Rated 3 out of 5 by from Was a great TV till it wasn’t Only downside was that it only lasted 14 months! Right after the warranty expired we had a bad storm with lightning and the electricity went out which afterwards the tv screen was blacked out but it still had sound. I then went to Best Buy to find out what I could do about repairing it. I was told that it would cost me more money to fix it than if I just bought a new one. I did end up buying a new one but this has left me a bit angry that it didn’t last longer, and even though I had it plugged into a surge protector it failed only lasted right past the warranty plus I don’t understand how they knew that it could not be repaired by telling them what happened.But the salesman was understanding and he at least gave me a extra good deal on my new Ultra HD TV which I am very pleased with.

Rated 2 out of 5 by from Clarity and Color is good but it is not crystal. Clarity and Color is good but it is not crystal clear. I have had problems with the intermittent power on and off of TV Model 42LD450. I have issues something on the sound cause it wobbles when it is loud. Overall it is fine.

How do I hook up a blue headset  there seems to be no output connection on my 39lb5800-ug tv

Asked by: Bob70
Hi Bob70. The LG 39" Class (38.5" Diagonal) 1080p Smart LED TV, Model # 39LB5800 does not have a headphone jack for connecting wired headphones to. It has an Optical Digital Audio Output in the back for connecting to external receivers, Sound Bars and Home Theater Systems that can also be used with a Digital/Analog Converter to connect to the transmitting tower for a pair of infrared wireless headphones. Bluetooth Headsets do not require any audio output connection since they can be paired with the TV so you can stream the audio wirelessly via Bluetooth. This TV has been tested for compatibility with our LG Tone Series Bluetooth Headsets (Models: HBS-700, HBS-730, HBS-800 and BTS1 only) and other brands are not guaranteed to work. This TV supports the LG Wireless Sound Sync so the aforementioned headsets can be paired with the TV by following the path, Home > Setting > Advanced Setting > Sound > Sound Out > LG Sound Sync (wireless) or LG Sound Sync / Bluetooth. You will also need the LG Wi-Fi® Bluetooth® USB Dongle for Select 2014 LG TVs, Model # AN-WF500...^IFV
