I have 1 TV that has no picture at all. Just snow

I have 4 TV's in my home. In one of my back bedrooms the TV has no picture. Not even a blue screen just coming up "snow". I have tried reseting the unit with no luck, Everything is plugged in properly. Very confused as it only effects 1 TV.

How is the TV connected to the receiver?  HDMI?  Trace the cable from the receiver to the TV.  Find out what input it's on and change the TV to that input and it will work.  Sounds like your TV input somehow got changed.

 

It has worked before, correct?  Just quit working?

 

Here is an esupport article that shows how to connect your TV with pictures and all: http://www.att.com/support_media/images/pdf/uverse/att_uverse_setup.pdf

It was working fine with no problems until this morning. I was watching some shows on that same TV last night.

Re: I have 1 TV that has no picture at all. Just snow

There are some tvs that when power is lost, (electrical storm, outage) when power is restored and turn on set reverts back to TV MODE, if normal connection from receiver to tv is coax, make sure tv is on channel 3. If receiver is not coax but AV, component or HDMI, use tv remote to change input (source) or uverse remote, depress tv/video button (upper right side) to cycle thru inputs till correct feed is found as recommended by BeeBeeSA.

Re: I have 1 TV that has no picture at all. Just snow

snopea123 - BB & MT give good advice. The symptoms you describe can only be caused by a mis-setting on the TV or a failure of the TV, the connecting cable/connection or the STB (because the STB always outputs something).

Another good technique is to swap components. After trying to find the right input, swap the connecting cable with another, then the STB, Then the TV.

Thank you so, so much! This worked after I had tried a couple of other solutions suggested on this forum. I now have my TV back! Have a blessed, productive day!

Re: I have 1 TV that has no picture at all. Just snow

I have the same problem.  1 tv in my house is nothing but snow.  No sound, and the remote won't do anything.  I was watching this tv last night and now when I turned it on, nothing but snow. You said, thanks it worked and now your tv is back.  Mind if I ask what it was that worked?  I've checked all the connections and they all seem to be ok and  we've had no storms. Any help would be appreciated

Re: I have 1 TV that has no picture at all. Just snow

anglbabe43, your issue (snow no sound, no remote affecting TV) sounds as if your TV input has changed

Using the TV remote (not uverse remote) find the source or input button and slowly change the selection till a uverse screen appears. If do not have TV remote, look for button on TV that would allow same operation of change.

Snow generally means your on a TV channel input, depending on cable used between receiver and TV...
Coax cable, TV input,channel 3 required.
Red/white/yellow,, A/V aka as video input required.
5 cable requires component selection
May be S video
HDMI cable requires HDMI selection

Depending on type of TV may have more than one of each choice.
TV, video 1, video 2, component 1, component 2, HDMI 1, HDMI 2, HDMI 3....

The ONLY way to clear my problem (while watching TV, my screen suddenly goes to snow) is to power reset the AT&T receiver.  This problem happens about once a week. I now have a new TV and a different HDMI cable and it is still happening.

ruhrow - The HDMI interface is failing. Not a physical failure. A software failure. Switch to component cables - http://www.amazon.com/Mediabridge-Component-Video-Cable-Audio/dp/B001ID829O/ref=pd_rhf_dp_shvl1

Re: I have 1 TV that has no picture at all. Just snow

What would be the fix for the software failure? Isn't the software failure in the receiver since I had the same problem with my prior TV? This problem just arose in the last month or so after 1 year of reliable service. I ask because I have no component cables. Thanks

Re: I have 1 TV that has no picture at all. Just snow

ruhrow - Perhaps incompatibility is a better word. Something does not mesh between the two causing loss of service. HDMI is very flaky. Your logic is valid for most case, but not HDMI.

There was a recent poster that solved their HDMI problem with a shorter cable. Can you try that?

You do not have a component cable or you do not have component jacks on the TV?? If no jacks, you could try a converter component to HDMI.

aviewer: I have noticed that HDMI on the DVR box, itself can be an issue.  I have one more HD set, with HDMI and it, on a non-DVR box, is fine.  Once or twice a week, the picture on the DVR set will go black and the TV's signal status will pop up, with the resolution flashing.  Power cycling the TV, usually fixes it.  Once in a while, I will get a long winded U-Verse HDCP error box with like 7 possible issues.  Power cycling the TV or the DVR will fix.  Sounds like a firmware issue with the DVR's.

 

You know what the rub is?  This error always happens at a key point in a show, movie or game!  Smiley Very Happy

Re: I have 1 TV that has no picture at all. Just snow

dhascall - I believe you have two separate issues.

The first is the black screen & TV error message. I believe this is a loss of HDCP from the TV, through the HDMI to the STB. It turns off the U-verse video with no explanation (Explanation would be good) I think the only solid solution is to replace the HDMI with component cables that are a one way interface. More recently, a poster reported success with a shorter HDMI cable. This may work for you, or not.

The second is the list from U-verse on the blue screen saying lack of signal and suggesting things to do. ThIs would not be HDCP related. It is a momentary loss of u-verse "DSL" signal. Could be a bad connection or the RG or DVR going bad. If it hardly ever happens, I just wait a few minutes & it comes back itself. If it is problematic, call for remote test. Probably start with a new RG. If you have COAX cable check to be sure you have compression fittings & the connections are tight.

Please keep in touch on your efforts. I hope you find relief quickly.

Re: I have 1 TV that has no picture at all. Just snow

 When I turn on the TV, I get the same thing. I have to reboot the TV to get the signal. I have had this service for less than a month and this has happened twice. Seriously reconsidering canceling AT&T TV. Not cool.
