LG is probing an allegation that some of its smart TVs sent details of viewing behaviour back to the electronics firm without user consent even after activation of a privacy setting.
The probe was sparked after reports from UK-based IT consultant who specified about how his Smart TV was transmitting data about the channels being viewed.
LG spokesman told BBC that the company was looking into the complaint.
"Customer privacy is a top priority at LG Electronics and as such, we take this issue very seriously," he said.
"We are looking into reports that certain viewing information on LG Smart TVs was shared without consent.
"LG offers many unique Smart TV models which differ in features and functions from one market to another, so we ask for your patience and understanding as we look into this matter."
Reports also indicated that the TVs even uploaded data about the contents of devices connected to the TV, including files saved in USB hard drive as well as the TV’s unique identification information.
The UK Information Commissioner Office spokesman said that the agency was looking into the issue.
"We have recently been made aware of a possible data breach which may involve LG Smart TVs,"he said.
"We will be making enquiries into the circumstances of the alleged breach of the Data Protection Act before deciding what action, if any, needs to be taken."
