I purchased a Hisense Roku TV through Walmart that had a one year warranty. This warranty is not worth the paper it is printed on. In less than one year the tube started going bad and is getting progressively worse. Hisense indicated that "we have come to the conclusion that your unit has physical damage". When asked to provide a reason for their conclusion they state: "we are unable to state what kind of physical damage as we did not see what took place". The TV is on top of a bedroom chest of drawers and has not been moved since day one. It has never been dropped or damaged in any way. I would never buy any Hisense electronic item again. I should know better since Walmart only sells cheap crap.
