Rolling lines are color bars that scroll from the top of the screen to the bottom and generally represent a malfunction of one or more raster patterns. The TV picture is made up of scanning lines; however yours has an additional color line moving in between the normal synchronization process. Various electronic elements such as resistors, capacitors, diodes, and resistors, may change in value over time. Changes can make various electronic functions change from a normal routine to an abnormal routine such as you are seeing on the TV. If the problem is too difficult to put up with, you can have the mainboard or video RGB projection tubes replaced if found defective by a professional technician. Other than that, you cannot fix the problem yourself.
