There are few things more frustrating than when you turn on your television to watch your favourite show, only to get a fuzzy or unclear picture. You may be able to watch your show, but you know the lack of clarity will annoy you the entire time. Fortunately, you don't have to be a cable technician to fix the problem. A blurry picture is usually a symptom of two problems--a bad connection or your sharpness settings need to be fixed. You can resolve both issues quickly.

Skill level:


  1. 1

    Turn off the power to your television before you begin working on the cable connections.

  2. 2

    Go behind the TV set and tighten all the coaxial cable connections. You can identify a coaxial cable by its screwlike ends used to connect to the television (usually to the antenna connection outlet). A loose connection will almost certainly make your picture blurry.

    Turn the TV back on, and see if the picture is coming in clearly. If not, move on the Step 4, the next step.

  4. 4

    Turn off the TV again and replace the coaxial cables that connect the cable box to the TV with component cables. Component cables have three colour-coded prongs at each end. Each prong will be either yellow, white, or red. Match the colours on the back of the cable box to the back of the TV. These connectors are less likely to become loose and give you a better picture.

    Turn the TV back on, and see if the picture is clear. If it is not, follow the instructions for adjusting picture sharpness.

  1. 1

    Turn on your TV and go to the its function settings. You can do this either with your remote control or manually.

  2. 2

    Find the sharpness setting and use your TV manual or remote controls to select the desired sharpness level.

  3. 3

    Exit the function setting when your TV is no longer blurry. If problems persist, call your cable provider.
