What people are saying

Rated 1 out of 5 by from Short Warranty, Unhelpful Support, Hardware Defect Panel started flickering exactly two weeks after the extremely ungenerous 1 year warranty expired and they have given me the rudest, most blatent and purposefully unhelpful support I've ever received from a company. Said they would open a case to review and never did, even after reaching out two more times asking. This was my third LG OLED added to my house since 2017, and I've never had any issues until the 2024 model. Extremely disappointed in their product lifespan and support these days. Guess it was the last one I'm buying from them.

Rated 1 out of 5 by from Beware LG TVs I bought the C3 6 months ago after owning the CX for 4 years. A few days ago my CX failed after only light to moderate use since I bought it. Sometimes I wouldn’t use it for weeks. I was extremely careful to avoid any burn in and ironically the panel is in perfect condition, but it’s the internal components you need to be worried about. The power supply board or possibly the main board failed after having the CX on for a few hours the other night. After doing some research, I’ve noticed many other complaints about faulty power supplies starting about a year ago. The customer response team has been entirely inadequate. Apparently the CX only had a 2 year warranty and they only direct me to their OOW repair team where I’d need to spend over $500 to fix a $1500 TV. Now I’m worried the $2500 C3 I purchased will fail in the same way and obviously I wouldn’t have purchased it if I knew this was the way they treat loyal customers. The C3 provides a great picture and I only hope the internal components don’t end up being the same shoddy quality as the CX.
