My Panasonic bit the dust after about five years of use with a light show. I believe the magnetron shorted and burnt out the power supply. As I was microwaving water for tea, there was a bright white light on the inside of the microwave. Family also described a similar failure around the same time frame of ownership. I enjoyed that microwave before that happened and was thoroughly impressed with the ice cream soften setting.
