I had the same problem with my tv.No sound! I finally figured it out. It was the speaker wires! Once I changed them to a slightly stronger speaker wire, it worked great! I have sound to my tv and I haven't had any problems since then.

Same problem with my set. The volume was either fully up, or fully down (usually down), and other controls didn't work- like I couldn't access the menus and could not adjust the width of the screen/aspect ratio.
I lived with it for about six weeks, then took the back off the TV. Just now it seems to be fixed, but I don't know if it will last.
I disconnected the wire leading to the channel up/down, volume up/down and source board, turned on the tv, turned it back off, reconnected the cable, and everything seems fine now.

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.

The fault may be on the control board. Sometimes the button switches can be stuck, or there may be something causing some conduction on the control circuit board. It is also possible to have a component failure that is causing a continuous command to keep the volume to the high position.
Something that causes failures of controls in TV sets is when people clean the screen, they spray liquid cleaner on the screen. Some of it drips down in to the controls and on to the circuit board. This will usually cause damage, and thus the set will require shop service.
