Here are the steps to program your OneForAll URC 3050B00 remote to control your LG smart TV:
Turn on your LG smart TV. Press and hold the "TV" button on your OneForAll remote until the LED light on the remote turns on and stays on. Enter the 4-digit code for LG TVs. The most common codes for LG TVs are 0030, 0056, 0178, 1265, and 1398, but you can also find a complete list of codes on the OneForAll website or in the manual that came with your remote. Press the "Power" button on the OneForAll remote. If the TV turns off, the code has been successfully entered. If the TV does not turn off, repeat steps 2-4 with a different code until you find the correct one. If none of the codes work, you can also try the code search function on your OneForAll remote to automatically find the correct code:
Turn on your LG smart TV. Press and hold the "TV" button on your OneForAll remote until the LED light on the remote turns on and stays on. Press and hold the "SET" button on the remote until the LED light blinks twice. Press the "9" button on the remote. The LED light should blink twice again. Point the remote at your TV and press the "Power" button repeatedly until the TV turns off. Press the "OK" button on the OneForAll remote to save the code. I hope this helps you program your OneForAll remote to control your LG smart TV!
verify that you have no image on all inputs. If it remains dark, unplug it and push the power button for about one minute, then plug it back in. See if that resets your TV.
If it remains dark, use a flashlight and angle it against the screen with the TV at a station where you can hear the sound See if you can make out shadows or shapes. If you do, then it is your backlight that has failed.
Hello, either the power supply is failing to power up the LED's or the LED strips in the screen have failed, a common issue with these sets. Power supply part # is EAY62169701. LED strips are only available as a complete screen assembly from LG....thanks
