Adjusting sound and picture settings will remedy some TV problems.
Televisions can suffer from a range of issues that cause interference with sound and image quality. Some of these problems are closely linked to the kind of technology used in a specific set. Rear projection televisions, for instance, can suffer from overheating if not properly maintained. This causes the device to switch itself off to prevent damage. Some plasma sets experience "dead pixels," where tiny segments of the screen become fixed in color. These issues often require the help of a professional. However, performing some basic checks and adjustments can resolve many TV problems.
Instructions
Cables
1. Check the coaxial cable that runs from your TV to your cable box, if images appear unstable or fuzzy. A loosely-fitted coaxial cable can lead to both sound and image interference. Twist the metal tip of the copper cable that fits into the rear of your TV. Making tiny alterations to the position of the tip can yield significant improvements to sound and picture quality.
2. Examine the cable for any dents or tears perhaps weakening the transmission signal. Purchase a new cable from an electrical store, if damage is apparent.
3. Make sure any HDMI cables that connect to your TV are securely fitted and plugged in the right outlets. These cables are color coded to match the outlets on many TV sets.
Poor Picture
4. Press the "Menu" button on your remote control if on-screen images lack clarity or have poor color balance. Select the "Picture Settings" option from the on-screen display.
5. Adjust "Color," "Brightness" and "Contrast" levels with the up and down arrows on your remote control. (Some sets have + and - buttons instead.) Altering these settings can yield significant improvements to image quality.
6. Reset your television to its original factory settings, if problems persist. Consult your user manual for specific instructions, as different brands have different ways of resetting.
Audio Problems
7. Push the "Audio" button on your remote control if audio levels are too low or completely inaudible, even when turned up high. Select "Stereo" from the on-screen options, if not pre-selected. Select "Speaker Balance" from the on-screen display.
8. Adjust the balance via the up and down arrows. Position the bold vertical line around the middle of the left and right speakers. If the indicator is pushed too far to either side, your set may experience diminished volume.
9. Check the sound settings on any gaming consoles, DVD players or surround sound systems connected to your TV. These devices have their own audio volume that can inhibit the performance of your TV, if not correctly set. Increase the volume by selecting "Audio" from the on-screen menu and using the + and - / up and down arrows on the remote control of the external device.
