Replace the T-com board. That's where the problem is.

SOURCE: Dell Inspiron 1501 screen half black

Had the same problem. Fixed it though. Here's how:
You'll notice that the screen comes back to life if you press down on the very top of the green line. This is because a controller circuit board behind the LCD screen (at the top) is pressure fit flat-surface-to-flat surface to the contacts on the back of the LCD. Eventually, the sticky substance that holds this circuit board in place wears thin, collects dust, etc.. and the connection between the circuit board and the lcd contact is lost. The line appears where this break in contact has occured. 
So, the solution is to increase the pressure at that point to reestablish the connection. I wasn't able to remove the circuit board to clean beneath it as it seemed too likely to cause damage. Nor would I have had the right adhesive to connect it back, so I simply removed the LCD and put a bunch of tape at that point so that it would "push" with a little more pressure when screwed back into place. Worked great.
To remove the LCD, pull off the 6 feet around the screen. Remove the screws behind them. Carefully pry off bezel with a small flathead screwdriver working your way around it. Once removed there are simply 4 screws on the left and 4 more on the right of the LCD to remove. Pull out screen carefully and start stacking bits of tape on the spot where pressure seems to work best. Put it back in and see if you've made any difference. I did this with the computer on so I could verify my results. Just be careful not to short out any naked contacts.
If this doesn't work for you, at least you'll know you just need to replace the LCD, not the video card. Easily found on ebay.

It sounds like an Intergrated Circuit (IC) has fried. Even on a good day, this is not something you can attack at home. As a tech (and as an owner of that model samsung), I'd need a map & tools to know what's going on. Your best bet in this situation is to contact Samsung and let them recommend an authorized service center in your area. Sorry I can't be of more help, but this is a rather serious problem.

SOURCE: i have an lg 42inch plasma and now a vertical blac...

I had the same problem with a five year old 50" LG Plasma. I fixed the problem with a 11 dollar soldering iron from Radio Shack and about 2 hours of my night. You have to open the back of the tv and locate where the ribbon strips are attached to the screen. I beleive that on your 42" they will be on the bottom of the tv. Mine had 11 on top and 11 on bottom. Yours will probably have around 7 or 8 along the bottom. Mine was a little easier since I did not have to remove the control board. You unfortunately probably will have to remove it. It is not hard at all, just takes more time. Make sure to keep your screws seperated and remember where everything goes. On bigger jobs some tape and a marker are very useful. Put tape on the board and around the wires removed and leave a tail. This way tou will remember to hook them all back up. Once you find the ribbon strips you have to remove them one by one and look at what is behind the metal place. There will be 4 capacitors and 4 resistors. The tv manufacturers want you to buy new tv's every 5 to 10 years so they use a very cheap solder on their contacts. Use you soldering iron and re-heat the solder to liquify it again and thats it. Allow time to cool on each of the caps and resistors. It took me about 1 to 2 seconds on each side of these parts. I did use a dual wattage soldering iron from radio shack. Its is a 25 and 35 watt iron. I used the higher setting. I have pictures if you would like me to email them to you and show you what I did. Be careful removing the ribbon strips, I broke one of the clips that hold in the ribbon strip. That is costing me an extra 25 dollars off ebay but still for a free tv, its not bad.

CHANGING THE SCREEN ASPECT RATIO: ( From Manual )
The TV can display images in four different modes: Wide, Zoom, Panoramic, and Normal. Each mode displays the picture differently. To change the screen aspect ratio:
1. Press the MENU button on the remote.
2. Use the Arrow buttons to highlight the Wide icon. Press OK.
3. Use the Arrow buttons to highlight your desired screen mode and press OK:
• Normal preserves the content's original aspect ratio. Since the 4:3 aspect ratio is not large enough to fill the TV's screen, black bars are added to the left and right of the display image.
• Wide stretches a 4:3 aspect ratio picture to the edges of the screen. Since the picture is being stretched, the display image may appear distorted. If the program is already formatted for widescreen viewing (1.85:1 or 2.35:1), then black bars will appear on the top and bottom of the display image.
• Zoom expands images with black bars to fit the screen.
• Panoramic expands the display image to fill the screen.
images may appear wider than intended.
If you are watching widescreen (1.85:1 or 2.35:1) content, black bars will still appear on the top and bottom of the display image. This option is only available when the TV is displaying a 480i/480p source.

How to zoom in on info


When TVs first appeared, they had an picture ratio of 4:3, which matched that of most movie screens at the time. Terrified of losing their business, movie studios struck back with "widescreen" films using 1.85:1 or 2.35:1 ratios. When widescreen TVs started appearing, they emulated those same ratios, but many TV shows (and some movies) were still in 4:3---and we were eventually left with a bit of a mess. Canny manufacturers, including LG, have solved the problem by allowing you to adjust the picture ratio on the TV to fit the program you're watching. If it's not set properly, however, your image will look distorted or cut off. A quick bit of troubleshooting can fix the problem easily.

  1. Press the "Menu" button on the remote and scroll down to the "Option" title (it should be second from the bottom ). Then select "Aspect Ratio." You should see a list of ratio options. You simply need to pick the one which fits the show you're watching.
  2. Choose the 4:3 ratio for older movies and TV programs. You should see a pair of bars on the left and right side of the screen. (That's okay: the bars keep the program in the same proportion in which it was filmed.)
  3. Select the 16:9 ratio for widescreen movies and for more recent shows to match their longer width. For some movies, you may see black bars and the top and bottom of the screen. Again, that allows the movie to be shown in the manner it was filmed.
  4. Pick "Set By Program" to automatically switch the LG TV between 4:3 and 16:9 to match whatever show is on at the time.
  5. Select "Horizon" to horizontally expand the image onscreen. It will fill the whole screen---eliminating the black bars to the left and the right---but it may look distorted.
  6. Use the "Zoom 1" option to zoom the image forward. That will eliminate the black bars at the top or the bottom of the screen, though you will cut off the edges of the image.
  7. Pick the "Zoom 2" button to select a midway point between "Horizon" and "Zoom 1." The picture is stretched, but not as much as with "Horizon," and fills the screen, but doesn't cut off as much as "Zoom 1."
  8. Use the "Cinema Zoom" button to enlarge the picture to fit the screen. This option allows you to adjust the proportion to your liking, rather than use the set proportions of the other aspect options.
  9. Exit the menu when you are done and watch your programming normally.

Screen shuts off. Power lite blinks. Aquos 42"


Hi,

Hope you have the correct resolution selected:

HD View Modes: When viewing an HD program you can select the following 4 viewing modes.
  • Stretch: suitable for viewing 1.78:1 DVDs. When viewing 1.85:1 DVDs, this mode will show thin black bands at top and bottom of the screen.
  • Dot by Dot (1080i/p only): detects the resolution of the signal and displays an image with the same number of pixels on the screen. When a 720p signal is being input, the image will be delivered in full screen.
  • Smart Stretch: suitable for stretching 4:3 programs to fill the screen.
  • Zoom: suitable for viewing wide-screen 2.35:1 aspect-ratio programs in full screen.
PC View Modes: You can connect the TV to your PC through the HDMI inputs to use the TV as a monitor. The following view modes are available in PC mode.
  • 4:3 Input Signal: You can select between Normal, Zoom, Stretch, or Dot by Dot.
  • 16:9 Input Signal: You can select between Stretch or Dot by Dot.
Also verify if you have set auto timer to 30 mins or so thats why the TV shuts down after a particular time.

Thanks

Go to your TV settings and change the "Zoom" function (not sure if LG has same terminology as my Sony) - you can flip through different options until you get to the setup that does not "stretch" the picture to fit the screen - if certain shows are filmed in 4:3 format (or square), they will need to be displayed with two black bars on either side (letterbox) on a widescreen set so the image is not distorted or stretched.
