Vizio TV Problem

Has anyone experienced a problem with Vizio tv's and U-Verse?  I keep getting intermittent AT&T messages saying a loss of video signal and to disconnect and reconnect the HDMI cable and to unplug and replug the cable box.  In doing this it does not resolve the issue.  I have conected other tv's to this cable box and they do not experience the same problem.  I have moved the Vizio to other AT&T cable boxes within my home and get the same error.  Because the error seems to follow the tv I assumed the tv was the problem.  After having the tv repaired only to get the same error Vizio claims the problem is the AT&T service.  They say because the error message I get is an AT&T message it must be the AT&T service.   

 

Any thoughts?

If you cannot get the TV to work with the HDMI interface, the simplest solution is to use the component interface. This uses 3 RCA jack/plugs for video & 2 for audio. Be sure to connect the same jacks on the STB with those on the TV.

Ypu will find thepicture quality to be the same.

I have had a similar problem, except mine is a 10 minute "warm up" issue. My Vizio appears to have a problem "catching up" with the HDMI when i first turn everything on. There is lots of digital snow and flickering of picture before the tv finally catches up with the box and the pic and sound are solid. I have a second tv hooked up to my U verse box with regular coax (i live alone so i only need one box) and sometimes i get that error. I just usually have to turn my Vizio off first before i turn the regular tv on. When i have the Vizio hooked up with a coax cable i have no issues what so ever. I havent gotten component cables because the HDMI looks so good with the Uverse! I can wait the 10 mins to warm up!

craigrussell100 -

 

If you want to keep HDMI you can try a splitter like the one in this link -

 

http://www.amazon.com/HDMI-1-Out-Auto-SwitchCable/dp/B0018DQYQ2/ref=sr_1_3ie=UTF8&qid=1302660018&sr=...

 

Some people have reported success with this. While this is not seperately powered, it is not totally passive. It seems to work by isolating the TV from the STB. 

 

If you search for one do not get one that is totaly passive. Also, this one splits one TV connection to multiple devices. You do not want one that splits one device to many TVs..

FYI, the solution that has worked for lots of people who were having handshake issues with their tvs and the stbs is, while thte tv and stb are still turned on unplug the hdmi cable from the stb.  Press and hold the power button until the lights blink.  After 5 minutes reconnect the hdmi cable to the stb.  If that doesn't work then using component cables to connect those two devices will definitely resolve the handshake issue.

I tried this but when I use the component cables it steps down from 1080 to 480.  When I set the tv input to the component setting and keep the HDMI cable plugged in I get 1080 but still get the error message.  As soon as I unplug the HDMI cable it steps the tv down to 480.  While it's watchable at 480 it defeats the purpose of buying a 1080 tv.

My problem is just the opposite.  When the tv is first turned on it's perfect, as the tv warms up the errors start and get more frequent the longer the tv is on.

Have you gone in and set the stb to match the hd setting on your tv? What is the normal hd setting of your tv?  Is it 1080p or i?

Component cables are fully capable of 1080i.  Remember that component cables are different from composite cables.

 

 

Composite (older) cables are 3x RCA connectors, colored Red-White-Yellow, with 1x connector for video (yellow) and 2 connectors for audio (Red = right, White = left).  Composite cables carry a maximum resolution of 480i.

 

Component cables are 3x RCA connectors, colored Red-Green-Blue, with all 3 connectors used for video.  These cables can carry a maximum resolution of 1080i.  In addition to these, you need some type of audio connection.  You can either use 2x RCA cables (Red=right, White=left) for analog audio, or you can use a TosLink optical cable for 2.0 and 5.1 digital audio.

 

Once you connect up the component cables (unplug the HDMI cable), you will need to go into Menu -> Options -> System Options -> Aspect Ratio and reset the output resolution to 1080i.

I thought about describing the color of the component cables but I thought the OP already knew that.  Good job posting that SJ.

I'm trying to hook my box up to my Vizio. I have it plugged into the cable port (no HD). There is no yellow port on the TV for the video composite cable. No matter how I hook it up (haven't tried HEMINGWAY cable ad I don't have HD service) I get No Signal...any ideas?

Look at the component cable connection (red/blue/green) I believe that the green cable connection is shared with the composite connection.

 

Also, if you have an HDTV seriously consider connecting your STB to the TV via HDMI and adding in the HD service.the picture quality has a drastic improvment over standard def.

Original post is old, but someone else will look this up and see this reply.  I too had that problem several times a day since the first day of my install.  Had a new box and cable put in, and still had the problem.  I read online about changing away from an HDMI cable.  I told ATT that they needed to provide me with the cable, seeing as how from all of the posts, that they know it's an issue.   However, I found the original VIZIO cable that came with the TV.  I took ATT's cable off, and put that cable on.  Knock on wood.............I haven't had a problem since then.

I had the same problem with a Vizio TV. Worked great with Comcast and various DVD and Blu Ray players, but no signal every time the TV was turned off and on when connected to the U Verse Cisco STB. Unplugging the HDMI cable from the STB and plugging it back in usually restored the connection.
Here's what fixed my problem.
I used the shortest HDMI cable I could to connect the STB to the TV, in this case a 2' cable.
The 10' cable the technician used to connect the TV doesn't work, and neither did the better quality 6' cable I tried. The 2' cable works every time without a problem.
What does this mean?
The problem is probably that the HDMI output from the Cisco STB is lower than most other devices, and the Visio TV is probably pickier than some others about the quality of the HDMI signal it needs to lock on and display picture and sound. A shorter cable has less capacitance, which allows for a cleaner signal to reach the TV input. All of the cables tried worked fine when used in my other TV setup (an LG).
AND, the Vizio has worked fine with the Comcast STB and various other devices.
I tried all the other fixes I saw in these forums, to no avail.
The short cable fixes my problem, and may work for you as well.
