I have a Vizio model # GV47LFHDTV10A. Tried to turn it on this morning and nothing. There is some power. The Vizio logo lights up and so does the control strip on the front of the unit lights up as well. But there is no picture or sound. There is just a black screen. Also, have to unplug the tv to turn it off. It will not turn off by touching the power on the unit or with the remote control. I checked the F3 fuse with a multimeter and it is fine. Any other ideas?

You guys ROCK, had the same problem TV was fine last night but would not turn on the next morning, used the F3 fuse by pass fix, and worked like a charm. Most time consuming effort was taking all the screws out to remove the back, and the trip to Radio Shack!! Please note however the fuse should be 1.5 amps not 15. The folks at Radio Shack were experts and knew exactly what parts were required. Thanks again for the help!!
