new digital TV
has a switching power supply, the MSW inverter will be just fine
i ran MSW for many years , with NO problems
the TWO items most reported as having problems with MSW are microwave ovens
and electric blankets/heating pads with digital controllers
the third item is the charging brick power supplies of some electronics like laptops
the newer smaller laptop power bricks, seem to run "hotter" with MSW than the older heavier ones ... could be the lack of a transformer and total dependence on chopping up the wave form for the correct voltage
