I have a 2 1/2 year old 42" LCD Vizio SV421XVT. A week ago the speakers could not be turned off with the menu. I was able to toggle the off but sound still came out. I was trying to use my home theatre so I turned the sound down completely on the tv. Then a couple of days later the remote stopped working and so did the cable universal remote. I talked with Vizio and they suggested removing the batteries etc but nothing worked. One tech suggested replacing the IR sensor. So I ordered and installed the new IR sensor and still nothing. Also, before the new IR sensor sometimes I was unable to turn off the tv with the on/off switch on the set so I had to unplug it. The tv works and has a great picture but this remote thing is inconvenient...any suggestions?
