Black screen on tv. I was watching the tv, heard a loud "pop" and the screen went black

Question

I was watching the tv, heard a loud "pop" and the screen went black with no sound. Could it be a bad module ?there was a humming sound for the longest time, not sure if this was a sign? the screen went black just after a load pop. TV was purchased less than a year and a half ago. does any one know of a recall? seem that this is a major problem for allot of Vizio owners. i have the 47 inch lcd. not sure if the model number below is correct.
