I have a dark area in my LCD TV - center top extending down to about mid screen. it is shaped like a little tornado. It is more noticable on darker background. What is it and what will it take to correct?

SOURCE: images go suddenly darker

Turn off the the OPC feature in the Menu. If that doesnt help, what youre seeing is most likely the Advanced Dynamic Contrast going to work. In layman's terms, it automatically adjusts the contrast depending on the video signal it is receiving. If you want to disable this, change the AV settings to "User" (button underneath the bottom door on the sharp remote)

SOURCE: I have a 37in LCD

sounds like a failed backlight or inverter.
larger LCD sets use multiple lamps horizontally across the screen.

SOURCE: My tv has perpendicular dark lines

theres a possibility you left it on to long and it over heated or the tv is just to old and need replacing. average life for flat screens are about 5 years

hi, usually you can correct this issue with only a few system checks, dark streaks can be caused by damaged pixels on the screen, in which case you need to replace the TV.
  • Inspect where the dark streaks are on the television. If the streaks occur at the same place on the top and bottom of the screen, they are due to the formatting of a movie or television show you are watching. This is normal. Also, if the streaks appear on the left and right of the screen, they are due to the show being filmed in full-screen instead of wide-screen. This also is normal.

  • Change the input setting so you are viewing the contents of a different device. If the dark streaks are gone, you know they are due to the device connected to it. However, if the dark streaks remains no matter what input the TV is connected to, the problem lies with the television.

  • Inspect the cable connection. Oftentimes when connecting a computer to an LCD TV, you can have strange dark streaks across the screen. Use a DVI-to-HDMI cable connection when plugging in your computer, then press the "Menu" button on your TV remote, select "Picture" and chose "Square Pixel." See whether the image adjusts and the dark streak goes away.
  • Contact the manufacturer of your LCD television if the dark streak remains. This streak can be caused by a defect in the television; if the TV is still under warranty, you can have it replaced.

    Shadows on screen

    Try moving a medium powered magnet (not one for picking up heavy objects and not a refrigerator holding one) over the distorted area. If that doesn't work, try a more powerful one. This worked for my Toshiba LCD. Good luck!

    I had the exact same issue. I bought a new tv for my family room and moved the Sceptre to a seldom used location. When I did turn the Sceptre on after a couple of months, it was good as new. The dark areas disappeared completely

    Dark black spots around the edges of LCD TV

    this issue is tape from the edge of the panel falling onto the screen.You will have to remove the cabinet and the panel from the bezel(front cabinet).remove the screws from the lcd outer edge. Take of the tape.Be very carfull of the ribbon cable that goes to the lcd controller and to the lcd screen itself. They break easy. If you do , its over. you will need a new panel. to much money and work. best to leave it alone.I have fixed it several times for people with warrentys. It is just anoying but will not hurt your tv.
