You have some bad grounds on the Vertical IC. In addition to this, in the immediate area of this Vertical IC, are a few bad capacitors. Look for this IC mounted on a large heatsink. It may have seven pins . I cannot remember for sure. I have not worked on this particular TV, so I cannot give you specific locations. But I assure the problem is in this area! If you have some electrical experience you can pull this board out. In this case only the caps need replaced and the IC resoldered. Good Luck and thank you for asking. If you have anymore questions, visit me...Thanks Again! Your south of the border tech!
vertical output ic needs to be resoldered. careful leaving that bright line displayed on the screen as this will cause a permanent phosphor burn into the tube. this can not be corrected once burned unless you replace the tube. mch
A line on an LCD, either horizontal or vertical usually means the video driver board is defective or the screen is defective, does it show up as black even on a dark screen? That means a line of LCD "shutter"s is not working and there is a problem that cant be fixed by a reboot or channel change. Bummer.
First of all, there is no such thing as a "high power flyback converter". There is a flyback transformer, but if it was bad you would have absolutely no picture at all. The fact that you dont even know what the basic components are suggests that you should not be "diving in" to someone else's TV. Do everyone a favor and allow an experienced tech to service the set.
sound like the screen control on the flyback is set just a little too high. the flyback has the red wire attached to the tube. the flyback has 2 small adjustable controls. if you look close enough 1 is marked focus & on is screen. turn the screen slightly to the left & look at your picture. the screen is like a master brightness & if it's up too high you will see what is called retrace lines.
