If you’re still having trouble with your LG TV’s no signal problem, it might be time to consider professional repair. You can easily find a local TV repair service that specializes in fixing LG TVs. Before committing to repair, make sure to evaluate the cost of repair versus replacement to see which option is more cost-effective for you. Here’s a step-by-step guide on how to update an LG TV via USB: Step 1: Visit the LG support page. Step 2: Enter your TV model number on the search bar. Step 3: Tap your model number from the results. Step 4: Download the zip file of the latest firmware update. Step 5: Extract the file. Test if the Monitor is Properly Powered. To help diagnose where the problem is, you should test to make sure that your monitor itself is not the problem. LG Monitors use energy-saving technology, so if there’s no signal, they may appear to be off – but there should be an indicator light somewhere on the model. Check to see if it’s powered. Right-click the Start button, select Settings > Update & Security > Troubleshoot. Select Hardware and Devices under Find and fix other problems. Click Run the troubleshooter. If prompted, click Yes or enter the administrator password. Follow the on-screen instructions. .
