SOURCE: Zenith LCD Flat Screen TV just shows vertical lines of color
Press menu button on the TV if the on screen display is also distorted or no pic the TV is definetely defective. You can try unpluuging from wall for about 15 minutes and see if reset helps if not problem is either main p.c.b , LCD panel , LVDS cable or Power supply board. and would require service. most likely problem would be bad connection at or defective LVDS cable that connects main p.c.b to Panel (cheapest fix) or defective main p.c.b. If it is the panel it would probably not be worth repairing and you may want to sell as is on ebay.
SOURCE: Verticle lines following the color spectrum across the screen.
B Block assy from Sony direct is about $890. It has a core value of $525 for the old part, so once you get credit for the old core, the new B Block Assy really costs you $365. Still too much, but not as bad...
SOURCE: plasma TV with vertical lines
Help! My Plasma by Magnavox is putting black verticle lines on the right side of the screen - comes and goes - and I replaced the entire Direct TV-HD unit - wires, everything - and had TV company repair - and it still came back. The TV repair refuses to take TV back because it does not show up when they come. Although I videotaped it and showed them which has the date and time - they still refused to take it - and tried to get me to sign a paper saying it was working while they were there - which of course I refused to sign - so they left and nastily said they will not be back-find someone else. I still have the lines - and do not know what to do! Can anyone help?

try to go to the factory reset and see if that helps. If not, you can then check your connection. if you use component (red, green and blue for video and red and white for audio), make sure all the color matches when you plug it in. if everything have been checked then you need to replace the main board and it should correct the problem.
