I recently purchased a Vizio 50 inch TV and I can't seem to get it connected to my wifi. It connects with 4G but not wifi and when I go into the settings for the internet connection, it says that there are no networks detected. I don't know what to do or how to fix this. I read on a forum that in some cases, you have to go into the settings and turn off the wifi. This is where I am stuck. I don't have any other suggestions. Do you guys have any suggestions on how to fix this? ------------------ I could use some help and suggestions, cause the picture on my Vizio 50 tv sucks when it comes to the sound. You can hear it, but the volume isn't loud enough. Thanks I need help when I am watching my tv and I want to watch something on netflix or vudu the picture will all of a sudden just go black and says no signal, then after about a min will come back and say wait for playback error. What should I do? The Vizio 50 LED TV is excellent, but it has some problems in connecting to the internet. I have 5 other Vizio TV's and they all connect to the internet well. It may be a setting on my Vizio 50. I'm having issues with my vizio tv. Whenever I go on line, it takes forever for any page to load, the screen goes black and the search bar comes up. The question is how do I fix this problem? Hi all! I recently purchased a Sharp 50in LED 3D LED LCD HDTV.
