Dear maintenance masters, please note that when the light strip circuit fails, the master will generally use a lighting device (light strip tester) to repair it. Please check the positive and negative poles carefully before testing. The lighting devices currently on the market have the hidden danger of burning out the lamp beads, and may fail to light up (the lamp beads break down and short-circuit), light up slowly, etc. |

| Fault phenomenon | Cause of Failure | Solution |
| Light is not on | Constant current board damaged | Replace the original constant current board |
| Light strip circuit open | Use a spotter (light bar tester) to test one by one to find out the failure point | |
| Positive and negative poles of light strips are reversed | According to the positive and negative poles of the light bar | |
| Using the wrong light strip | Use a lamp lighter (light strip tester) to judge whether the voltage of the original lamp bead is the same as that of the light strip you are replacing now | |
|
Light flashes (flashes once and then goes out) |
Constant current board protection | Generally the protection is current protection, you can cancel the protection first, after normal, then technology to change the constant current board |
| Constant current board damaged | Replace the original constant current board | |
| The operating voltage of the light strip is higher than the normal output voltage of the constant current board | 1. Reduce the number of lamps 2. Improve the constant current board to increase the output voltage. (Requires good electronic knowledge) |
|
| Light flashing (strobe) | Constant current board protection | Generally the protection is current protection, you can cancel the protection first, after normal, then technology to change the constant current board |
| Constant current board damaged | Replace the original constant current board | |
| Burning lamp beads(starting up) | The output voltage of the constant current board is higher than the maximum operating voltage of the light strip | 1. First of all, it should be clear how much voltage of the lamp bead of the original machine? 3 volts or 6 volts? 2. To ensure that the number of lamp beads and the number of original machine lamps and almost the same 3. To be clear that the original lamp is connected in series or parallel 4. If the first to the third are right, it is recommended that the master to increase the number of lights |
| Constant current board failure | Replace the original constant current board | |
| Burned lamp beads (used for a while to burn) | Constant current board output current is higher than the rated current of the lamp beads | The constant current board needs technical modification, and the maintenance master needs to find the part of the constant current board that controls the current and remove the resistor. You can also take a photo of the constant current board and send it to the customer service. We provide free technical modification plans. The current of the 3V 1W lamp bead cannot exceed 0.3A, the current of the 3V 2W lamp bead cannot exceed 0.6A, the current of the 6V 1W lamp bead cannot exceed 0.15A, and the current of the 6V 2W lamp bead cannot exceed 0.24A. |

When an LG TV screen goes black, there are several steps you can take to troubleshoot and potentially fix the issue:
1. Check Power and Connections:
● Ensure the TV is properly plugged in and the power outlet is working.
● Check all cables (HDMI, power, etc.) to make sure they are securely connected.
● Try using a different power outlet or power strip.
2. Restart the TV:
● Unplug the TV from the power outlet.
● Wait for at least 30 seconds.
● Plug the TV back in and turn it on.
3. Check for External Device Issues:
● Disconnect all external devices (cable box, gaming console, etc.) and see if the TV screen comes back on.
● If it does, reconnect the devices one by one to identify the problematic one.
4. Update Firmware:
● If the TV turns on, check for firmware updates in the settings menu.
● Install any available updates, as these can sometimes resolve screen issues.
5. Reset the TV:
● Go to the TV's settings menu.
● Find the option to perform a factory reset (this may be under "General" or "System" settings).
● Note that this will erase all settings and data on the TV.
6. Check Backlight:
● Shine a flashlight on the screen when the TV is on. If you see a faint image, the backlight might be broken. This often requires professional repair.
7. Inspect for Physical Damage:
● Look for any visible damage to the screen or casing of the TV that might indicate a hardware issue.
8. Contact Support:
●If none of the above steps work, contact LG customer support for assistance.
●If the TV is still under warranty, they may offer repair or replacement options.
Each model may have slightly different troubleshooting steps, so referring to your TV's user manual can provide specific instructions for your model.
