    Exactly as described - a dark grey vertival line approximately 130mm from left hand of screen and another about 220 mm from the right side of the screen.



    Looks horrible

This is a hard one without seeing the actual defect. It sounds like there is a problem with the processing board. It could be as simple as a poor connection inside at a cable connection. The signal levels inside these sets is very low and any dirt or dust in the connection area can cause "noise" on the digital data lines that can show up in odd ways like you described. If the set is no longer under warranty, you can try reseating all of the cables and connectors inside the set. That may resolve the problem.

If not, try to post a picture of the screen here and I'll try to give you more options.

Hello there! the best possible thing you should do is contact the company wherein you have purchased of your appliance..because some of the components of certain appliances are mostly recondition and thus easily destroyed.

I have a long black streak with black circle on my laptop


Your statement is a bit vague, I assume it's the Monitor? Sounds like it's been damaged, is there a part you left out?

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, My Canon 3245 Imagerunner is streaking.


Hello,
First, the streaks appears when copy from glass or adf, when printing or all?

Solution #1:
How many copies did you do from last drum changing? if over 80 000 copies, replace the drum unit.
-in case that streaks appears when copy and print

Solution #2:
If the streaks appears only if you copy from adf or glass, clean the glass and dry it out. Both glasses, narrow on left side beneath the adf/cover and glass for copy of original.

Solution #3:
If the streaks are wide and solid, with possible toner left overs, you need to replace fixing film.

Hope that helps!

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.

    Issue with our Toshiba 50H82 - overnight it has stopped playing DVD's properly - a solid black rectangle obliterates 75% of the screen. Any idea?


    Hi,
    Do you see same solid black box in all inputs or just in dvd picture?
    If solid box appears only with dvd picture then its generated by dvd player, check dvd player Menu and turn off any subtitle settings.
    And if solid black rectangular appears in all inputs of TV like cable etc then check Close Caption feature in TV and turn off CC function.
    Hope this will solve your TV problem.
    Thanks.

    Streaky copies


    It probably has several issues - optics dirty, and drum, and blade failing. I would also imagine that even the Solid "blacks" aren't as black as they could be, and that would be the developer. This machine is in the 17 year old range, and I wouldn't spend dime on it

    Blue Streak


    I had the same problem w/ the same TV about 6 months ago. You need a new optical engine. Hopefully you are still under warranty. Once that was replaced, the tv looks great.
