start with ctrl+n for new image
and choose 5x5px and transparent, as shown below


zoom in as far as you get, right click the "brush tool"and select the "pencil tool"

make sure you have a 1px size brush, usually its preset, so if you never tuched it, dont worry about it.

now go to Edit>Define Pattern


choose a name, like "scanlines"

then click "OK"

to load your pattern, go Layer>New Fill Layer>Pattern

now, you get a new box up, klick "ok" or play around with the settings, but for the first time, just click "ok".
Do the same with the seccond box.

now, change "Opacity" to 10-15%
