Many black vertical lines, 1/8" apart across whole screen.

Hello,

My TV has about 200 thin vertical black lines (!3 px across each) running along the length of the screen, perfectly spaced ~1/8" apart. They are clean, not "fuzzy" and are still, they don't move across the screen. In some parts of the screen when a strong color comes on the screen (usually a dark color) they will disappear and show that small portion of the image perfectly, ie: not dead pixels.

As I googled around I have not found anyone else presenting with this issue. It's typically a single or few lines running across, and that ends up being a broken capacitor or poor internal connection by the sounds of it.

Anyone have any ideas?

Thanks for your help!
