When I turn on the Xbox all I get on my TV is a black screen with green lines

It sounds like it’s not getting good connection or that either the wire or possibly the hdmi output could be bad on the xbox. Try hooking it up with a different hdmi cable first, also if your tv has different hdmi inputs try using a different one…or try using a different tv.

my Xbox 360 e well turn on but wont show up on my TV i tryed 3 HDMI cables and 4 av jacks but still nothing do you have any ideas.
