Rated 2 out of 5 by from 2 star because its not a Smart TV anymore TV quality is great. The only thing is that its suppose to be a Google TV and since google change to Android TV they did not send the update to the TV. They can At less update the TV to Android TV OS or there own WebOS. The Remote needs improvements

Rated 5 out of 5 by from Amazing TV I bought this TV two years ago in February and loved it from day one. It has amazing features plus great picture quality. I definitely would recommend anyone looking for a cheaper TV to get this one. Since it is discontinued if you can find it used get it! I now have this TV in my room and got a new LG tv for my room. Will never give this TV away.

What Universal Remote control could be used for this TV? The stock OEM Remote control is very expensive. Would the LG Remote "AKB" be a solution? If not, could you please address this issue by providing a lengthy list of universal remotes? Thank you.

Asked by: DonDaDa
We regret the inconvenience you have experienced in this matter. The letters AKB are the start of many remote control part numbers, not all of which are interchangeable with each other. This TV is compatible with the part numbers AGF76820701 and the AKB73736002. We have no information available about Universal Remote Controls or their compatibility, however, these 2 controllers have a Bluetooth component for the on-screen pointer feature, which will not be found on most Universal controllers.

Need to know how to reset remote to use arrow on gesture button?

Asked by: Dirtyd
When attempting to RE-REGISTER the remote control, begin by pressing and holding the BACK button for 3 seconds. Once the RESET is complete, the light on the pointer will blink. Press the POINTER button to pair the controller with the TV once again. Please be certain that no other Bluetooth devices are active in the vicinity of the television for operational convenience.

Asked by: Marky713
The LG 55" Class Cinema 3D 1080p 120 Hz LED TV with Google TV (54.6" diagonal), Model # 55GA6450 came with the LG Magic Remote Qwerty, Model # AN-MR400Q as an included accessory with which you could input alphabet characters on the TV screen.
