My Vizio TV was set to HDMI and connected to my computer to watch movies. A thunderstorm fried my PC and I can't reset the TV input from HDMI to TV. The Vizio will Not even turn on unless connected to the HDMI port on my computer. How can I reset the input to TV if the TV will not even turn on without being connected to the computer? Please help. Thanks
I am also having the same symptoms for my SV421XVT. TV works great except all HDMI ports are not receiving signal. Devices work through the AV Ports, and TV reception is fine. New Roku box is also not working through HDMI but works with AV. Wish I had a solution to this.
On a another forum for another TV it was suggested that boards need to be replaced. I hope I can get these boards for a reasonable cost.

Im no expert on the subject, but I use my L37 for a monitor, and use just the vga adapter. It works good as a monitor, and both dvds and my hdtv wonder tuner card look great through the vga connection. They do make adapters for dvi to hdmi. Although, hdmi also carries sound, but you wont get that out of your dvi output from your card. So you might not have sound when using that connection, as your tv may not look to the headphone type jack used for sound imput from your computer when you select the hdmi source on it. If you have speakers already connected to your computer you may not care. Also if you have a 720 p Vizio, 1366x768 is the highest resolution you are going to get out of it anyway, if I'm not mistaken. I'm Not sure why you would need 2 connectios to the same monitor either. I posted 1 link below because they had several dvi to hdmi adapters. Hope that helps.

Our Vizio started doing the same thing after only three weeks, except it was also showing green pixel when we watched DVDs. After checking this site and others and trying all the "tweaking" advised, I finally called Vizio's customer support. They were extremely polite and tried to help over the phone, but had to send someone to the house to make the repair (anything 40 inches or larger earns a house call). The tech arrived on time and was extremely professional and pleasant -- he had to replace the daughter board and LVDS cables. So far, so good.

When you say it does not turn on, do you mean that the LED at the front indicates its on but there is no picture or sound or is it stuck in standby mode? Please provide this info so that I can tell you what the problem is and how to fix it.
