Lg Oled Tv Screen Goes Black Few Seconds
I have a 55″ HDTV. The TV screen periodically goes black at random times and appears to be off. The sound still works and the power light is still illuminated when the TV screen turns black. Is this called the "Black screen of death"? I have checked all HDMI and COAX cables on back. I have switched the inputs to BLU-RAY and CABLE and the screen remains black. I have no issues with cables or inputs. I have to turn the TV off for 5 minutes and turn back on to fix the problem each time. My TV is out of warranty. How do I fix this?
TV Screen Goes Black Randomly – Power Light Still On
NOTE: Some troubleshooting steps may be different from your (Samsung, SONY, LG, Hisense, TCL, VIZIO) TV or remote control but generally will work the same to fix the problem.
FIX TV SCREEN THAT RANDOMLY GOES BLACK
1. Check that POWER SAVER/ENERGY SAVE MODE is set to OFF.
Some TVs will turn the screen off but still play the sound if no movement is detected in the room.
2. Was SLEEP TIMER mistakenly turned ON? – Turn OFF.
Sleep timer can sometimes be pressed on the remote and will turn OFF the TV.
3. Check that STORE MODE/DEMO MODE is not turned ON.
Store mode or demo mode is a factory setting to be used for a display or demo.
4. Use a different HDMI port for the component you are using.
Unplug the HDMI from one input, and plug into a different input to test if port is bad.

5. Connect a different component to the TV or the same component to a another TV.
The component being used (Ex. Blu-Ray/CABLE BOX) may be causing the black screen issue.
6. Turn the component (Ex. Blu-Ray/CABLE BOX) you are using OFF and then back ON.
The component you are using may have a temporary fault and needs to be reset.
7. Hidden fault within HDMI cable – Replace with new cable.
Replace the HDMI cable as it may have a short or other defect which causes the black screen issue.

Go into MENU and find FACTORY RESET – You will lose any picture settings you may have saved.

Repair A TV That Still Shows Black Screen
If the issue of the TV showing a black screen randomly is still not resolved, you can try to claim warranty service or fix the TV yourself. 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.
