I had the same problem with my 37L and 42L Vizio TVs but my 26w vizio TV guide works perfectly. on 12/28/2009 I called vizio about the problem and they said that Vizio lost a law suit with a company (tech didn't tell me the company name) that said that Vizio did not own the "TVGUIDE" technology b/c the other company invented it first. So, Vizio was forced to turn this feature off in their new TV's so that's why my guide button with older Vizio 26" TV (bought in 2007) works and my newer 37" and 42" Vizio TV's (Bought in 2008) do not even though the instructions are still in their user manuals which the tech said will be removed in future user manuals. BTW I got the same result with comcast basic cable service and over the air roof top antenna.
I have a Vizio M470SL used the code for the LG (0178)..worked !
To program a Comcast remote to a Vizio TV, first, turn on the TV. Then, press and hold the "TV" button on the remote until the LED light changes from red to green, then release the button. Next, press and hold the "Setup" button until the LED turns green again, then release it. Finally, enter the code for Vizio TVs, which can typically be found in the remote's user manual or online; if entered correctly, the LED will turn off. Test the remote by trying to control the TV volume or power.
I have a cosmotech tv and it uses the same remote codes as a VIZIO tv. I recently got a Vizio blu-ray player as well and the remote said that it will work with a VIZIO tv only, and it worked with my cosmotech TV.
0178 this did not work for me. 0134 LG code worked for me.
