Tv has all snow, no picture, no sound. Cable works fine elsewher

call the company or reset the cable box if you have one or make sure it is the right remote

Check the input cable to dish box for firmness and the orientation of the dish.

Have the cable company correct your wiring

This universal remote (or the TV's original remote) should have an Input button, which allows you to switch the various inputs available on the TV (such as HDMI, composite, over-the-air, cable, etc). You can try hitting Input until you see a picture, but be sure to turn on any devices connected such as set top boxes, DVD players, etc.

As far as I know, my Go Video machine when there was no box involved...

The cable came from the wall to the IN of the Go Video box. Then another cable coming from the OUT of the video box and to the IN to the TV. TV should be on channel 3. As far as I can remember, I don't need to push the TV/VCR button, but instead, have to channel down to below channel 2 on the TV to the LINE/INPUT selection. Once you go there, and the Go-Video machine is on, you should be able to see a clear picture.

You'll push the TV/VCR button if you want to toggle back and forth from the VCR picture to the TV picture (which will be technically blank since it's on the 'line input selection.)

Hope that helps.

The input may have been changed, press the input button on the remote or tv until you get the picture back.

you have to take the remote, find the input button, push the input button untill your picture comes back, you should see the input go from cable/antenna, to vid 1--vid2---vid3---if pushing the button a couple of times dont change it, you will have to hit the input button, then arrow down, and select the nexy one, do that untill you find the picture

code TV/ 0156 or TV/ 1256 (or TV/ 10156 or TV/ 11256

After fooling around with all of the buttons, and disconnecting the power to the TV, it occured to me that it may be the Comcast digital cable box. I unplugged the cable box for a few minutes, plugged it back in and the TV works just fine!

I had this happen with mine also and finally determined the A/B speaker. That is my only experience.
