this be a complaint about the Panasonic sc-ht733 home theater system . this system repeatedly shut itself off for no apparent reason . Panasonic have I take it twice to a local electronic store under warranty but they be unable to fix it . I ultimately return it through the merchant and buy another brand . I will never buy any Panasonic product again , not because it be defective , but because of the way Panasonic address the problem . it be a big problem to disconnect everything and take it in while they perform trial and error . Panasonic should have just replace it . I do not like the attitude of anyone I speak with there . I also be not even able to complain directly to the company . on the phone they give I a case number and never follow up . a online feedback form do not work . I be through with this company .
