Zenith LCD Flat Screen TV just shows vertical lines of color

My TV Screen suddenly lost the picture and only displays vertical lines of color. The audio is fine. I called the Cable company and they performed some diagnostics and told me that the cable connections are all working.
What could be the problem?

    My 31" flat screen has fading colors on the picture. The sound works fine. If I take my finger and draw on the screen I can actually see the color follow my finger.

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.

Vertical Lines on Sony Bravia TV.


I'm afraid, its problem of LCD Panel (screen).
LCD Panel replacement is only solution for this problem and will cost you 70% of TV price, please contact nearest Sony service center for LCD Panel replacement.
