I was trying to connect the TV to my computer to look at some pictures. When it said Input select, I tried looking for one that would show the pictures. I couldn't find any. Now my TV has sound but no picture.
If you are running Windows XP. then go on the desktop. right click it. click properties. click settings. then it should show two monitors. click monitor 2. and click the checkbox that says "extend my windows desktop onto this monitor" and you should be all set.

You need to use audio cables. Connect two red and white audio cables from the output on the HD box to the relative input at the back of TV (nr.4 in picture below). The best way to connect the HD box is by using component cables, that are the red-green and blue trio of cables, plus a white and red audio cables.
Once you have the five cables, connect them to the output at the back of the Direct TV box, and then connect the other end of the cable to either group of connectors 6, or to one of the columns in connector 7. Do connection with box and TV power off. After re-applying power use the source-input selector on remote to select the source from Direct TV box.
Find the button that relates to the input you want to view. IE "video" "composite" "s-video"
Or simply try any of the input buttons until the picture returns.
Also try simply hitting the VGA button again.
If none of that works, please let me know the model number of the tv and the input sources you are trying to view.
Blue screens are a strong hint that your tv isn't picking up an image. Check to see if you have a firm connection on both your tv and your input device (cable box/ dvd player). You may want to disconnect and reconnect fully. Also attempt selecting other inputs. If you only have trouble with that one input, then you have a loose internal connection. Also make sure that your TV can display an image by trying to use the on screen controls.
If you have sound it means that the tv is in aux/video mode.
Now make sure that the video output of the vcr is connected to the same aux/video input that has the sound connected to. i.e input 1 or 2 .
Also you want to try and switch with another cable to make sure that the cable you are using now is o.k.
Another way to try the tv input would be to connect something else in that input(cable box ,dvd ,video game etc,)
Try it and let me know.
Try using the video inputs
What to do if you have an all snowy picture (blue screen or the TV displays unusable signal-no signal or no sync)
1 – If you are using a digital cable box or satellite receiver (make sure it’s on) and be sure your TV is set for either CH3 or CH4 (which ever you usually view it on). If you usually view it through video inputs (video1 or 2 etc.) make sure the appropriate input is selected.
If you still don’t get a signal see if you get picture using the DVD or VCR (if available) if you do than plug the satellite or Dig. Box temporarily into the place of the DVD (unplug DVD) you may have to use some A/V cables (RCA yel./red/wht like the ones on the DVD) to hook to the tv from the sat./dig. box. If you get a signal then the sat./dig box is ok. If not the Sat./dig box is not sending a signal and is either defective or needs to be rebooted (unplug wait 5 min try again).
2 – If you are using standard cable or antenna (source) if possible check that the source is good by connecting to another TV. Otherwise try running the source into a VCR and then out to the TV using video inputs (RCA yel./red/wht like the ones on the DVD) and then selecting the appropriate input. Try seeing if the VCR plays using standard CH3 (or CH4)
If the VCR plays on video input but not when connected to CH3 (CH4) then the tuner of the TV may be defective – see if you can use the VCR to change channel using the VCR remote. Be sure to vote/rate me if this helped Thanks!
Perhaps 2 things. Does TV get a picture without DVD connected? If so I would bet you have a faulty connection in your signal board where the in jacks are at the back of the TV . Check to make sure cable from DVD are not bad, I have used cables before and got a false positive. Try turning and spinning the jacks once you have a picture.Make sure your signal board is firmly pressed into its slot on the signal board chassis. Thats it for now. Good luck.
No sir, there is not such switch in menu to change input from S video to HDMI or something. Here is one suggestion, Use 3 RCA pins cable (Audio L/R & Video) to connect both unit and check/ remember TV input and same should be selected in TV menu.
I strongly doubt it's the lamp assy since you can actually see the blue screen. If the lamp failed, you would not see anything on the screen. This blue screen indicates to me that either the tuner is no longer decoding the signal, in improper input has been selected (ie: input 1 is selected while actual signal is on composite 1), or something of that nature. If you are getting audio then the input is selected properly but the video decoder has failed.
If your cable signal is going through a VCR or DVD, disconnect it from there and go directly to the TV (ie: bypass the VCR/DVD). If your picture comes back, there's some kind of problem with your VCR/DVD player.
If you have multiple inputs, try connecting an input signal to another input (ie: video 1, or aux from a dvd player) and see if you get a picture there. If you do get a picture, the whatever input you're currently using has malfunctioned.
First of all, is your blue "HD" light lit up on the front of your Uverse box?
If yes, then you're in HD
If No, you need to check your connections from Box to TV
1.Those Red-Blue-Green cables are for video only, they don't carry sound and shouldn't be connected to audio outs. Audio needs a seperate cable. Make sure your Red isn't on the audio out which is also red. Make sure your blue and green aren't switched with each other either. Check that at both ends.
2. Try an HDMI cable. It will carry audio and video together and it's one cord instead of 5.
3. What brand/model of TV is it? Is it an older projection TV? The HD tuner might be shot. The individual color tubes commonly fail after a few years.
4. Are you selecting 720p or 1080i from your TV's menu or from the Uverse menu? You'll need to set it through the Uverse box, not the TV.
5.Follow -Menu -Settings -Aspect Ratio to change to 720 or 1080. This should start an autotest which will scramble your picture for about 5 seconds, then bring you back to a menu asking you to keep settings or revert back settings. If you never see that question pop up, then your TV isn't supporting the HD, and you settings will be rolled back automatically. If the question does pop up and you can read it, select "keep settings" and press OK. Your blue HD light should come on the front of the box now.
Make sure you are selecting the correct input on your TV for your TV tuner, sat or cable box.
There are three ways to do this:
1. With the tuner or cable box turned on (you can do that manually or with its remote) use the TV's remote to cycle through all the inputs, until you find the correct one and take note of the name of the input that appears on screen, or
2. Look at the back of the TV and see where it is connected. It will say the name of the input, such as "HDMI1" or "AV2," etc. Then select that input on your TV with the cable or sat tuner turned on, if you have one.
Consult your TV's owner's manual, which will give more information on hookup and selection.
