Hello,
Could somebody explain to me what is wrong (technically) with a device when it outputs analog video with vertical "bars" such as those indicated by arrow #1 in this example:
vertical bars
These bars are static - they don't move when the image is on the screen. Doesn't look like typical interference (wavy lines, etc...). Coincidentally, the lines indicated by arrow #2 do move, but they can't be seen with a naked eye as easily as they could with the camera that took this picture.
The vertical bars really show up a lot on blues, but can be seen in other colors as well. They are thin and are present across the entire image.
Is the chroma signal not timed correctly? Too strong? Not enough? Help me out here.
Thanks!
CK
