Hello horrizontal ines are controlled by your buffer (drive boards) or your ysus board. They are located on the side of the tv and are 3 boards that are connected together and connect to the side of the plasma screen. the two drive boards separate the top and buton. if the lines are on the top then you might try replacing the top buffer and vise versa. if that does not work then its your y-sus. be very carefull replacing these they are very sensative.

Normally this is an overheating issue or a power supply issue. For the overheating issue, take a vacuum and some compressed air and blow out the back of the TV. Dust can collect and cause components to retain heat that will cause the TV to produce horizontal lines called artifacts. Sometimes these are permanent but sometimes they can be repaired before replacement.
HI, need to see a picture of the line and need to know if you see it on all inputs and whitch ones are you using and does it do it on all of them.
If you cannot send me a picture then let me know what color is the line,is it from left to the right end of the screen and the top and the bottom of the line are they straight all the way horrizontally.
Wait your response then I will do my best to find the solution.
hi there, is the single line horizontally or vertically? if horizontal line, you do have a vertical section problem, check some parts at vertical section, the vertical ic, the power source of vertical section ie diode & resistors. ty
1. HORIZONTAL PULLING AND TEARING, MAY ALSO HAVE VERTICAL ROLLING OR VERTICAL BLANKING BAR LOCKING IN THE MIDDLE OF THE PICTURE. CHECK C2C52 10 UFD @ 50 V OFF THE BASE OF Q2C51 ON THE SIGNAL PCB. 2. CHECK C2P05 100 UFD 16 V OFF PIN 3 OF IC2P01 (9-VOLT REGULATOR) ON THE SIGNAL PCB
If you're NOT still under warrantee you should at least open the TV and look for a blown fuse near where the power cable enters the set. A lot of times you can buy replacement fuses at a local electronic or hardware store and they're easy to replace.
Check the fuse. If it is blown, it will be obvious and make sure that the set is unplugged before replacing it. If it blows again you will need professional help with the repairs.
You can also check the board where the components are mounted and resoled any that look bad.
In your case it could caused by a blown fuse, a leaky diodes or a bad solder joint at the horizontal drive transformer.
All can be replaced at a local electronic or hardware store and they're easy to replace
If this does not correct the problem, you may need to have your TV serviced.
