I have my 656 hooked up to my LG oled via HDMI2, using arc.
Over the time i`ve had it, occasionally the LG will show "No Signal Detected" "Please Check Connections". I just change inputs and back to what i want to watch and everything is fine.....until last night. It happened again, but nothing happens when i try and change inputs.
No visuals, but i have audio. I can hear Sky Tv. I hear X box/Playstation turn on etc. When i plug those consoles straight into the Tv, all work fine, so i know they and the HDMI cables aren't the problem. I have used 3 different HDMI`s from HDMI Out Main (Arc), to the TV HDMI IN, 2 (Arc), and none work, (apart from audio).
Nothing has changed, no settings touched.
When i go to the LG settings-All Inputs-HDMI2, the preview box in the centre is black with "No Signal"and underneath, the Connected Device Info is empty, with "No Information", where it used to say "Onkyo AV Receiver Connected".
I decided to see if there was a system update available, using the menu on the Receiver, and there was. I updated it, and the LG preview box realized and showed it was connected to the Receiver, (getting my hopes up), but after the update, it disappeared and i still have no picture.
So...has anyone any info on this, is it a big issue, can it be repaired cheaply, (its not even 2 years old), have i any chance of Onkyo fixing it for free??
