Att uverse code vizio tv E470-A0 - Zenith ZEN700 Remote Control

Sorry we have no way to look that up at this website.

T con board affects picture only. since you are having issues with both the picture and audio I would suspect the main board which deals with both.

The front LED light that shows whether the TV is on or off will flash so many ... press and hold the power button for 5 seconds upon plugging the TV in. ... The flashing code I got meant the power supply was bad.

It is in here

Hi,
Maybe too late for you but ATT just gave me a code that works with my Vizio plasma. Code is 1343. Even the mute works correctly. They gave me some others to try but I didn't need them. Other codes were 1018, 0030 and 0056.

The documentation that came with my U-Verse equipment doesn't list Vizio products, but I have been using 1343 which I saw suggested on another website. AT&T's support site has a new code list (http://www.att.com/support_media/images/pdf/uverse/set-up-code-list.pdf) showing Vizio under the TV section as 1489 and in the HDTV section as 1429, 1433, or 1439.

None of the codes listed for Vizio work with my Vizio LCD(model VO370M), but the 1343 code I've been using successfully is listed in the new list as an LG HDTV code.
