LG has initiated a voluntary recall program in South Korea to offer free repair of some OLED TVs from 2016 to 2019, according to Yonhap. It is investigating TVs sold in other markets too.
Overheating OLED TVs
LG believes that approximately 60000 OLED TVs sold have a bad component that could under some circumstances lead to issues, of which 22000 have been fixed already. It impacts 65 and 77-inch models – but apparently not 55-inch models – from the 2016, 2017, 2018, and 2019 generations (full list below).
It is not the actual OLED panel that is overheating but rather a power board component, according to LG. The report from South Korea's Yonhap news agency noted that the "power boards carry the risk of current overflow after performance degradation of a current-controlling component".
The company said that OLED TVs sold outside of South Korea are not subject to the repairs at this time. However, in a statement to The Verge the company noted that it is "investigating other markets" for potential issues.
It is not clear why it would affect only TVs sold in South Korea and it remains to be seen if LG identifies any issues in TVs sold in international markets. Update: In a statement to Flatpanels the company said that it is "basically a component meant to reduce electric current noise that was analysed and discovered could raise temperatures on the PCB".
It is a voluntary recall from LG as it has not been mandated by any authorities. Repairs are offered free of charge in South Korea.
