Hello, I purchased an LG Oled B6 TV from Best Buy in June of 2016. Shortly thereafter, I purchased insurance for this TV from a company called Square Trade through Costco. The TV performed beautifully until early in 2018 when a vertical line would appear on the left side of the screen. I called Square Trade and they verified that there was a hardware problem and sent me a brand new Oled B7 in March 2018. The manufacture date of this TV was also March 2018, so I know it was brand new. This B7 worked great until about a month ago, I noticed image retention, or "burn-in". I tried refreshing the pixels several times, but it did not fix the problem. I called LG Customer Service on May 15, 2021 to see if there was a known issue with this TV and they opened a case, #CNN210515648482. I received a call from Customer Service asking for the receipt for the TV. I explained that this was a replacement for a defective TV, so there was only the receipt for the original B6 TV. I was informed that if I didn't have a receipt for the damaged B7 TV, they couldn't help me. Since it was an insurance replacement, there is no receipt. I write this to say that I love the picture quality of the LG Oled TV's but their reliability is very poor. I've had 2 Oled TV's that have gone bad in a 5 year period. Now I'm stuck with annoying burn-in. That's all I wanted to say. Thanks for listening. Stan Smith [protected]
