White lines equally spaced 1" apart.


This is probably caused by the small signal board. It controls and decodes the picture information before it is sent to the display panel. It can be fixed by a quailified technician and if you contact philips (this is who makes magnavox) they will tell you the closest certified technician. Hope this helps.
