But the overseas equipment manufacturer claims there weren't any defects in the equipment, which shows different opinions about who is to blame.
Samsung Electronics is said to consider taking legal action if it fails to reach an agreement with the manufacturer.
"We conducted the investigation by ourselves to find out the cause. The power failure was not because of Korea Electronic Power Corporation, not because of systemic error, management error and outdated facilities and not caused by employees. We tentatively concluded that problems in the power distribution facilities initiated the power failures," said Yoon Jong-yong, CEO of Samsung Electronics.
Samsung thinks that humans are not the cause of the problem. Therefore, it has no plans to change personnel as a punishment.
"Samsung Electronics claims compensation for the power failure from the manufacturer in an indirect way and Samsung will resort to legal action if they can't reach an agreement smoothly," said a source who knows Samsung well.
"We are not able to announce our position in this issue. If we make the final decision, we will take action accordingly," a Samsung official said. His remark indicates that the company could go to court.
Contrary to the previous report, Samsung Electronics will claim insurance money from Samsung Fire and Marine Insurance when the damage becomes clear.
