Same

Our Vizio GV47L would not power up (the "Vizio" emblem on the front of the set was black also). I got scared reading the one solution here which talked about a soldered fuse, so I called in the repair folks (they offered a free estimate on site). Initially, the repairman said he would have to take the set off-site, and we were looking at hundreds of dollars for the estimate and resolution. I pushed the fuse issue. He agreed to open the set for free, but if it was a fuse the charge would be $75. I agreed. He layed the set screen down on a padded table (you will need to do this to unscrew the speakers). There are lots of screws, and typically the ones in the middle of a line of screws are different sizes. Sure enough, when he opened the panel I could see that there was only one regular fuse on the whole tv. It is on the Power Board circuit panel. If you are looking forward from the back of the unit it is near the top left position. The fuse is not soldered. He popped it out and sure enough it was blown. He installed a new fuse and the tv works just fine again. It was a cheap fix at $75, but I'm reasonably handy and could have repaced the fuse myself for a couple of bucks. Oh well, live and learn. I hope this helps somebody!
