At present, some old-fashioned antennas can still receive analog TV signals of 1 to 3, but the general signal quality is very poor, so antennas with amplifiers are needed to receive them stably. Most areas have launched wireless digital greetings for rural areas, which are only equipped with special set-top boxes and can only be watched for pay.

Digital TV maintenance:

1, all parameters are recommended by the brand. This is the result of many tests by manufacturers, which can reduce the loss of LCD TV to a lower level. For example, an LCD TV with adjustable resolution can be used at the recommended resolution to present a better picture, which is actually a screen saver.

2. Avoid scratching and hitting the LCD screen. The LCD screen is very weak. Direct contact or impact can easily damage small lines and equipment. In particular, children at home like to point their fingers at the screen, which is quite harmful to LCD TVs. In addition, don't let the LCD TV screen stand still for a long time.
