If the set is only a few weeks old you should put a claim for a warranty repair or exchange I believe is the back light(lamp)doing the flickering and should not be doing that at all and it will not go away by itself,it might get worst. Let Us know how it goes or if you need more information.

This sounds classic to a thermo problem where a part(s) are becoming thermo sensitive with aga and use. When the set is cold and then warmed up, the defective part(s) is changing characteristics.
Some components became thermo sensitive that are driving the display. Or an embeded component in the display itself became thermo sensitive. It is very possible that the fault is on the board that does the X - Y addressing or on the backplane electronics of the display screen itself.
Using the set with defective components is a bad idea. If the part(s) fail completely and go shorted or opened, other more costly damage can be done.
The service rep for the manufacture of your set is equiped and trained to be able to troubleshoot and service your set.
You will have to take the set in to have it serviced.

I had this problem on a 37" Viewsonic LCD. Pulled it apart and through a process of elimination, I traced the problem back to a small board with several flat white ribbon cables coming out of it. The board was near the top center of the screen and under a ton of other equipment requiring almost a total disassembly.
This small board was clean but I noticed one of the rubber standoffs had slipped down and was making contact with one of the outputs running to the LCD. It also happened to be the output running to the section of the screen with the problem.
I postulated that the sticky glue on the rubber standoff may have just enough conductivity to cause a problem. Moved it so that it was no longer touching anything electrical and then reassembled the TV.
Afterwards, I turned it on and was pleased to see the problem has gone away! If you're having the vertical line problem, then maybe this could be your problem too, especially if you have a Viewsonic since it could be a manufacturing defect.
