If your Plasma or LCD TV picture is blurry or fuzzy there are several things that may be causing the problem. It’s worth running through the following list before seeking service. You may find yourself saving the full cost of a TV repair.

• Make sure you are using the appropriate cable box for your TV. If you have a high-definition TV you should also be using a high-def channel box from your cable provider. Watching standard definition channels on a high-def TV can make the picture look distorted and fuzzy.
• Not all cable channels are broadcast in high-definition. When you stretch a standard definition picture to fill the full frame of your wide-screen TV it may look distorted. You can try changing your TV display settings to show standard-def channels at their native resolution. This will create black or gray bands on either side of your picture.
• Ideally all of your video components will be connected to your TV with HDMI cables. Your next best option will be component video cables. If your cable box does not have HDMI capabilities, contact your cable company about upgrading your box to one that does include HDMI.
• Make sure there is no glare on your TV from a window or other strong light source. This can significantly degrade the quality of the image you are watching.
• If your TV has digital noise reduction, try turning that feature on.
• You can adjust your TV’s sharpness and picture modes to see if that improves picture quality.
• Try plugging the power cord into a different electrical outlet and/or surge protector. You may be receiving electrical interference through your power cord.
• Trying moving any nearby electrical devices away from the TV. They may be creating interference that can degrade the picture quality.
