I have a 75-inch TV. The left side has a dimming in the backlight, but you can still watch programs on it. The sound is normal. The internal receiver is working. It has LG Smart system. It comes with two remotes, one is a smart mouse and the other is normal, both are new. The device is clean, the only issue is the backlight on the left side. Selling it for a good price for whoever is interested.
