Line, faults & possible causes to both Plasma &LCD screen are given with illustrations. You can get an idea about the fault to an extent.
All monitors/TV's have Red, Green & Blue Drivers. When they are all on the screen = white. For some reason your red drive is over powering the others. Most of the time, it's a transistor or a failing capacitor depending on age .
Somehow when switching between the tv and the dvd my wife encountered the pink and green, thin, parallel, vertical lines on the screen. The picture was visible with the lines. I turned the tv off and on but the problem persisted. Unplugged tv for about two minutes and after plugging it back in and turning it on the vertical lines very gone and the picture was back to normal.
Do you have a green light that flashes and then goes off? You need instalation kit# 4835 310 57673, The chassis# is probably an L04.1U AA, correct? What you will do is correct the horizontal timing so everything will come on at the same time. After you install you will see red, blue, and green horizontal lines at the top of your screen.......this is normal when you power up your TV. This is a factory authorized repair.
This may be a power supply fault, and what you are probably seeing is some switching noise breaking in through the display processor, or possibly the input processor. Because of the fact that the bar is moving, this means that the sequence is not locked to the main processors.
You should contact the place where you bought the set and speak to someone about an exchange. A one day old set should be exchanged right away, and I would argue that fact.
I don't want to mention any name brands, but I would have gone for a company that also manufactures TV broadcast and industrial TV equipment rather than one that manufactures appliances.
Always try your extended warranty!.....Probable cause = bad red tube. One adjustment may help---turn down red screen control, located behind technician access panel in front of set.
try adjusting the green screen control. remove the front bottom panel of the tv by removing any screws holding it in place. gently pull of the front panel, there are gromets holding it in place, you will be able to gently remove the front, just make sure you get all those screws. now reove the small wodden or plastioc panel. now you will see the screen/focus assy. check to see of the screen controls are the top 3 or bottom 3. adjusted the center screen it's the green one, the other 2 are the red & blue. it is best to adjust in a dark room where the lines will show up easier. good luck
