Why LCD TVs are hard to turn on

Life is getting richer and richer. With the popularity of TV, people can watch the world through a small screen. It provides convenience to people's life. Even if you don't leave your home, you can enjoy the wonderful world outside. You can also watch some TV series, movies, etc. to pass the time. However, there can be problems with the TV after using it for a long time. For example, it may be hard to turn on. It doesn't turn on for a long time, and sometimes it won't even turn on. So, what's wrong with it?

The LCD TV in your home is made up of two parts. One part is the display and the other part is the receiver. The receiver is connected to the signal source. If you want to watch TV, you must first, turn on the power button on top of the receiver, then press the button on top of the monitor. Then bring the remote control to the monitor and press the power button. After the red light on the monitor flashes three times, the TV will appear. Does it feel like a lot of trouble?

For 7 inch touch screen, we have different models for customers choice such as 800*480, 1024*600, 800*1280, normal brightness and high brightness.

In fact, if it is a general LCD TV. It's hard to turn on, there may be an internal problem. First of all, we have to measure whether the voltage is normal. Because the level of voltage will also affect the speed of the boot. Then we have to test whether there is a signal. Because some LCD TV it is connected to the signal source is the antenna pot. The signal of the antenna pot, it changes with the weather. When the weather is bad, then it may not have a signal and the power on will be slow.

If the problem occurs inside the TV. If you are not a professional, then it is difficult to find out the cause. So I still suggest that if there is no problem with the power supply, then you can call a professional to repair it.

It is also hard to turn on the TV at low temperature. Because of the low temperature, its resistance is not easy to start. Secondly, if the resistance becomes large, then there will also be a poor contact condition. This time also makes the whole circuit difficult and the power on becomes slow.

Another reason could be that the capacitor capacity of the TV is very small. If after several power-ups, it still cannot fill the capacitor capacity, then it will not give the power-on command.
