Not just tv's.. anything electronic now it seems!
My parents have gone through 2 if not 3 microwave ovens in the past decade, and of each of them had them repaired at least once for the magnetron and circuit boards.. All were Panasonic "inverter technology" as well... Meanwhile the old microwave they bought in 1985, a "Quazar" still happily buzzes away in my kitchen and has never been opened up for servicing!
