2, continuous switch app, will let the TV change card

A: Due to limitations of the Android system, after launching multiple applications, multiple background processes will occupy system resources, which will slow down the operating system, such as Android phones on the market. For this, it is recommended that you download some cleanup tool applications to clean up the system cache.

Smart TV boot problem

1. The smart TV emits a crispy “click” sound after watching or turning off the power.

A: The smart TV is a cold-to-hot process in watching. After the power is turned off, the machine is a hot-to-cold process. At this time, the machine suffers from thermal expansion and contraction, which causes the chassis to rub off. The normal phenomenon, although it will not affect the viewing experience, shows that the work is not precise enough. Not all smart TVs will make such sounds.

A: The above three kinds of channel change methods are all normal phenomena. It is a setting method of the machine itself. If there is “Turntable standstill: ON/OFF” in the operation “Menu” option, you can change this item.

In another case, the machine is set to be still at the change screen, but some channels are black when switching channels. This is also a normal phenomenon. This is mainly due to the non-standard signals, causing the synchronous recognition of the circuit signals to track errors, and recovering in a short time. Is a normal phenomenon

2, there is a short, fat phenomenon

A: This phenomenon is normal. It is because China’s TV programs are currently in 4:3 format. When a 4:3 format signal is received on a 16:9 screen TV, the 16:9 screen TV will widen the 4:3 signal around. , so the image will look short and fat.

If you are not accustomed to adjust the screen ratio to other modes. The 16:9 screen is the development trend of digital TV in the future. It is not recommended to watch in the 4:3 mode for a long time on the left and right screens, which may cause uneven brightness in the middle and on both sides of the screen.

3, smart TV images have snowflakes
