Question about Toshiba Televison & Video

1 Answer

Toshiba 40BV700B - the screen has started to flicker with a bit of a double image up and down the screen. Eventually it freezes and sort of blurs up and down the screen.

If I get the menu up that flicker and flashes up and down the screen as well so I don't think it is not the television signal. It's like a double image of the top of the screen flashing on the bottom half of the screen.

    This is a picture of what it does on the screen. After this it sort of blurs red then goes black.

    Slight update. Now, when you switch the TV on the screen comes up blank. After about 20/30 minutes the screen starts to flicker like it does in the photo. Then after a couple of hours it settles down and is fine for the rest of the night.

Looks like either a TCON board failure or if you are lucky it could be a flex cable connection problem at the TCON or Main board.

SOURCE: Picture on Samsung LCD LNT5271F is blurred

Had this exact problem diagnosed by a local repair shop as a bad LCD panel. According to the technician there's a loose ribbon cable on the panel and it would cost as much to replace/repair as a new TV.

I have a Toshiba laptop.. completely new, and it was 700 dollars. When I go onto facebook, or clothes shopping, all of the pictures are blurry... but text is fine.


I understand that you are having the issue that you are getting Blurred Pictures while accessing the sites. To answer your query with the proper steps the information about the Browser you are using is required. If you are using the Internet Explorer you may follow the steps: Launch the Internet Explorer browser by double-clicking its Desktop icon or selecting it from the Start menu. Click "Tools" in the top menu bar of Internet Explorer. Select "Internet Options" from the drop-down menu. Click the "Advanced" tab and scroll down to Multimedia. Check the box next to "Smart Image Dithering." This will help to ensure that images are loaded properly. Right-click on the image in Internet Explorer and select "View Original Image" from the pop-up menu. This will force the browser to display the original image. Check to see if any installed Internet browsing accelerators are compressing your browsing too much and causing the blurred pictures. For example, the MSN Accelerator (used to enhance the speed of an individual's Internet connection) can sometimes cause blurry images due to high levels of compression. Right-click the "MSN Accelerator" in your Windows task bar (bottom right-hand corner of your PC's screen) and set the level of compression to "None." If you are using the other browser you may try resetting the settings. Even in Internet explorer you may reset. But note that resetting the Brower may deleted the saved information like password and auto fill.

For additional help if you need please revert back with the exact details like the browesr you are using.

You may also try updating the flash player and check the operations

Change the screen resolution. The video card or video display may not be compatible to the supported video setting of the monitor. Try changing the video resolution to a lower setting such as 1024x768 and bit depth to 32 bit.
