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.

I just called Vizio and they said to unplug the TV, then physically hold in the power button on the TV for 2 minutes.

SOURCE: tv screen went blank

sound like the inverter circuit board problem. check & replace back same part# inverter circuit board. hopefully could help!!

If screen is gray glowing, the T-CON is bad or it is not getting the 12vdc from the logic board. You may have problem with logic board but do some voltage checking first.
If you are going to DIY and have proper tools and know safety precaution then please read on:

Testimonial: "I am not much of a do it yourself guy when it comes to electronics but I think I might give this a try--this gives me a good place to start--I'll check your trouble shooting guide and then the voltages and see if I can fix this--I have already replaced the TV but if I can get it going I'll have one for the spare bedroom---thanks for your advice.
