Believe it or not this has resolved my issue, and all has been well for about a week now. So I was wondering if anyone else has had this problem with this tv, and if I can expect this issue to resurface requiring this fix to be done every so often?
I'm tempted to return for a dumb TV, and go the Roku route. Thoughts? Thanks for any help.
I called Vizio and all they have me do is reset all wireless settings in the TV which is more trouble than its worth, because then I get to log back into everything with the stupid non-keyboard having remote.
I have a feeling it has to do with the wireless hardware in the TV not being all that capable.
My advice is to get a diff brand TV if you're going to stick with one of the "smart" variety.
I was having a similar problem. I could turn the set on and within 15 seconds I would loose function control (volume, mute, channel, menu, etc) on both the remote and side panel buttons. After a call to VIZIO tech support, and trying numerous troubleshooting steps, VIZIO indicated that a technician visit was called for. He arrived yesterday to replace the main board. After initial installation the problem appeared to be solved.
When you do a replacement of the main board you have to go through the setup routine again. To save time, while the tech was there, I did not initially do the internet connection. As he was doing his completion paperwork, I went back into the system setup and proceeded to do my wireless connection setup. As soon as I did I lost function capability again.
The Service Tech in the house contacted his tech support at HD Repair in Florida (VIZIO"S repair support folks). HD repair stated that there appeared to be a conflict with my Linksys E4200 router and that I should look for a router software update or try another router. There was nothing else they could do.
Today I called the VIZIO tech support number again. I explained the situation to the young lady and was told that this was a known problem and appeared to be a problem associated with file sharing. According to her the VIZIO TV does not permit file sharing and will lock up when queried by the router. Normally file sharing, on a PC for instance, is controlled on the individual device. Since there is no place on the TV to turn off a file sharing function, and I cannot find anyplace in the E4200 to do this I am at a loss. She did not have an adequate answer. . I don't understand how this can be true or you would never be able to use the "Smart TV" functions.
Bottom line is that I can use my TV as long as I don't connect to the internet via my router. I cannot find anything in the E4200 setup that would allow me to control file sharing for a specific device.
It is also interesting that there appears to no way, in the TV setup, to "Disconnect" a wireless connection once it is setup, short of doing a "Factory Reset" to clear memory. I also tried doing a hard wire connection with the same results, at least this made trouble shooting easier since I regained function control as soon as the Ethernet cable was disconnected.
After another call to VIZIO and some additional troubleshooting I have found that File Sharing is indeed the problem. If I turn off file sharing, on the two computers I have connected on my home network,then I regain controls on the TV. I have not found a way in my E4200 to turn off File Sharing for just the TV and doing this for the computers should be unnecessary to use the "Smart Functions" of the TV.
Two weeks in and having exactly the same problems with Vizio 40" M class TV. Several calls to Vizio tech support and still no resolution. They keep telling me to turn off file sharing, but I've never had file sharing turned on. Last night they told me that any device on my network could be attempting to send files to the TV and that it "overwhelms" the TV causing it to freeze up. I am going to return it (to Walmart) and get a Samsung or Sony.
Have the same issue where the remote freezes upon turn on for a minute or two on my M422i-B1.
It clearly is related to Vizio TV's not being able to handle other network-attached devices on your network being visible as stated above. It appears to even recognize and browse DVR's which of course it cannot play from. On this set you can open media and see what it is seeing. It is not some kind of incompatibility with a router or something.
Anyway, I was wondering if anyone has access to the service menu on this TV? Of course you can find methods to get INTO the menu online but I don't muck around in Service Menus without screen snips and instructions on how to get in and out.
Anyway, a service menu settings that allows you to turn off "media" or the ability to play files on network attached devices would probably solve the issue. Otherwise you just have to leave it disconnected from the internet to get remote access immediately.
This has been a problem for a long time with their sets. I just like the quality and price point. However this is annoying and should be fixed.
It's been suggested on a thread on Consumer Reports to disable networking on the TV altogether and instead use a Roku or other wireless streaming media device, but come on, Vizio! you advertise this as a Smart TV with networking. Fix your product!
Yes, Vizio should fix it. Until a big stink is made by a reviewer who says a Vizio TV freezes up when put on a network, I don't think it is going to be fixed. It is across models and years but not enough people return TV's or complain.
