If the main fuse was blown you would not hear any sounds when you plug
it in. There are lots of other components that, if faulty, could
cause the TV to not come on. The only way to know is to have a tech
open up the back and perform some basic troubleshooting. TAKE your
television to a service shop for, at the very least, a repair cost
estimate so you can make an intelligent repair decision with facts
instead of guesses.
