A defective TV can be annoying. Of course, the owner can perform simple repairs on his own, but only if the problem is general in nature. Only specialists on this site can carry out more complex TV repairs. Problems specific to LCD, Plasma or CRT TVs may also require specialist attention. Below we will tell you about the most common problems that arise with TVs, and how to solve them.
The most common TV malfunctions
A bad picture can ruin a good TV show or movie. You can solve the problem yourself and avoid the cost. Rear-projection TVs often require good cleaning. Internal cleaning of dust or debris may result in a rear-projection TV displaying an unclear picture or otherwise degrading its quality. This can be fixed by opening the TV and cleaning the three colored lights inside. Before removing the back cover, turn off the device and let it cool down. Use only microfiber cloth and lens cleaner to clean the lamps. Ammonia-based cleaners, usually for other lamps, can discolor the mirror on your TV.
Rear-projection TVs use lamps that typically last around 1000 hours. If the value of the image has dropped significantly - for example, if the image is dim or parts of the display are dark - you may need to replace them.
Other electronic devices may interfere with the TV. For example, halogen bulbs and space heaters can interfere with radio frequencies. It appears static on the screen and may cause poor video quality. You need to disable the sources of intrusion to fix the problem. If static electricity remains, plug the household appliances or TV into separate outlets.
Poor picture quality is sometimes caused by the signal being received by the TV. It is recommended that you activate the electronic noise canceling function to compensate for a poor broadcast or cable TV signal. This feature will cancel ghosting that can appear on the monitor, both static and full screen. This is best combined with the TV's automatic convergence feature, which can remove monochrome ghosting.
Even the best equipment sometimes stops working or doesn't make an impression. There are things you can do to test this if your subwoofer or home theater sound system fails or stops working.
You need to find and update the troubleshooting guide in the user guide for your home theater system. First of all, you need to check the cables, but do not pinch or pinch them. This can break the wires inside. The cable to be pinched must be replaced and the sound system connected to test the subwoofer.
Electricity is movement, and although the vibrations may be slight, the cables may loosen over time. First, we check to see if there is an incredibly high level of distortion or low frequencies in the subwoofer settings. A large amount of reverberation can distort the sound and even damage the speaker. It is worth trying to set a lower bass level on the speaker cabinet before you lose the buzzing sound if you hear any distortion or vibration when using the subwoofer.
If the subwoofer is silent, the first step is to check the settings on the receiver. If the speaker is not properly sized, the subwoofer and sound system will not communicate properly with each other, resulting in the subwoofer not responding. When you find that the speaker size is set too high, you need to resize it to a smaller size and check if the audio problems are resolved.
The more sophisticated TVs get, the more delicate they become, and malfunctions can range from simple color and brightness issues to serious burned-out capacitor issues. Most common TV problems can be solved by going to the settings menu or by turning the TV off and on again. If this looks like a problem that can be solved by changing the settings in the TV menu, it is worth trying to do it yourself, but if it looks like something more serious, we strongly recommend that you do not try to repair the device at home, but contact the professionals.
