it turns on, but when I select start, by pressing Ok, nothing happens

I apologize for the inconvenience you’re experiencing with your LG TV 55HU6150. Let’s troubleshoot this issue together. Here are some steps you can try:

1. Check the Input Source:
   • Sometimes, the TV might be on, but it appears off due to an incorrect input source. Ensure that you’ve selected the correct input (e.g., HDMI, cable box, Blu-Ray player) using the remote control.
   • Press the Source/Input button on your remote to cycle through the available input options. Make sure it’s set to the source you intend to use.
2. Power Cycle the TV:
   • Unplug the TV from the wall socket.
   • Wait for 45 to 60 seconds.
   • Plug it back in and turn it on using the physical button under the TV.
   • Check if it responds when you select “Start” by pressing OK.
3. Disable Quick Start Feature (if applicable):
   • Press the Home button on your LG TV remote.
   • Go to Settings.
   • Navigate to the General option.
   • Select Quick Start+ and turn it off.
   • Verify if the issue persists.
4. Check Power On Timer Settings:
   • If your TV is turning on automatically, it might be due to timer settings.
   • Go to the TV’s settings menu and ensure that the Power On Timer option is turned off.
5. Inspect the Remote Control:
   • If the issue persists, check the remote control.
   • Remove the batteries from the remote and press the power button for 20 seconds.
   • Reinsert the batteries and try again.
6. Physical Button Under the TV:
   • If the remote isn’t working, use the physical button located under the TV to navigate and select options.

If none of these steps resolve the issue, consider seeking professional assistance or contacting LG customer support for further guidance.
