Question about Vizio P4221 Television
It takes a fair amount of power to make an audible noise like
this. Only the power supplies are suspect. Either the low
voltage supply that runs the TV's "smarts" or the high-voltage
supply that powers the screen. Either way, it is bad news - You
do have this under warranty don't you?
I don't care which of the new TV technologies you buy, they are all doomed to expensive repairs. Always keep them under warranty.
