Screen goes black every so often.

My TV screen will turn on and then go black every so often. Most of the time it works fine but sometimes it will go black or half the screen will be really dark. If I turn it off and back on it will start working again. Sometimes it takes 3-4 times of turning on and off before the picture works again. Also when it does go black the sound still works perfectly. Is it the back lights or main board or what? It’s an LG 60UH7700 TV. Thanks for any information you all can give me.

So sorry that you have encountered such an issue. But there are many methods that you can try.

1. Check that POWER SAVER/ENERGY SAVE MODE is set to OFF.

2. Turn off SLEEP TIMER.

3. Check that STORE MODE/DEMO MODE is not turned ON.

4. Use a different HDMI port for the component you are using.

5. Connect a different component to the TV or the same component to a another TV.

6. Turn the component (Ex. Blu-Ray/CABLE BOX) you are using OFF and then back ON.

7. Hidden fault within HDMI cable – Replace with new cable.

8. Unplug the TV for 5 minutes to attempt a reset.

9. Factory reset the TV to resolve the issue.

10. Download new software/firmware update.

In many instances this issue is caused by a bad driver board, LEDs, or possibly a faulty T-Con board in the TV. It may also be an issue with bulging capacitors or a loose cable or ribbon connector. You will need to take the TV apart and diagnose the issue. We do not recommend you do the repair yourself unless you know exactly what you are doing.

If the issue of the TV showing a black screen is still not resolved, you can try to claim warranty service or fix the TV yourself.
