Picture problems can manifest themselves many different ways on modern TVs. You may see pixelization or static on the screen, you may hear audio distortion, channels may flash intermittently or not show at all or you may see blurriness, striations, or banding across the TV screen. Complicating matters further is the face that there can be many causes of these symptoms, which can make troubleshooting and resolving them more difficult. With some basic know-how and a small time investment, however, you can diagnose and resolve a blurry picture on your own, without need to consult any outside help.
Instructions
1. Reset the device you are trying to watch by unplugging its power cord for 30 seconds and plugging it back in. If you see the blurry picture on the cable box, for example, unplug the cable box's power cord and allow it to reboot after plugging the power cord back in. Check the picture for any improvements.
2. Check the audio/video connection cables that attach the device you are trying to watch to the Zenith's audio/video input ports. Also examine the audio/video cables that attach the cable box to the TV and see if any have come loose. Replug any cables that may have come loose and replace any badly damaged cables. If you think the cables may be malfunctioning, you can test the issue by temporarily plugging in another set of audio/video cables and checking for any improvement.
3. Scan through all your cable channels and all of the Zenith's input channels to determine the scope of the issue. If the blurry screen is only seen on cable channels, your digital cable box or your provider may be source of the problem and you will need to report the issue to them. If all the input channels show the same blurriness, the Zenith will likely need to be serviced for a failure of its picture components.
