Question about Vizio GV47LF Television
Picture lost sound lost as if tv was shut off but power light stayed on. cannot shut off tv without unplugging at power source. vizio 47" lcd I have a Vizio 47" HDTV model number GV47L FHDTV10A. I have no picture or sound, but i do have power, the vizio light comes on with i turn the tv on, but i can only shut it off if i unplug it.
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.

This is an outstanding repair suggestion. I had the same symptoms and just completed soldering in a fuse as suggested (actually I attached hookup wires to the blown fuse on the board and connected in a fuse holder so that if it blows again the replacement will be simpler). 1.5 hrs labor and a few spare parts around the house and my TV works like new. Thanks for posting.

I see a couple sizes for the fuses. Did you use the 5x20mm or the 3.6x10mm fuses? the 5x20 have fuse holders which would be easier to solder on.

Your main board is bad. Call company if under warranty.

If you are familiar with the old glass car fuses that is what they look like but are white( I believe ceramic) with silver caps on each end and soldered/hard wired directly to the board. You cannot remove them without patience and a soldering iron. You can, with an ohm meter go across (touch leads of ohmmeter) to each end of the fuse to see if you see a short. Depending on how accurate your meter is, it should read 0 ohms or show some type of continuity/connection between the two leads of your meter. Hope this helps?
