There is no other way.

This is a common occurrence with LG TV.

It may be caused by the defect of the lock switch in the TV electromechanical, which is specifically introduced below:

1. Possible causes:

The switch circuit of the TV is soldered or damp, resulting in poor contact, resulting in frequent automatic start-up;

The high-voltage instability of the motherboard circuit of the TV leads to frequent automatic turning on and off;

If it is a problem caused by the hardware failure of the TV, it is recommended to contact the after-sales service of the TV for testing and warranty.

2. Solution:

Turn off the power and unplug the power cord. (Be careful not to touch the high-pressure plate). Flat-mounted TV, mainly to protect the surface of the LCD. Unscrew the back cover and open the back cover of the TV with all the screws;

LG's LCD TV will automatically turn off after a while, what's the problem???

Hello, the reasons for the automatic shutdown of LCD TV are as follows: 1. The power supply system is unstable, which can also cause the occurrence of automatic shutdown failure, and you can consider configuring a UPS backup power supply with voltage stabilization function. 2.

Fault phenomenon: After the LCD TV is turned on with the curtain drawn, the picture and sound appear, and then the screen is turned off. Repeat the above phenomenon after rebooting with the remote control.

3.Fault phenomenon: It will automatically shut down after watching for a few minutes, and it can be turned on with remote control when it is turned off, and it will be automatically turned off after it is turned on.

Very often. 4. Then use the elimination method to check the memory, graphics card, CPU, CPU fan, motherboard, etc. 5. There may be a problem with the BIOS settings, enter the BIOS to restore the default settings or take out the battery of the motherboard, reverse the buckle discharge, and wait for 5 minutes to reverse install it.

Purpose: To restore the default values of the BIOS settings and eliminate the automatic reboot or shutdown of the BIOS cooling presets. 6. Then check the power supply, the power supply quality is poor, aging or the power is too small, can not meet the power supply needs of the computer accessories, you can replace the high-power and high-quality power supply, if troubleshooting, it is the automatic shutdown fault caused by the power supply.

Second, the switch circuit of the TV is soldered or damp and causes poor contact, resulting in automatic start-up. Thirdly, the high-voltage instability of the motherboard circuit of the TV leads to frequent automatic start-up. You can try to power off and reconnect and restart first, and then overhaul if it fails.

The case applies to lgoled65cxpca.

<> LG TV automatically turns on the white screen, generally the automatic start is because the standby button of the TV remote control is shorted or not reset after being pressed, the TV switch circuit is soldered, the contact is poor due to moisture, the high-voltage instability of the TV motherboard circuit, and the hardware failure of the TV is simply taken for reasons. The white screen is trembling because the power supply circuit on the driver board to the screen signal is abnormal, but the backlight is working normally, and it looks like a white screen.

This case is available for LG OLED65C9PCA TVs.
