No modern home entertainment system is complete without the presence of a good, fully functional television set. Newly developed technologies and expanded programming have driven consumers to purchase television sets with more features and at relatively higher costs. However, just like any other electronic device, even televisions with the latest technologies can encounter problems while running. In this article, we list down some of the most common reasons for TV malfunctions. In any case, it is highly recommended that repairs should be made by certified technicians.
Blurred Picture
One of the most common malfunctions is a blurred picture. This may be caused by problems in the coaxial cable connecting the TV to the antenna. The wiring may be flawed, or it may have a loose fitting. An easy way to determine if this is the reason for the blurry picture is to test the display on another television. Once the cause is established, the cable can be easily replaced. It is not only inexpensive but is also available from most electronics shops.Blotched Display
Another common malfunction is the appearance of blotches of colour, which may be particularly visible around the edges of the screen. This can happen when the television set is placed near a magnet and as a result, the screen becomes magnetised. While most TV sets do contain internal circuitry that helps the screen to de-magnetize, the circuitry may itself be non-operational. To demagnetize it manually, a strong magnetic coil should be placed and moved near the screen in a circular motion until the blotches gradually disappear.Static Noise Emission
Replacing a television speaker which emits static noise can be simple but requires extreme caution. You have to remove the back cover of the television set, which exposes the high-voltage lead that runs into the top part of the picture tube. Even if the television is unplugged, the tube can shock a person, therefore do not touch it in any way. A replacement speaker, of equal impedance to the original one will also be needed. Again, these are available from most electronics shops. To replace the speaker, the top cover must be removed carefully, avoiding damaging any internal wiring. The faulty speaker should then be identified and replaced with the newer one.Random Shutdowns
If the television set shuts down randomly, there could be a high possibility of overheating. The ventilation shafts of the TV should be cleaned and any obstacles are removed. Use a small vacuum attachment to remove any dust that has built up there. This should successfully prevent your television from randomly shutting off again.These methods should solve most of the problems of any malfunctioning television set. For other, more complicated case, it is strongly recommended that the TV be taken to a certified and qualified technician, since it may not be possible to accurately determine the cause of the problem and make repairs. Professionals who are experts in this field can help you not only to save costs and time but also avoid any possible damage to your device.
