Question about Vizio VF551XVT 55 in. HDTV

3 Answers

I have a VIZIO LED/LCD VF551XVT hooked up to a motorola HD DVR with a HDMI cable. When I switch from standard Def to High Def channels I lose the sound. If I turn the TV off/on the sound returns but if I flip HD channels after that the sound will go out agian after 4-5 channels. Never loses sound on SD just on HD channels. Not the same channels, no pattern present appears to be random.Have tried new HDMI cable, returned TV and got new one! Tried all the HDMI ports. Nothing helps. Component cable hook ups works, no problems...but lower quality picture. Have tried every setting on TV and cable box and talks with several techs. No one has an answer!

I have the same set, same problem with one of my MOTOROLA boxes, but not with another. I have a SONY TV that works fine with this new MOTO box, but the new VIZIO does not. The audio is coming through the HDMI cable just fine, and the fact that it works when you cycle power on your TV means it's the SYNC between the TV and the BOX. I have the identical problem and am taking back the MOTO box for another one. I spoke to VIZIO for about 45 minutes trying different things. They think it's the MOTOROLA box, COX (my cable company) thinks it's this particular box, who knows.

I have this same problem, when I turn on the TV there is no sound. I have cycled through HDMI and off air signal and comp 1, all with no sound. The only way I can get it back is to go in to the menu and change the sound to fixed from variable, then it will pop back on. Since the lack off sound happens with digital tuner on local channel I know it is the TV and not my Direct TV box.

A LOT of HDMI formats DO NOT push Audio through the HDMI, they only use it for Video, so you must run your sound separate usually via the RED & WHITE Audio out jacks.

Picture is not clear, how do I fix it?


I assume that you are dissatisfied with the quality of the picture on the HDTV. Are you feeding it with an HD signal. First, it must be an HD source, either over the air HD or a cable channel in HD (not all "digital" signals are HD signals). Second, you must be sending it with the proper cable, either HDMI or at the very least RGB Component Cables (not composit video).

It is quite common to see standard definition on HDTV's actually look worse than on standard def sets. The reason is the extra pixles availble on the HDTV make you realize how low of resolution the standard def signal is. Instead of it just being fuzzy or unclear, it will actually look bad.

Recording HD channels


well you would need to hook up cable box to dvd recorder. the only draw back first off is one you cannot get hd onto a dvd. you can down scale and it will seem a little cleaner than standard def but of coarse it will never be high def. I'm not to familiar with the motorola boxes but if they offer dvr's in your area i would suggestgetting one you can record all channels then afterwards transfer them to a outside device. but as i said before high def cannot fit onto a dvd unless you plan to copy one movie to 6-7 disc. Just keep in mind a standard high def channelcan only fit 2 max on one freq due to the amount of data transfer as opposed to 10 to 12 standard def digital channels

How to get a high definition Picture??


Hi, first of all you need a high definition source. I'm not sure if your cable box is HD but lets take it as an example. The component leads which you are using isn't 'true' HD video quality, what you need is a hdmi cable from your source to your TV.

Your cable box maybe HD with a HDMI output, if it is then you need the lead to come out of the cable box into your tv's HDMI input using a HDMI lead. Then you switch your TV's source to the HDMI input and it then should be producing a HD quality picture, but to truly get the full HD experience you may want to subscripe to a HD channel or purchase a blueray player becasue most cable TV channels are upscaled to HD and the definition is not as good as on a blue ray disc or a true HD channel.

So in conclusion the cable and input you are using is not designed for HD input. I believe your TV is HD, check for HDMI inputs or DVI inputs.

Hope this explains your problem

Full screen view


in order to get the full HD experience you should be using HDMI cables. if you're using the white/red/yellow cables then your HD channels will not broadcast in full HD and you'll be stuck with the annoying black things around your screen
