Open Question

Black bars on right side of screen that stretch to the left...

Black bars started showing up on the right side and stretch to the left. When it first started it took 10min for it to clear up. Now 3 months later its alot darker and takes 30 minutes to clear up. When it first showed i called SONY and they said "Its 3 monthe past the warranty sorry" A tech friend told me some board has to be replaced. But the board it attached to the LCD so basically the WHOLE LCD has to be replaced. Whats funny SONY NOW makes that board SEPERATE from the LCD..mmmmm Maybe they know it fails..I paid over 3000 for a SONY product that I believed in. **** i still have a SONY from 1977 and another form 1989. And they work fine...So i guess SONY now makes TV's with a 13month life span..I will NEVER purchase a SONY EVER AGAIN! Keep posted When it goes out for good I am going to do something to it and post the VIDEO on youtube...

To be honest, it won't be a cheap repair. You could be looking at an aging backlight inverter or possibly the CCFL bulbs that light your tv are aging as well. The backlight inverter would be nearly $60-$90 and the CCFL bulbs are close to $20 each @ 12-14 of them.


Please rate if this helped :)

Any advice on what board I should replace if the left half of the screen is no good, just showing white and black vertical bars? Right half is fine. Is the panel kaput?

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.

SHARP AQUOS 46INCH CANT GET A FULL PICTURE ONLY IF I USE ZOOM WILL THE SCREENBE FULL


Hi Anthony,

You're describing what is called letterbox and pillerbox. Letterboxing is when there are two horizontal bars - one at the top and one at the bottom of the screen with a wide picture between. Pillerbox is when there are two vertical bars - one on the left edge and one on the right edge of the screen with a tall picture between.

The settings on your TV (and on your cable box, satellite box, DVD player, etc.) tell the TV how to display a picture that will not fill the screen completely. If the program source (an older video-taped TV show, non-widescreen version DVD, etc) was not originally "shot" or saved in widescreen format, the TV offers you a choice on how to display the image. They ask if they should stretch or zoom to fill the screen (and you have to deal with the skinny / tall images or lost portions of the picture); or maintain the aspect ratio (not stretching or zooming) by leaving a part of the screen blank (grey or black) by inserting bars left and right or top and bottom of the screen.

Start out by telling the devices that send pictures in a format that matches you TV's screen ratio. I am assuming you've got a wide screen HDTV which would mean it should be set to "16 x 9" (a.k.a. 16:9) ratio display. If you have it set for 4 x 3 (a.k.a. 4:3) you should change it. Look for a setting on your TV that asks about stretching, zooming, etc. as this will be an issue when receiving picture from an off air antenna on your house when a TV station is airing an older, non-wide screen format TV show or movie.

TV signals provided by Cable TV or Satellite provider must be HDTV type signals. If you have the standard TV service (non-HD) no picture sent by them will ever fill the screen. This is because Standard Definition TV (SDTV) is not capable of those types of signals. You will have to bump up your subscription to HDTV service to get full screen pictures.

I hope this helps!

Black bar on the top and bottom during watching the tv


Hello

If you are watching television and you see black lines on the left and right sides of the screen, check to see if you are watching an HD broadcast or a standard definition broadcast. You can do this by bringing up the TV guide menu on your remote. If the show is in HD, it should take up the full screen. However, if it is not HD, bars will be present on the left and right of the screen. That is because standard definition programing is in 4x3, which will not take up the entire screen.

If the picture you are watching not only has black bars on the sides, but on the tops and bottoms of the screen as well, your "Zoom" mode has somehow gotten off-kilter. Press the "Zoom" button on the remote until the image appears correct. If this does not work, power down the television, wait a few moments, and power the TV back on. The image should be correct now.

If the image on the screen looks stretched or squished, this is because your HD cable receiver is not set up properly for your widescreen television. Press the "Menu" button on the receiver

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.

3 inches of black on both sides of my monitor


I have seen this when using HDMI cables from the computer side.. The TV has a resolution that is not always full screen with TV shows. There is a setting that allows you to "zoom". My TV has 4 settings: normal, stretch and crop, stretch left and right, stretch and pinch (shrug).
