I’ve read dozens of threads about the “no signal” problem when the Arc is connected via eArc but still have an issue that appeared recently.
No config change, but I did receive a new TV box from my provider. Since, then, when turning on the TV, I get a “no signal” message on the LG TV.
Apple TV works fine constantly. Switching the input back to TV gives “no signal” again.
I performed the TV setup after unplugging everything and letting the TV etc unplugged for about 10 mins.
I performed a factory reset on the Apple TV, Arc, LG TV, and received a new TV box from my provider as they thought it was the culprit.
If I plug the TV box directly in the TV HDMI port (not via eArc), it all works fine.
But via eARC, the Apple TV will always work and the TV box will pretty much always show “no signal”, black screen and of course no sound.
If I un/replug the HDMI of the TV box, sometimes, the Arc LED turns green, sound starts playing and the image appears again. Sometimes the sound will start playing but without any image (“no signal” disappeared though). Sometimes, no change at all, still “no signal”.
I feel like I wasted so much time trying so many things… why is the Arc so annoying now? It works flawlessly if I bypass the Arc… but that’s not really the point.
Thanks
