If I try to take a photo of the TV with a camera (when the TV is on) there are often thick black lines over the screen. Basically, anyone know why??!! Also, does anyone know how you can stop this from happening.

its because of the way your TV displays a picture
it is actually lots of individual lines that scan down the screen, refreshing about 25 frames per second. Because of the way your brain works you interpret it as one smooth image.
A camera takes only a very brief image of this so doesn't capture the whole image all the time.
If possible set your shutter speed to a lower speed (i.e. shutter is open longer, so will see more of the picture on the screen) and see if it helps. If you can't manually alter the shutter speed try turning off the flash (this will often force the camera to slow the shutter) or set it to night-scenery mode or similar.

The TV takes longer to refresh than you are leaving your shutter open. Try slower speeds, like 1/15, 1/8 etc., until you don't get those black bands. I've also found that you get the best image if you let the TV refresh twice. This would mean using 1/8 or slower. And a TRIPOD! It helps to use the camera's self-timer at these low speeds also, so you don't shake the camera just pushing the shutter button.

The lines appear in photos and sometimes on video because you are actually slowing down or stopping the wavelenghts on the screen. Your T.V., and even your computer monitor (except for LCD) broadcast the images in this way. Think of a field that has been recently plowed. Now picture the same field as you are driving by at a higher speed.....the valleys and mounds in the field disappear producing a flat surface. And believe it or not, it was actually a farmer who invented the T.V.

the thick black lines are in fact the mega pixels. Try not using a flash or making the room a little darker but not to dark so the camera will not be able to see the mega pixels on the tv

its because of the TV & Camera refresh rate.
leave the shutter open longer

Hi, I recommand you to try google picasa.

the pixels in the screen are always changing - the camera snaps it at an exact moment. They change too fast for our eyes to notice.
Damn pixels!!
