Rated 3 out of 5 by from Good picture , features but short life Pleased with picture and features of product but failed in less than four years

Rated 1 out of 5 by from Flickering on and off We have had this TV just one month shy of 2 years with absolutely no complaints. A couple of months ago it developed a white spot leading me to think one of the LEDs fell off. My husband could live with that. This morning it started flickering on and off and is completely unwatchable. I'm researching now to purchase another brand.

Rated 1 out of 5 by from Back lighting strips ?? I've only had the TV for 3 years, The manufacturer stamp says September 2014. I bought it December 2014. Now the screen is flashing on and off. When looking for answers, I found that it's the back lighting strips. Very disappointed. Here it is Christmas time 2017 and NO TV. This sucks. Tried the "geeks" where I bought it and they said they can't get parts. I called LG directly and they said yes there's parts, but now I have to pay for a tech. to come and repair.

Rated 5 out of 5 by from Best Value Ever I have owned this unit for several years now, and cannot state just how happy I have been with this TV. Bought this as a replacement to another unit that failed just after the warranty expired. Great features and picture is excellent.

Rated 4 out of 5 by from A nice , mid range T.V. I have had my TV for about 6 months. I really like it. This is my first smart TV. Still learning how to use everything. Sound is just OK. I hooked my TV up to a sound bar which makes all the difference in the world.

Rated 1 out of 5 by from Horrible TV I bought this tv 2 1/2 years ago and some LED lights burnt out, replaced those and bought a new power supply and now I have verical lines on half the screen. I don't think it's worth it to spend any more money to try to fix it, so I will throw it in the garbage and buy a new TV and it won't be an LG.

Rated 3 out of 5 by from Did not last long I'm not sure why I received an email to review a TV I purchased almost 7 years ago. I really loved the TV until one day the screen was scrambled and it had to warm up to work. I looked on the web and found the TV to be faulty some bad solder connections. It warms up fairly quick in the summer months but with these north east winters it takes much longer.

Rated 5 out of 5 by from Best television picture I have ever owned or seen I bought this television after shopping all over town and on line and found it to be the best picture and features of all that I have or talked with salespersons about. I am hard of hearing having lost it in Korea and my advanced age makes it hard to use a phone or hear the televison without my hearing aids. The only suggestion would be to put a control so the bass and treble could be adjusted. I got a great buy and am happy with my LG television.

Rated 1 out of 5 by from Wont Turn On We have had this TV for 1 year, 8 mos and now it wont turn on. Very frustrating when you spend the money on a nice TV and it doesn't even last 2 years. LG will definitely not be first on our list when looking for a new TV.

Rated 1 out of 5 by from Bad circuit boards LG is having a circuit board problem. Stay away from all of them. My 5600 has a bad board and they stopped making them so I can't fix mine.

Rated 2 out of 5 by from HDMI ports stopped working I bought this tv a year ago and I hardly used it. A month after the one year warranty ended the HDMI ports stopped working.

Rated 4 out of 5 by from Sound is poor Great TV overall, picture is good however at the bottom the screen looks cheaply built into frame as I can actually move it
Date published: 2015-11-04
Rated 5 out of 5 by from Beautiful picture and energy efficient! I purchased this as a second tv for my home. I already have a LG Plasma 50" that is to die for and was surprised by the quality of picture this TV has! Just a stunning picture after I calibrated everything. And also, the tuner that brings in the channels is very effective and brings in programming without the use of an antenna amplifier so I can tell its quality through and through. After the TV goes through its warmup and break in period, you just cant ask for better. In all, its energy efficient, beautiful big picture which is 1080 resolution which means less strain on your eyes and the channel tuner holds on to the channel. I cant ask for anything more!

Rated 5 out of 5 by from Perfect I bought this as a Christmas gift for my boyfriend as our main TV. It was a great Black Friday buy, and has worked perfectly thus far. We do have a computer and sound system hooked up to it, and are very happy with it.

Rated 4 out of 5 by from Great Product For A Great Price We absolutely love the TV. The picture is great and it looks sharp and modern. Additional speakers are necessary, however, as the sound is very weak. Great buy!

Rated 5 out of 5 by from Really great I got it and really love. The quality is really good. The price is better for my budget.

Rated 5 out of 5 by from Great picture This is a great TV for the price. You don't need any other fancy unit to do what this one can. The audio is the only drawback. Picture is awesome, and the broadcast in 1080i is fantastic.

Im trying to connect a wireless audio transmitter, however I'm lacking the 3.5mm input for my audio. Any ideas of what I can use other than the RCA inputs, b/c they do not work, neither does RS232 mini jack. Maybe a 3.5mm to optical or hdmi? Want BT!

Asked by: Colita
Optical to 3.5 mm jack would be the best option. However, we would not be able to guarantee compatibility or functionality of the adapter with the TV. Nor do we have a recommended brand to use. ^AC
