Source Input
how to hook a xbox360 console to a dynex tv?
When choosing source input it says no signal
“No signal” means exactly that–the TV cannot see an incoming signal on whatever input you’ve selected. You need to ensure that the Xbox is functioning properly, is sending a game to the TV, and is connected properly (cables seated firmly on both ends, etc.).
Then you need to ensure that you’ve selected the correct input. A “no signal” message is automatic if you haven’t switched the TV to the proper input.
