TV not responding well to IR remote commands
The Vizio Television SV472XVT responds intermittently to remote commands for mute and volume yet seems to respond ok for VIA (menu for apps) and TV settings. I have the original Vizio TV remote, a Comcast X1 remote and a Harmony remote and all give the same results so it is the TV that is the problem. I have unplugged the TV and restarted it. I haven't reset to factory defaults because the picture is calibrated and very good. Input is by HDMI cable from an AVR receiver. The problem started about a month ago and has become worse but the sound buttons on the TV work fine. Seems like a firmware problem to me. Will a reset to factory defaults affect this? Any other ideas? thanks.
Is this a good question?

I want to add an update for checking your remotes. If the remote is IR (not paired using bluetooth) you can point your phone or tablet camera at it and press any button on the remote. You should be able to see the IR on the phone screen as a pulsing or steady light. This also works for Harmony remotes that use a hub, just point the camera at the hub instead of the remote. This way you can check a remote to make sure it is functioning. Ron

Thanks! Same Problem
Have a Vizio 42" XVT3D424SV and have two Vizio keyboard VUR10 remotes. So the other day the VUR10 I had been using regularly stopped working. After having tried the Vizio Support remote reset procedure which included replacing the batteries and removing plug from outlet a few times with both remotes had limited to no success. One VUR10 stayed totally dead the other VUR10 would only power on the TV - no other remote finction worked. Called Vizio support who protocol is first to suspect the remote is the problem. However, since I tried unsuccessfully to program a Comcast universal remote I have concluded it is the TV IR sensor and not the remote. Vizio support did provide this link to VizParts for IR Sensor part #: 3647-0012-0189 however, they only had re-certified not new part. This IR senor seems to be in short supply: I have ordered a new part from ebay we will see if new and if it works.

I may be our of sequence or redundant but to follow up on Whole Witt's post regarding mobile phones, tablets, etc... the Play Store has a "Peel Smart Remote" app for android (not sure on iPhone) that can duplicate a remote (if the phone is IR capable), which is another way of isolating whether original/replacement TV remote is operational/faulty... I apologize if this point has already been established... and still grateful Whole Witt got me looking at my IR board (which was bad, and replaced easily at low cost)... odd that it appears there are quite a few apparent issues with Vizio IR boards--but I am sure they sell millions of TVs and my scale/scope of the issue is likely very incomplete...

I have a Vizio E32H-C1. The IR is NOT bad, although Vizios "go to" is to sell you a ton of remotes. When the TV does respond it is very slugglish. I have done the "power cycle" and have managed to to the reset thru the TV's menu. The TV for the most part is non-responsive. It is only 2 years old. This is isn't the first time this TV has done this, although other times a power cycle has resolved the issues. Multiple remotes have been used with the same result extremely sluggish response. It take about 15 minutes to raise the volume 2 clicks and the is not a manual button on this TV for audio, only power. Talking to Vizio is worthless.
