The firm is offering to replace the power boards on the screens, with 18 models from 2016 to 2019 affected.
So far LG has already swapped the component on 22,000 out of the 60,000 TVs with the glitch.
In a statement, they said: "The overheating issue occurred only in very few models out of the total that used the component, but we will provide free component swaps for all of them for customer safety," LG said, apologising to customers for the inconvenience.
The affected models are as follows: The 2016 models of OLED65E6, OLED65G6, and OLED77G6; the 2017 models of OLED65B7, OLED65C7, OLED65E7, OLED65G7, OLED65W7, OLED77G7, and OLED77W7; for 2018 models, they are OLED65G8, OLED65W8, OLED77C8, and OLED77W8; and the affected 2019 models are OLED65W9, OLED77B9, OLED77C9, and OLED77W9.
Meanwhile, it was recently reported that LG's plans to start mass producing OLED TV panels in Paju, South Korea, have been stalled once again.
The blow comes amid the coronavirus pandemic.
They had aimed to start production between 2021 and 2022, but that was pushed back to 2023, and now it reportedly won't begin until 2025 to 2026.
