Known issues and safety

Recall check: we searched GOV.UK product safety alerts, reports and recalls (Office for Product Safety and Standards) for “LG OLED television” and “LG Electronics” on 18 October 2026. No notice for an LG television was found [2]. An LG notice for ESS home batteries (2022) is for a different product.

We did not open LG’s manual, so we cannot summarise installation or safety instructions. LG’s page links a product information sheet and energy labels [1].
