Rolling horizontal lines on tv screen

It sounds like electrical interference from the converter box. Do you have the box sitting on top of or right under the TV? If so, move the box away at least several inches. You may need a longer cable to do this.

It could also be that the TV isn't syncing properly to the box. In that case the only solution is to adjust your TV's horizontal and vertical controls. If they're not on the front of the TV or the remote, look on the back.

I have the same problem...

Good: Connect the antenna to the converter box where it says antenna/in. Connect the coax cable to where it says to tv/out on the converter box. Connect this cable to the coax/rf input on the television. Plug in and turn on the converter box and the television. Make sure the television is on channel 3 and follow the setup process that pops up on the screen.

Better: Connect RCA cables to the converter box where the yellow red and white holes are. Connect them to an RCA input on your television. If you don't have a red hole on the television that's ok, just connect yellow and white and leave the red plug dangling. Connect the antenna to the converter box where it says antenna/in. Plug in everything and turn everything on. Press the video/input/source button until you have located the setup screen for the converter box and follow the directions on the screen.

The converter box simply installs between your Antenna and your TV (tune to channel 3 or 4) http://digitaltips.org/docs/FlosTips.pdf

A dvd that does not Record is designed to simple install into a separate Input connection on the TV (do you have a VCR/DVD combo?)

Do you have an older TV with only one "Input" for a cable connection? (no Red/Yellow/White Inputs) if yes you may need to take a trip to Radio Shack

It ended up being the Verizon Fios box. We recycled it and the picture stopped rolling. Thank you for being here to help. If I have any future questions, I'll definitely use your site.

Is this a LCD TV? IF it is it could be something on the video processing board. Let me know the model # and well will go from there. Thank you Jay

Turned on TV and all that shows up on the screen is horizontal colored lines
