But everything is getting power. I've reconnected everything multiple times with no luck. This is the 2nd time we have paid lots of money for one of these hi-tech tvs which last only a year.
Bring back analog and rabbit ears! I'm done with these modern cheaply made appliances. Same problem with the icemaker on our expensive whirlpool fridge. It is all a ripoff. The controller board has been replaced twice. I've replaced all the HDMI cables 4 times with different brands each time. Software has been reloaded twice. TV has been reset to factory defaults 5 times. Despite all this it still doesn't work. LG has been good about coming out and trying to repair it but we're not getting anywhere.
I've got it on video several times but this is the best footage:. Has anyone else had this problem? Where regardless of what device you have plugged in the TV just loses signal randomly? This time they replaced the controller board AND the power supply.How to fix LG TV says No Signal when Connected to HDMI -- LG TV Displays No Signal Message
The theory was that the power supply was defective and it was damaging the controller board. That appears to have been the case because after replacing the power supply the TV has worked perfectly and has not lost signal once.

This is the most important step in this process. Staying organized can save you hours of frustration. Important: Pay close attention to the TV ports. In and Out mean very different things. At this point, you should have all of your wires plugged into the TV, and your devices laid out on the floor.
Use your color code chart as reference, and connect the correct cables to their respective devices. Important: Write down the Input Number of the Audio receiver where you connect the cable. You will need to reference it later. Insert all cables into their respective devices. Use the color coding notebook from earlier to doucle-check the device colors. Note: These steps may differ slightly by model, but we will show the steps for our most popular platform webOS.
Note: Smart TV owners can use the Device Connector app instead of following these steps if desired find the app in the Launcher bar.
Refer back to the notebook you used in the earlier steps to reference which input will show which device. Note: Some Audio Receivers or Soundbars use different terminology to change inputs. Your remote may have an Input, Function, or Source button these all mean the same thing. Simply connect the drive to any available USB port, and the TV will automatically prompt you to use it.
Note: Bluetooth mice and keyboards are not supported. Some users have had success using the LG Bluetooth Rolly Keyboardbut this is not officially supported. Some TVs may have Headphone Outputs, but this is not common. Note: Some TVs have a 3. This port is the exact size of a headphone jack, but is not designed for headphones.

Built-In Cable or WiFi. Gaming Console. USB Drive. AN-WF Dongle. Streaming Devices. HDMI Video.Determine which connected external device is not sending a signal. Review the steps below based on the type of external device connected to the TV.
The No Signal message indicates a problem with the cable connection or the external device. Check if the TV is on the proper input. Press the Wheel or Enter button, the input that is selected will be displayed briefly on the TV screen. Check if the cable is plugged in securely to both the external device and the TV.
Perform the following steps if the No Signal message remains:. Unplug the power to the external device for 30 seconds. Plug the device back in, and power the device back on. If you're troubleshooting a cable or satellite box, allow time for it to boot up after power is restored. If the No Signal message remains, then access the menu system on the external device to set the resolution to p or higher, preferably i.
HDMI does not allow the use of i. If the TV continues to display the No Signal message, the cable box may be malfunctioning. To verify whether the cable box or the TV is the cause, disconnect the cable box from the TV and connect another external device such as a Blu-ray player, DVD player, or gaming console.
If the No Signal message no longer appears and has been replaced with video from your device, the TV is working correctly. Contact your cable provider to check the cable box. Once the cable box has been tested and working properly, if the No Signal message continues to appear on the TV, the TV may require service.
Check that the laptop is set to output a resolution supported by the TV. A setting of x is recommended to provide the best image quality. If there is still no display, then proceed to the next step. The original HDMI cable may be faulty. If all steps have failed, the TV may require service.

Check that the TV is on the correct input Component. Check that the external device is powered on. Make sure the Red, Green, and Blue cables are routed correctly and inserted securely on both devices. If the No Signal message appears or there is no image, then reboot the external device. Plug the power back in to the external device. Switch the device on. If the No Signal message continues to appear, replace the component cable. If the substitute cable worked for another external device, but with the current connected device the signal continues to fail, then the problem may be with this device.
To verify whether the external device or the TV is not receiving the signal, disconnect the external device from the TV. If the No Signal message no longer appears with the new device, and a video signal appears on the TV, then the TV is working properly. Cable Connection Results. Correct Component Connection.

I love the TV and it's great. Except one thing that I find irritating is a constant AV input popup that keeps reappearing over, and over, and over.
While watching any content from any input, the popup appears. This image is one example of it, inside the Netflix app. WebOS seems to enter some variable loop, displaying several of these popups in sequence.
Often, the number of popups is such, that the TV will freeze trying to show all of them. I can only assume a lot of its CPU is being used to render them. The TV will become unresponsive until all popups disappear. The annoyance may last a couple of minutes, but it happens everytime the TV is turned back on.
From the input configuration screen, I can see the AV input is active. And I can try and remove it from the list of inputs.
Once it's removed, the popups are gone. As a user, I have to consder this a bug. And it's a very irritating one. These popups cover subtitles and seem to show up minutes after the TV is turned on. Please provide a fix with a firmware update or, at least, provide a workaround to make it stop. I've had an LG 47LB for about five months now. There is no such option in the Sky box configuration. Not that I can find. There is an option in the TV settings to control the Sky decoder from the LG universal remote, but that's also disabled.
Also, regarding Keith Flavell's post, Simplink is already turned off. Turning it on or off makes no difference. Nothing else attached but the AV2 pop up repeatedly flashes on screen. Removing it from the launcher stops it until I turn the tv off and back on.
