If vertical lines are displayed to plasma displays, the fault should be with COF boards. These units can be located at the bottom side of the screen [in a row]. If its connection to panel become loose, this type of fault can occur, and is my experience. Check all the COF connections first. See whether IC used on each COF is damaged or not. You can't check it by using a multimeter; only can do a visual-test, whether there is any break or small holes on this IC. If you wish to get more details, check the site linked here. It has screen-shots to fault plasma displays. You can note it, and compare to that of your TVs' screen, and make sure about the fault.

Horizontal line running through the middle tv screen, no picture but has sound. TV is a Toshiba.


You haven't vertical deflection.
The ff caused the problem.
1. Dry joints on the vetical section.
2. Blew Vertical ouput IC
3. Open yoke vetical winding.
4. No vertical output from jungle IC.
5. Open supply for vetical ic due to open fusible resistor.

I've suspect that you have #1 and #2 fault. This is not Diy so I've advice you to send to repair shop or look for a qualified tech to isolate the problem.

Thanks for using fixya.
