well.. i had one of my friends come over and adjust the tv while it was on. hes clueless about them but he has no fear being back there while its on

anyways, i put a tape in the vhs and he was turning the color killer slowly and i got a black and white picture still, but there was stray color in the picture. he touched the vertical lin adjustment in the back and the picture came in the best it has yet, black and white with stray color. i guess this is progress?
