HDMI cable/satellite box, BDP, and other devices
Ensure the TV is on the proper input. Verify the connection is secure and retry. Unplug the external component for 30 seconds, disconnect the HDMI cable from the TV and move it to another port, plug the device back in, and change the TV to the new input to see if the problem is resolved. Sometimes, the cable/satellite box may lose the resolution setting. Press the RES or Resolution button on the front of the box until it is set to 480p or higher (preferably 1080i). If this button is not available on the box, press the Info button on your remote. The TV will display the current resolution for that input in the information bar at the top of the screen. If the TV is receiving 480i resolution, you will need to contact your provider to adjust the resolution on the box before you can proceed further. If the above steps don’t resolve the issue, then your TV will need service.
HDMI PC or Laptop
Ensure the TV is on the proper input. Be sure the laptop is set to output a resolution supported by the TV. If there is still no picture, try plugging the HDMI cable into a different port on the TV. Then, swap the TV to the appropriate input.

Be sure the TV is on the correct component input. Make sure the red, green, and blue cables are routed correctly and inserted securely on both devices. Unplug the external device for 30 seconds and then restore power. Check if a picture is displayed and you can hear sound. If not, try an alternate component cable or alternate set of ports.
A/V Composite
Be sure the TV is set on the AV input. Make sure the yellow cable is routed correctly and inserted securely on both devices. Unplug the external device for 30 seconds and then restore power. Is the issue resolved? If not, try another AV cable or other set of ports.

LG TV takes a long time to turn on
