Expensive TV that wont pair a set of headphones.

Submitted by Vjohn - 11/26/2017

I cannot believe I spent this much money and the LG TV will not pair to a new bluetooth headphone set. I called support and they said it may or may not. Well it did not pair. Unbelievable. I will not recommend nor buy another LG TV.

2 Year Lifespan

Submitted by TVSadness - 11/9/2017

I purchased the LG 55EC9300 OLED in October 2015. In the beginning of October 2017 it began displaying wide vertical band and partial screen freezing. A week later it powered itself off during operation and never came on again. Research into this problem revealed it to be a fairly common one. A television at this tier should last longer than 2 years. I am extremely disappointed in this product and regret my purchase.

OLED can suffer from burn-in screen damage

Submitted by NeverCNN - 10/17/2017

During the period of the last Presidential Election season I had my set tuned into CNN for long hours each day. Due to CNNs practice of constantly except during commercials displaying their large CNN banner across the bottom of the screen I discovered that now many many months later I still have that banner burned into my screen. There is no cure for this damage. I was aware of this problem with CRT monitors and TVs but I failed to notice the cautionary mention of this issue in the Manual provided with my set. I ca see why gamers would be well advised to steer clear of this tech if they plan on using it to play hours of video games in lengthy sessions. I failed to realize until it was too late that any programing practices like those of CNN could cause irreparable harm to my investment. As a result this set is no longer EVER tuned into any live or used to play any DVR programming from CNN. I will forever have a pale yellow ghost of that image with all my viewing.

Life is really good with LG

Submitted by Sathiesh stanley - 9/22/2017

I got this oled tv a year ago. Within 2 months the tv stopped working and i was disappointed and had a thought if i made a wrong decision. Thats when LG service came and ensured that everything was taken care.They changed the oled panel and fixed the issue. From then on i always felt with LG i m in safe hands. Now about the tv. DesignAmazing picture quality easy connectivity. Now the cons of the product sound quality is not good with internal speakers webos interface is slow power button could have been made simple rather than having a joystick kinda module. Store executives and installation people need to know that 3d works with glasses post removing the plastics from the screen when its new. This is just a feedback bcos i was told that 3d is not supported and that some module is faulty later a senior lg tech removed the plastics and got it working. Overall lg is awesome and i feel happy and proud to be its family member. Thank you Sathiesh stanley

Stopped working

Submitted by JUNK OLED - 8/27/2017

I gave one star because zero wasnt an option. The picture is amazing until the unit stops working so be sure to get the extended warranty. My set lasted a year and nine months now Im watching on a ten year old Panasonic that has never given me problems and was a third the cost. Still trying to get customer service to cover repair.

Dead at 14 months

Submitted by A Toledo - 1/23/2017

I did enjoy the the OLED picture quality but just after 14 months of service - the unit is dead. It displayed black areas on the display for a few seconds and the unit powered off and would not turn back on again. I have it connected to a surge protector/line conditioner Panamax so I would not suspect a power issue caused it. With the units cost and useful service life this was a bad purchase.

Great image quality but... TV prone to defects

Submitted by alexv - 11/13/2016

Image quality is amazing. But after one year of very good experience the TV stopped turning on for no reason. Ive searched the internet that other people had similar issues. So I wouldnt recommend the product. Its too expensive to last only 1 year.

Great Blacks Share picture

Submitted by Grrr1lla - 4/8/2016

I purchased this tv about a month ago. It has a yellow zone in the middle of the curve on white screens. I love hockey but the yellow zone is very distracting. Very sad. The 6 year old Panasonic plasma it replaced didnt hold a candle to this as far as blacks and sharpness but there werent no pixel/picture issues. I read the newer ones were a little better with this issue.
