we have this system for 5 year with not a lot of usage on it and it finally break . the interface between the remote control and the main unit stop work . I have try new battery and none of the function on the remote work . out of all the japanese brand electronics I own at home , Panasonic have the least reliability and quality . I have never have any problem with my Sony , Toshiba , Sharp and Sanyo electronics . in the last 8 year , my Panasonic VCR break , the DVD\/VCR Home Theater break , and my 50 disc Stereo Changer break . all of the other japanese Electronics in the household be still functional . my last Panasonic finally break and I will no longer purchase another Panasonic ever again .
