Hi, you're one of many people with this problem.
The problem is the Inverter transformers on this board here:
You can see 6 of them lined up in the front of the board. The windings in the Inverter Transformer are very small copper wire that breaks easily. My new TV lasted 4 months until this problem occurred. I had to solder in a new Inverter to fix the problem.
The board number is BA71F0F01042.
The board is hard to find right now. Only three places I know of to find it.
You can replace the whole board or replace the bad Inverter to fix the problem.
Let me know if you need any more help.

Hi, Depeending on the thickness of the lines matters. If the lines are Black and about 1-2 inches thick it may be a bad bottom buffer board or a bad panel (screen).
If the lines are thin 1/16 to 1/8 inch it is most likely a bad panel.
You can open up the set and depending on the model, see the thin board/boards running across the bottom with ribbon cables going to the panel. You may be able to attempt reseating the ribbon cables, but be careful as some retainer plugs break very easy.
If the lines are thick black and the reseating doesn't correct it you may be able to buy the coresponding buffer. Unfortunately some bottom buffers are actually part of the panel. If you are not comfortable taking it apart then call a professional but be aware labor charges start around $200 not counting parts, panels start at $600 up to over $1000
hope this helps

I don't know anything of this particular TV, but what you describe is generally a known problem in LCD displays.
it's caused by one of two things - either parts of the LCD film thin film for the vertical lines detatching from the board it is glued on or certain micro controllers that are also glued on the LCD film starting to get burned bit by bit. In both cases, the whole vertical line responsible for one of the three colors that a single pixel consist off get dead and depending on how they get dead they get either all open or all closed, respectively completely turning on or shutting off the particular color.
It is most commonly the first case, but whichever of the two it is, there's no known cure for it within reasonable cost.
I've experimented a few times and was able to press the film to the board by using firm objects and fastening the display case, but it would often cause more harm than it brings and even more often it would just not hold reliably. Overall I do not recommend experimenting with it it unless you have lots of time on your hands and you're ready to face an evern worse damage.
In a very rare cases it might also be the tcon also known as LCD controller...but from what you describe it's hardly it. It's worth trying, but if I had to take a guess I'd rather rule it out - it sounds like the LCD.
And the bottom line is you just have to face it - you likely need a new TV. If there's some chance for me to be wrong, try the tcon board at the back first. Then just sold the TV on eBay or CL for whoever gives you most and apply the money towards the new purchase.
Don't kill me, I'm just the messenger :-)
