Question about Vizio E3D470VX 47 in. 3D LCD HDTV
TV turns off when I plug in anything on the A/V card. HDMI, RCA, coax cable from a Cable box or DVD. Stays on if nothing is plugged in. What is the issue? A/V main board or power board?

Well, your TV is still under warranty. That's the good part.
The only thing I can recommend without voiding the warranty is leaving the TV unplugged for 30min. That way, the TV can reset itself and hopefully correct the problem.
If that doesn't solve the problem, it's time to use the VIZIO warranty.
Here's contact info if you need it.

My 37 inch vizio did the same thing. go to your menu screen on the tv and go sound. My tv has an option to turn speakers on/off. Once I turned my speakers off and the back on again everything worked great. hope I helped! if I did please let me know! youtube.com/xniax1

I recently had the same problem with my vizeo hdmi port # 1 going bad. Tried everything to fix and called vizeo. There solution for a master reset was turn off tv and unplug from the wall. then hold down the power button for 30 secs and let go. plug the tv back in and hold down the volume down and input select buttons down on side of the tv for 15 secs. release the buttons and turn the tv on after powering down all the components connectd to the tv. If this does not work they told me you need to have it sericed for a bad hdmi input. Hope this info helps anyone out there. It didn't work for me. Its a bummer cause the tv is well taken care of and only 18 months old. Best of luck to all others.
