It could be one of two things. One of the bottom buffer boards could be bad or the lcd itself is bad.

Vertical red lines on screen


LCD correct?

There are 2 types of lines they may be showing, both requiring the replacement of the LCD Panel.

1. Delamination Lines- they are usually multiple vertical lines that do NOT flow from the top to bottom of the screen. Looks look water dripped down or something similar

2. Single/Multiple Vertical lines - This is normally 1 or maybe a few solid vertical lines that travel from Top to bottom. I belive in some cases they may only travel to the screen center.

In both cases, this will always show when the TV is ON. Even if there is no signal being input to the TV. There are other possibilities but these can be the most common. Both require a new panel.

Shadows on screen


Try moving a medium powered magnet (not one for picking up heavy objects and not a refrigerator holding one) over the distorted area. If that doesn't work, try a more powerful one. This worked for my Toshiba LCD. Good luck!

Green horizontal lines across screen


try adjusting the green screen control. remove the front bottom panel of the tv by removing any screws holding it in place. gently pull of the front panel, there are gromets holding it in place, you will be able to gently remove the front, just make sure you get all those screws. now reove the small wodden or plastioc panel. now you will see the screen/focus assy. check to see of the screen controls are the top 3 or bottom 3. adjusted the center screen it's the green one, the other 2 are the red & blue. it is best to adjust in a dark room where the lines will show up easier. good luck

Screen split with black bar through center, top of picture shows in bottom


It sounds as you desribe, the vertical output IC and or the b+ feed capacitor off the Hi voltage transformer feeding the vert. IC its required voltage. Not a really hard job to replace, but not for a handi person to do. This should be left to the professional, as there are no user serviceable parts inside this set and with the HI voltage and the safety issues its best to call somesone to assist you with this repair. Good Luck
