Problem 4: Remote control.

Phenomenon: After turning off the power button with the remote control, you can't turn on the remote control after a period of time, you can only pull the plug and plug it back in to turn it on, how to solve it?

Solution:Because the remote control of the TV is a Bluetooth device,So after shutting down,TV Bluetooth out of the shutdown stage,So of course it can't be turned on remotely directly。

If the problem is not solved,You can call the official customer service consultation,You can also go to the ZNDS smart TV forum to find the administrator for help,May you successfully solve the problem!

1、The reset button of the LG TV motherboard is easy to short circuit when pressed for a long time, causing the CPU to receive an error signal,It will shut down or restart。 2. Check whether the chain wang LG TV power supply is normal, whether it is broken or the contact is poor. 3. Check whether the LG TV remote control is turned on standby.

Suggested solutions: 1. Remove or replace the reset button. If the TV's indicator light has a button in front of it, remove it as well.

The demolition will not affect the normal use of the shed. 2. If it is abnormal caused by power supply problems, it is good to replace it with a new one. Check whether you have pressed the [Power] button of the TV remote control to turn off the screen display of the TV,Make the TV in [Standby State], you can press the [Power] button of the remote control again to start the screen and return to normal。

3、Press the power button to try,If you turn on the TV normally,It may also be that the remote control battery is dead,You can also change the battery to try,If it still doesn't work,Then you can only ask a professional master to come to the door for maintenance。 4、The TV still does not respond after the above method investigation,It is generally judged that the hardware failure of the TV causes the TV to be unresponsive,Including the failure of the motherboard switch circuit、Screen cable failure、Screen failure、Other component failure, etc.,If there is no problem,It is recommended to contact the after-sales service of the TV for comprehensive testing and warranty of the TV。

It should be the source of the problem in the starting circuit of the TV, generally the starting resistance bai variable value (the resistance value becomes larger du), or.

The starting capacitance is out of capacitance;

The landlord can do an experiment like this:

1. Leave the TV for a period of time (be careful not to unplug the power cord), if it can be turned on smoothly later, then it is the problem of capacitance loss of start-up capacitance;

2. Unplug and unplug the power cord many times to see if it can be opened, if it can be opened, it is the problem that the starting resistance value becomes larger;

The repair cost for such failures is very low.

The LG TV does not light up (i.e. the screen is black.

The general treatment of the following:

1. Check whether the power supply of the TV is turned on, whether the power switch is turned on, turn on the power of the TV, and turn on the switch to solve the problem;

2. Check whether you have pressed the power button of the remote control to turn off the screen of the TV and make the TV in standby mode, you can press the power button again to solve the problem;

3. Check whether the TV detects that there is no signal input and starts the black screen protection, you can first check whether the signal input connection of the TV is unblocked, and then switch between modes by pressing the signal source key of the remote control Labi, such as TV mode, ** mode, HDMI mode, etc.;

4. If there is still a black screen after the method is checked, it is generally judged to be a black screen caused by hardware failures such as the motherboard switch circuit or other component failures and screen failures of the TV, and it is recommended to contact the after-sales service of the TV for comprehensive testing and warranty of the TV.

First of all, you need to check the power strip of your TV.

There is electricity. Minqing: If you have to see if the power cord behind the TV is loose, whether the power switch of the TV is turned on, if you have all of the above, it is estimated that there is a problem with the power strip of the TV.

It depends on the situation,First of all, you have to find a professional to stare at the cause of the failure of the TV,Replace the damaged or faulty electronic components according to the fault situation,Non-professionals can not disassemble electrical objects at will,In case of electric shock。

Maybe it's because the line is broken.,I swept.,So it's not lit.,I think you should find a TV maintenance personnel who specialize in the industry to repair the silver source.,It's probably a few dozen dollars to fix the front stool.。

The reason why it can't be opened——

1. The power supply for LG TV may be faulty.

2. In the event of a short circuit or leakage fault in the circuit, in order to protect the safety, the protection circuit will be started with the connection. Letters.

3. The TV is in standby mode, so it can't be turned on, for example, the user mistakenly presses the [Standby] button of the TV remote control, so that the TV is in standby mode.

Suggested Treatment:

1. You can use a multimeter to check whether the switching power supply has an output to see if the voltage is normal. If the output voltage is abnormal, the main power supply is faulty. You can find a maintenance worker to come and repair it.

2. If it is caused by circuit problems, it is necessary to contact after-sales or maintenance workers to repair the faulty circuit.

3. Generally, the probability of multiple faults occurring at the same time is very small, and it is analyzed and found one by one according to the order of main power supply, line scan, and main channel.

4. If this is the reason, you can press the [Standby] button of the remote control to wake up the TV and return to normal.

5. Use the power button of the remote control (generally red), or press the standby button on the TV (standye), press the channel + -ch+, ch-) without the slippery cherry button, and see if you can turn it on, if you can't turn it on, there is a problem inside the TV, then you need to ask a professional maintenance personnel to come to the door for maintenance, do not repair it at home, it is easy to cause secondary injury.
