My tv has several white horizontal lines running across the top of the tv screen the tv brand is an Insignia SDTV and its an older tv what can be done to remove these lines?

This is a retrace blanking problem. Probably, the Vg2 voltage is too high, so the cut-off point from the picture tube is not correct. Try to lower this voltage. On most common flyback trafo's it is the lower adjusting screw (plastic kind of button) which is used to set the Vg2 voltage. Turn it a bit CCW until the white lines disappear.

Visual transparent lines at top of picture

You have a vertical output circuit problem. This was common for Philips' sets. Have a repair shop check it out. Should not be too expensive to repair.

White Horizontal Lines @ the top of my 32" Sharp Black Box TV

This Problem is usually caused by Leaky Capacitors in Vertical deflection circuit.
If you are handy with electronics,
Get a can of FREEZE Aerosol.
Open the Back Cover.
Put a mirror in front of TV.
Locate the Vertical Circuit.
Turn the TV on.
Spray FREEZE on top of individual Capacitor to see if it corrects the problem.
If it does, Replace that Capacitor.
