Vizio e420vse It has worked fine for just short of a month with great picture and sound. Now I moved back to school, plugged it in, and it has worked well for almost a week. This morning when I powered on my tv I received audio but no video picture. Powered on and off multiple times, same thing. Now I just have a short blink of the white indicator light, no display, no sound. It appears to not power on at all. Any advice?

SOURCE: no sound and no picture

It may well be the power supply. Filter capacitors have a nasty tendency of blowing, as well as voltage control ICs. If the filter blows, you end up with a shaky DC signal that can't be effectively used by digital components (which make up about 80% of modern TV circuits). If you're within warranty/exchange then go for the manufacturer. If not, and you're comfortable with opening these things, then you can carefully (after unplugging and allowing it to discharge) take a glance inside. If any capacitor(s) are visibly blown out, then there's your problem.

If you are using a set top box this might be caused by turnig the box on at the same tie as you turn the tv on or slightly after you turn the tv on.  If you are using compnent or HDMI inputs the set needs to see the signal as it is turned on to know what formt the signal is in.

SOURCE: vizio 47" lcd no picture no sound has power

this could be one of two problem. first, check if you have back light. If you do then the problem is with the M/B. Second, if you don't have back light then the inverter is bad and needs to be replace.

SOURCE: no picture or sound, light comes on in the front and have to unplug tv to turn it off.

I had this exact problem on my Vizio 47" HDTV. I removed the speakers and all the screws on the back cover. Took the cover off and located the fuses on the largest circuit board. The are in the upper right hand corner of the board. There are 3 of them in a row labeled LF 1.5, LF 3.0 and LF 3.0. The are white in color with copper ends. I took a volt meter and measured continuity across all fuses individually and found the LF 1.5 to be blown. The guy at the electronics store sold me a barrel 1.5A fuse and told me to soldier it across the top of the blown fuse. It took an extra set of hands but the TV works perfectly.
