I've been told that my main power supple board has failed in my less then a year old magnavox plasma 42" tv.My question is would a cooling fan help prevent this?
baja, probably not my friend. When the engineers design these monsters, they go and use only the best parts to use in thier designs. Then comes the quaility assurance peeps. They say" Oh you don't need that, and this will help cut the cost of the design. It''s the cheap skates at the design plant that makes these sets breakdown the way they do by the simple use of under rated parts. I don't know of one engineer who would design a device or an electronic engineer who would use a sub-standard part as part of thier own design. Cooling fans were used in earlyer solid state elctronics, but as the power consumtion became less, the engineers stopped using them and simply started using larger heat sinks to absorb the heat in a TV set. I would say, no in your case and is simply a breakdown caused from a power surge or simply a componet failure, as the parts do not last forever.
