My led samsung tv has a horizontal line and the upper right corner shows a white vertical lines

Not good. You may have a tab failure. A repair shop may be able to diagnose and repair this, but most likely the lcd panel is broken. The panel is the most expensive part of flat tv's. A new panel will cost more than a used tv.

Sony Bravia KLV-40U100M-screen is distorted, overlay or various vertical lines

The resolution on this was to check the surge protector the television was plugged into. Once we unplugged and plugged into another surge protector, the screen went back to normal and the appearance was great. We believe this was due to one of the resistors within the surge protector may have become faulty.

Brown horizontal lines sporadically appearing on monitor

I had the same problem. I fixed it completely today. The horizontal lines disappeared. IT IS DEFINETLY THE DEVICE DRIVER. I confirmed my monitor model tyope (dell M783s) and downloaded the specific driver for this monitor.

I had to do these exact steps or did not work.
1) with the problem screen, disabled the display adapter under the Hardware/Device Manager settings.
2) Restart the PC
3) Boot will come up with brown lines still but the screen will low resolution of 600x800.
4) Then I installed the correct device display monitor driver onto the pc. ( you may need to scan for new hardware, then choose the directory with the new hard drive.)

If you need step by step... just reply back.
