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 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.

    Blue Streak at bottom on LCD TV screen

    Most likely being your television being on something too long and now it's burnt in, you can leave a non-moving object on your T.V. too long, the channel icons are okay because of the commercials. There's really nothing you can do now.

    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.
