I just opened the back of the set, and looks like there's about 30 years of dust, so I unplugged picture tube sprayed electrical contact cleaner on the pins and in the holes, also sprayed a lot of the controls, and it brought back the picture very well, The suckshon cup connected to the picture tube i noticed is loose, so i hear hissing when the screen becomes dark. Only problems now is certain parts of the screen has a slightly noticeable green tint and some other areas blue.. Red, blue or green bleeds very bad off objects on the screen depending on the color and back ground, bleeds less depending on color control setting, less color less bleeding. Also when the screen is blank (in between scenes or commercials) the lines are still noticeable...
