  • your problem is in the vertical output section as you have already mentioned that compressed down to 3 inch
  • if is is some times then you will have to check
  • loose contact in electrolytic capacitor in vertical output section
  •  it will be dry or some print cut must be there.you solder it.
  • it is best thing to replace all electrolytic capacitors in vertical output stage.they are hardly two or three.
  • it is a common failure,& not a major problem.
  • as per location of the suspect is concern it in the section from where the wires are going to crt neck.
  • hope this will help
  • good luck

Hi I had the same problem. Broken white lines across the top of the screen. This is called overscan. You need to go into the Setup menu, other settings. 16:9 overscan needs to be on. Hope this helps.It solved our problem.

Horizontal lines center of Panasonic HDTV


Usually there is a capacitor in the pump up circuit and/or an IC in the vertical circuit that causes this problem. Contact Panasonic at: http://www2.panasonic.com/webapp/wcs/stores/servlet/vServiceLocator?storeId=15001 To find a servicer in your area. This will give you an idea of the cost of repair. Hope this helps.
