      Looks like your verticle oscillator, verticle amp transistor or a bad yoke. check the verticle amp transistor first. be sure to unplug Tv and discharge the CRT. They can hold a charge for days. use a HV probe or a long screwdriver through a 3 to 5 watt resistor to chasis. before putting your hands in there. CRT can hold a 35kv charge with a
      fair amount of current when discharging

        I should have mentioned our family used to have one of these TVs same exact model make sure you don't have cold solder joints on the vertical oscillator or the vertical output transistors also there are some fairly large heat resistors and the solder could be bad underneath the board there. basically go see the mainboard make sure that you don't have any cold solder joints
        Did I leave the soldering iron on?

          ok re soldered the flyback and found the low voltage fuse was the culprit the lines are now gone from letting it wake up it does need a bulb color adjustment bad as i can see the red and blue need to be adjusted the place where i brought it said o its no good and it cant be fixed well i fixed it so i'm gonna call them tomorrow since i paid $75 for service i'm gonna make them adjust for me free of charge . i did what i could to adjust it but yeah nes with battletoads lol..

                doesn't that TV have screen and drive djustments or is it software driven. Service menu? The crt may be weak.

                  I think that's too old to have a service menu. It'll likely be full of trimpots.

                  A working TV? How boring!
