Query: Poor customer service

Stay away from any products from Hitachi. I bought the TV 30 days ago. The shipping and delivery was quick and great. But after 2 days the TV broke. Now 30 days later it still has not been repaired. The service centers provided by Hitachi are incompetent and they receive no tech support from Hitachi. Also do not buy TVs this size on the internet. Amazon and it affiliate retailers will not accept returns for defective TVs if more than 37" in size. You are at the mercy of the manufacturer and in this case Hitachi has provided no service. Stay away from Hitachi.
