Question about Vizio VO47L 47 in. LCD TV

2 Answers

We have a Vizio model # GV47LFHDTV10A. When we went to bed last night the tv was working fine. We 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. Not a blue screen like when you didn't turn on the satellite. Also, you 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.

For the cheap guy like me who will probably do more harm than good:
Also check for the F3 Fuse on that same main input board. It is located in the upper right corner. Hard wired fuses; very small. You will see F1-F4 (F4 is empty). You can solder a replacement fuse right over it. I would recommend piggybacking the fuse with a fuse you can replace. Will need the holder and a new fuse. 6 bucks.
Doesn't solve problem, but I can go another 2 1/2 years and the wife won't blame me for screwing up the TV in the first place.

    Fixed my 47" GV47L for $7.18... Did the F3 Fuse bypass solution, and it worked like a champ!!! No problems since! The part that took the longest was the drive to Radio Shack!!!

    I have the same problem. You can get the part at mouser electronics online. The F3 fuse looks to be a littelfuse manufacturing number: 045101.5MRL. For those looking to repair themselves.

I had the same problem after having a Vizio for 2 and a half years. I left the room for a minute, i came back and the screen went black. There was still power to the unit and you could see that the back light was working, just no picture, no sound, and you couldn't use any of the buttons. The only way to turn it off was to unplug it. It would then start up, with the Vizio logo going from orange to white, and then do the same thing all over, no pic or sound.

HOW I FIXED MINE:Look through the back vents for a white light to make sure the backlight still works. I ordered a new "main PCB" from tigerdirectparts.com (you can also use searspartsdirect.com). This is the circuit board with all of the inputs on it (hdmi, cable, etc.) I opened it up, disconnected the old one, put in a new one and now it works fine. I used both serial numbers on the board to search for it online. It cost me $144 to do it, but that's better than $450 for a new TV. My tv is the vx32l hdtv10a. I hope that helps.

    I have the same condition. What parts did you get at Radio Shack to fix it? Thanks. jg

  • nevinl Dec 31, 2010

    I Fixed my 47" GV47L for under $12... By passed the F3 Fuse, and it worked like a champ!!! No problems since!
    Hardest part for me was the soldering since I have jittery hands and not much soldering experience.
    Need a 15 amp fuse and fuse holder. I got mine at radio shack and used an auto inline fuse holder (see picture) others online gave me this info and I followed their directions to success!
