fine for the cable box but does not show a picture for any other onyko input. I have switched which input on the lg km using but still no luck im out of ideas? Any suggestions??
