Sounds like a bad connection on a ribbon cable or plug comming or going to the LCD display. This is something you should not try to fix as these circuits are very very fradgile and you can easily break or tear a ribbon cable . Call the manufacturer to get a tech to assit you. Good Luck

SOURCE: green lines down length of screen on my samsung 40 inch LE40F8

The reason for the green lines are the resolution. I'm assuming you're TV is set at 1080i, not 720p or 1080p correct? What happens is the "i" stands for interlaced, meaning, your TV displays your images with scan-lines. The "p" stands for progressive, meaning, TV displays picture as a whole. You can not visibly see the scan lines when seeing 1080i, but certain TV programs are not outputting their show to the resolution you're at, which will cause you to have the green line up at the top of your TV. SOME TVs might let you adjust the settings to rid yourself of the scanline, but most consumer TVs will not let you without the maintenance code to protect your unit from over calibrating and braking your television. Hope this helps.

Look for bad caps with domed tops in the power supply module first, it may have dying power supply.

I cant play movies using my USB drive on my Samsung LCD tv model LA40D503F7R. Movies option on screen is not displaying, only music and pictures option is displaying


Nope, you certainly can't. The TV can only show still photos or play music. It's not capable of playing videos.

The manual is here:
http://www.samsung.com/ae/support/model/LA40D503F7RXZN
or
2011 LA40D503F7R 40 Inch Full HD LCD TV LA40D503F7RXZN Support SAMSUNG Gulf
See pages 16 and 17.

Burn your movies to DVD or Blu-Ray and you can plug a player into the TV, also described in the manual.

I have horizontal lines on the top 6 inches only all of the other picture is fine.


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.
Check the cables, connectors and connections.
Take it to a repair shop.

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.
