Vizio xvt3d554sv Used menu button to set up remote for cable box presses power button when I turned the tv back on menu function didn't respond.. I've taken out the remote batteries and have turned tv off and unplugged it plugged back in and menu function still dosent work
If only one button does not work at all or all do not work the unit may have a lock out feature that would be explained in the owners manual.
I wasn't locked out, after an hr off messin around I figured it out.. As I was trying to set up my tv to my cable box, I unintentionally made my tv think it had produced the right code for the cable box and was set up.. Now that had happened the menu button was set to work with the cable box and not my tv. I went to another input and the menu button would respond hence not being used with cable box since different input being used. I was then able to switch back to the input being used with the cable box and enter the appropriate code.. And the tv works just fine, but doing this you can't use the tv menu button you'll be using the cable box menu.. Hope this helps anyone who may have the same problem..

I had the same 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. 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.
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.

I EMAILED VIZIO ABOUT MY PROBLEM. THEY RESPONDED IN 3 DAYS. THE TECH AND I THEN TRADED A COUPLE OF EMAILS. HE CONFIRMED THE INFO ABOUT THE TV WITH ME. HE EMAILED ME THE SOLUTION TO THE PROBLEM AND PART NUMBER. IT WAS THE MAIN BOARD. I ORDERED THE PART AT VIZPARTS.COM FOR ABOUT 180.00. INSTALLED IT MYSELF AND THE TV WORKS FINE. I WISH IT HAD BEEN UNDER WARRANTY BUT IT WAS 18 MONTHS OLD AND THE WARRANTY WAS FOR 12 MONTHS.
