Question about Vizio L37 Television
I have a new VO37LF Vizio. I was on the phone with Vizio tech support today trying to get PIP to work. I got that to work.HOWEVER, now when I go to channel 43-1 over my antenna, it shuts off the TV. This happens with no other channel and it did not happen before. I have done all the "resets" and I have unplugged the unit and held in the power button on the TV (supposedly that does a capacitor clear. I still have the problem. Spent 45 minutes oon the phone with the tech and he has no idea.

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.

I had a similar 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. I didnt hear an arcing sound though.
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. I would check the ceramic fuse first on the board that gets power from the plug.
HOW I FIXED MINE: 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.

LCD's use a colorful crystal see through display which only visible when light is shining through it. if you have sound and no picture it's always a faulty PSU. Very easy to change out actually.
