    If you have like a black stain of ink inside the screen , then that is a broken LCD.

    If you get signal disturbance and spots , then it can be either a lose connector, or a problem on the main pcb, that controls the signal.

Dark line down the middle of my flat screen tv


Most LCD and PLASMA sets use two boards (some combine them into one board) that drive the Display Panel (the entire front screen unit) so I would suspect one of yours is bad.

The other unpleasant possible cause is where the left board is connected to the Display Panel (entire front screen unit) you have a problem inside that Display Panel and that is fatal as there is no way to get INSIDE the panel---it can cause both lines and a dark picture on one side of the screen.

I have three black circles, and some color streaking at he bottom inch of my RCA, LCD tv


that is usually caused by cleaning the screen with windex the windex runs down the screen bewteen the screen and plastic frame and actually seeps inside between the screen layers. Eventually it may go away by itself if the circles are not too bad but in most cases the damage is permanent.It can also be an issue called screen delamination which there is no fix for.

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.

    Dark run looking spot of screen


    Probably a bad backlight tube. It would look like a darkish about 1" (2.5cm) wide streak running near to horizontal part or all the way across screen.

    This will most likely be down to your screen controller board, Take the back of the tv and look towards the top middle, You will see your screen cable go into a rectangular board this is sometimes covered by a metal plate, remove this and check Ebay or Google for a replacement, there will be a part number on the board
    Hope this helps?

    Vertical black band down middle of tv screen


    If you are able to see a complete picture though darl in the middle where the band is I would suspect a back light problem or an image processor problem, if the band is totally dark(dead pixels) you can not see a picture in the same area then you have a defective screenand has to be reolaced.

    Dark shadow-like vertical streaks thru LCD screen (Sharp)


    Hi, I have a Sony Grand Wega LCD Projection TV that has a blotted gray streak across the front of the screen. I only use a damp cloth to clean the window and that doesn't seem to help. It really shows up on light pictures and is unnoticed when the picture is a little darker. What can I do to fix this problem???

    Shadow on Flat Screen TV


    Projection TV correct? This may take some work but it is common for a spec of dust to settle onto the Mirror inside the TV, The back side of the TV screen or onto the Lens from which the Video image is projected. Some TVs have ports that allow you to access the inside of the TV from the side, others you must remove the screen.

    This is not something to do every day or every week and it will not improve the picture. You only do this when you notice that it is dirty. Any more than that and you yourself will create a bigger problem. ONLY LIGHTLY DUST the screen. Soaps, water and windex will leave streaks, damage the screen and cause more trouble.

    Projection TVs are the eqivalent of a big flashlight showing onto a wall. Put you hand in front of the light and you get a shadow.

    Inside you TV there is a light (the TV picture) that bonces of a mirror attached to the inside of the back of the TV. The light reflects off the mirror onto the back of the screen. You view this refelected image from the front. Spiders commonly make webs inside the TV that appear in the picture. Dust Bunnies may get blown into an area and become stuck in the way. Sometimes a lite tap, shake or blow may remove this also.
