What to do if my LG 55LA7900 has no image and sound?
If your LG LED TV shows no image and produces no sound, first ensure the TV is turned on. Then, verify that the power cord is securely connected to a wall outlet. Finally, test the wall outlet by plugging in other devices to check for any issues with the power supply.
Why does my LG 55LA7900 LED TV turn off suddenly?
If your LG LED TV turns off suddenly, examine the power control settings to ensure the power supply isn't being interrupted. Also, check the Time settings to see if the Auto sleep feature is enabled. If the TV is on but receives no signal, it will automatically turn off after 15 minutes of inactivity.
