| Step #1: New Image Start a new transparent document that is 2 pixels high and 1 pixel wide to create a horizontal scan lines as shown below. To create vertical scan lines (for variation) create a document that is 1 pixel high and 2 pixels wide.  Step #2: Creating a Pattern After you've got your new image, use the ZOOM tool and zoom in on your pixels. Select one of the two pixels and fill it with black or any other color. Be sure to leave the other pixel alone, it needs to remain transparent for the effect to work correctly. Step #3: Defining the Pattern Select the entire image using SELECT --> ALL (CTRL - A) Now you need to define the pattern. Click the EDIT menu then Define Pattern. Name your new pattern something you'll remember. Like HORIZONTAL Scan line - Although it is usually easy to find later on since it looks like two huge pixels (one black and one transparent). Step #4: Applying your scan line pattern Apply your new pattern to any image or piece of interface by loading a new or existing image Create a selection around the area you want filled with scanlines, create a new layer and use the EDIT menu --> FILL --> Content = pattern --> Select your new HORIZONTAL Scanline pattern and hit OK as shown below: 
Conclusion: Other Examples Below is a photograph with a basic scan lined pattern applied to get a general television effect. For this image, I selected the entire image and filled a new layer with the pattern.   I hope you find this tutorial useful. Please contact us if you are having any problems!
