    I recently bought a Samsung TSl3294 HDTV ready TV. It worked for about an hour and then the colors went out of wack. First it dropped colors and it finally ended up looking like an old 8-bit image from the early days of the Internet. Finally the audio dropped out.

    A friend says its the comb filters. Is there any way to adjust them?

    Thanks

    A comb filter seperates chroma (color) and luma (b+w) signals on composite sources. If the source is being fed via S-Video or Component, than the comb filter shouldn't even be active.

    Maybe its not the comb filter, its happening with video sources from cable/co-ax, S-Video and composite.

    One of the first symptoms was bright white saturated highlights turning black. Such as reflections on people's faces.

    Any ideas I'm going to return the TV soon if it can't be fixed.

    If you can exchange it, just do that.

    Never heard of anything quite like this before. Good luck!
