Well did you try the function key on your laptop? Since the video jack and the audio jacks are separate on the computer to the TV, that is why you hear things but don't see anything - the video can be shut off using the Fn and the CRT/LCD buttons on your keyboard. In most cases, this accidently get tripped while typing away, since the Fn key is so close to the space bar, and in most cases, the CRT/LCD key is somewhere near the &/7 key.
With the computer ON and hooked up to the television -
1 - HOLD the Fn key down (it acts as a manual SHIFT key, so to operate its functions, it must be held down)
2 - Press the CRT/LCD key (If you don't have a key marked this way, look for one that has the images of 2 screens on it - one showing a blank frame, and the other a solid 'lit' frame). This is a multiple action switch, so you may have to press it multiple times. The actions should be -
- FIRST PRESS - Switches ON the external jack sending an image to the TV, while also leaving the computer's monitor on as well.
- SECOND PRESS - Feed to the TV on the external jack should continue, but now the computer's monitor is shut off (It can sometimes be distracting to have two monitors showing the same image side-by-side).
- THIRD PRESS - Turns computer's monitor back on, and shuts off feed to the TV.
Mind you, this order is not the same with all laptops, and in most resent models, the CRT/LCD key does not do anything if the computer doesn't 'see' anything attached to the external jack.
