I have a LG TV. Purchased Apple TV... not enough HDMI connections on TV, purchased a splitter... connected everything, TV & Apple TV both worked for 3 days with no problems. Today I switched over to Apple TV & no signal... waited the 30 sections, still no signal. Tried moving connections, nothing.... help!
Splitters can be notorious for having compatibility issues, just to make sure try connecting direct to TV so you can see if the issue persists
What is your model Apple TV? Identify your Apple TV model - Apple Support
Is the status light glowing on the Apple TV? If your Apple TV doesn't turn on - Apple Support
Then that would confirm the issue is with the splitter and not the Apple TV itself. As I said those type of issues are normal with splitters, and they can come at any time.
If it has a manual then you can refer to that. Otherwise, you would have to reach out directly to the manufacturer.
I did connect Apple TV directly to my TV & it worked, but I did not want to continually hook it up or swap out for my Comcast cable... that is why I purchased the splitter.... it worked great for 3 days.... then ‘no signal’ today... nothing changed...
