If your LCD TV or monitor has stopped working, or is displaying one of the following
symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can
examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life
of your monitor or TV by several years.
Take it to a repair shop.

I've got the same TV with the same problem. Sometimes by moving it on the stand the lines will go away but it only sometimes temporarily fixes the problem. For a while it seemed like it needed to heat up to go away but that is not the case. It seems like there is a bad connection somewhere but i cant seem to find it. One day, one thing will fix it, then the next day it wont do the trick. It gets very irritating.
This sounds like a bad cap in the power supply. The component is only starting to fail under load and heat. I'll look up your specific model and see if there have been any reports of this type of problem.
my scroll bar does the same thing sometimes, it moves up and down uncontrolably without me doing anything. i just recomend restarting and making sure the connections are all right. after i did that it seemed to work fine, but maybe if it keeps happening then you may need to replace it!!
im pretty sure you cant fix that you probably need to buy a new one.. i know that because my somputer has a white line that runs right down that middle, not all the time but sometimes. my father looked into fixing it and he found out that you have to buy a brand new screen or tower or something like that.
