South Korea's LG Electronics says it will correct a "bug" on some of its smart TVs after admitting they send information about viewers back to the company without their permission.
The world's second-largest TV maker launched an investigation after UK-based IT consultant Jason Huntley raised the issue in a blog.
Huntley said LG continued to collect information on which channel he was watching even after he turned off the data collection feature.
"We have found some of our smart TVs continue to transmit viewing information even when the function is turned off by the viewer," a spokesman said on Friday.
"We are preparing a firmware update to roll out soon that will correct this bug."

Huntley welcomed the move.
LG's rival Samsung Electronics, the world's largest TV maker, said its products had not experienced such a problem.
