    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.

Dark streak on paper


you need to clean the rollers. consult the manual about cleaning the copier. if you don't have a manual, then get some methyl alcohol (any alcohol that evaporates completely will do). use a lint free cloth to rub a small amount of alcohol on all roller surfaces (accessible via pull-down compartments on front and back, usually).

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.

    The blue will not converge, how can I manually do it? The blue appears to be showing bottom left corner below the screen, like it got moved.


    I had the same problem but it wouldn't converge on the whole right side of the screen. I fixed my problem by taking off the speaker cover, removing the 3 allen 7/64" screws from the front of the bottom of the button pannel, then removing the 4 scew from the back of the pannel (2 on each side), and the button pannel should drop down. With the power on I cleaned the 3 projection lenses with many qtips dipped in alcohol. I left the TV on so I could see if there was any streaking on the lenses (streaking means it is still dirty). Once they were all clean and I put the button pannel back on, I went to the menu and ran the autoconvergence function. Now my picture is so clean. Good Luck.

    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???

    The dark picture is a bad capacitor for the screen or drive voltage for the picture tube driver transistors. The other problem of streaking is one of the same. Thats the indication that a capacitors defective . It could in a rare cas ebe a defective or gassy crt as well but 99% of the time when a crt is said to be gassy its nothing more then poor drive to the crt. Good luck
