Matters needing attention in the use of Xiaomi TV

1, plug in the power plug before turning on the power switch. You can't switch the TV by plugging and unplugging the power plug, because the current may be very large at the moment of plugging and unplugging the power plug, and such a large current directly output to the TV may cause chip breakdown. In addition, it is not advisable to switch the TV on and off frequently, and do not adjust various buttons at will.

2. The color, volume and contrast of large-screen color TV should be properly adjusted, so that the viewing effect can be better, energy can be saved and the service life of TV can be prolonged.

3. When using large-screen color TV, don't cover it with plastic sheets or cloth covers. Don't put foam on the bottom. In order not to affect the ventilation and heat dissipation of color TV, anti-static cloth covers should be used when necessary.

4. Don't move and shake the TV when watching the program normally, and turn it off directly to avoid damaging the TV. No matter from which angle, the TV set should be protected from sunlight to avoid aging of components or overheating of the TV set.

5. When watching TV, you can turn on a small light to relieve eye fatigue, but don't turn on fluorescent light to avoid disturbing images and sounds. The best effect is that the height of the TV is flush with the eyes of the viewer, and the distance between the TV and the viewer should be about 3 meters.

6. Watching TV in summer should not be too long, generally not more than 3 hours, because the current flat-panel TV is very thin, and the internal heat dissipation is not necessarily good. Therefore, we should pay attention to prevent the TV from overheating, otherwise it will easily lead to premature aging of TV components. Don't turn on the TV set brought back from outdoors in winter, but leave it for about 2 hours to make the temperature of the machine consistent with the room temperature before using it to prevent condensation inside the machine.

7. After watching TV programs, it is best not to use the remote control to turn it off, but to turn off the power on the TV. Because the remote control is used to turn off the TV, the TV is in standby state, and there is still current flowing inside. At present, all TVs indicate that the standby power is very small, but the long-term electrification of the internal components of the TV may cause premature aging, which is also unreasonable for energy saving.

8. In thunderstorm weather, it is best to turn off the TV and unplug the antenna and power plug to prevent lightning damage to the TV. If there is an outdoor antenna, properly ground the lightning rod.

9. Try to separate the TV and refrigerator in the two rooms. If it is placed in the room, it is necessary to open the distance and connect two power junction boxes respectively.

10. Unplug the power plug before cleaning the LCD screen. Wipe the display and power supply with a clean soft cloth. Do not use any gasoline, alcohol, benzene organic liquid or aerosol cleaner. In particular, water is also a big killer to the screen.
