wow. have you tried a power line conditioner such as a Monster power or even a BIG surge protector? just to see if there is a line fault anywhere? also, can you take a picture of wht the TV looks like with the sub on and then off? to show us the difference? where is the sub located? i have never heard of this type of problem before, however, if the subs are dying, they there is obviously a problem with THEM and not your tv. what has Axiom said about all this??? i have had numerous subs, from many different manufacturers...and i have never had a problem like that. we'll help if we can, and of COURSE you want a sub...it's what makes the HT experience worth while. we'll figure it out i'm sure.
