This video covers how to fix a Panasonic 42" Plasma TV model TH-42PX600U that has vertical distorted ...
Unfortunately it sounds like the video processor or a capacitor inside the TV has started malfunctioning, causing the vertical lines. I recommend contacting where you purchased the TV from and ask for help regarding a repair or replacement if it's still in warranty.

Your best bet, if you have ther board out yourself is PTS Electronics. Techs even feed these guys because they're well known for their quality of work and reasonable price. If you're looking to have a shop there bring the whole set in and work on it maybe this will help. http://www.nesda.com/locator/state_search.php
sounds like X buffer/scan or control/logic problems. without good service info you will have a hard time troubleshooting. And it will get expensive guessing. Could even be a panel, probably gonna need a pro look.
Rakesh,
You have a "dual scan" panel, this is why the line only decends down the screen half-way. This could be a connection problem on the buffer board which causes loss of the drive signal only to that part of the display which it is connected to. The vertical address buffer will be located on the top rear of the display, use great caution in inspecting these cables and connectors. If the integrity of the cable and connector is good the panel itself may be bad due to the drive IC being located on the ribbon cable attached to the panel body. this is better known as COF or, chip-on-film technology. I hope this helps you. Good luck.
