Magnet came in contact blue green and red color

Every time you turn on a color TV, a degaussing circuit tries to neutralize magnetic fields on the picture tube face that can cause distorted colors. That degaussing circuit isn't strong enough to clear up the field left by direct contact with a magnet. You need an external degaussing ring to clear up the funny colors. You can see what one looks like here. You might be able to find one for sale on eBay or borrow one from someone in the TV service business. Or you can take the TV to a shop where they can degauss it for you for a small charge. Just be aware there's a chance the picture tube may have been damaged if the magnet was very strong and was in contact with the tube for any length of time. A thin metal screen called the shadow mask is behind the tube face, and if that was warped by the magnet then the colors will never line up correctly again. If this has happened, even after degaussing the colors will still be wrong. But you won't know until you try. Good luck, and thanks for using Fixya!

Screen goes green with white vertical lines

I think either your red and blue filaments are not fully intact causing the green to take over or you have other electronics like subwoofers too close to your tv.

Try degaussing your tv, it might have a degaus button at the back or check the menu.

If you've tried those things without luck, respond with more details.

Hope that helped.

Black screen with a line of the picture running

The vertical sweep generator is dead. The circuit that controls the lines being drawn from top to bottom has malfunctioned or died. This not something you can fix, you will need a professional.

Insignia 32" TV Thin line across screen 1-2" from top

This is usually caused by bad capacitors in the vertical circuit. If you have an electronics background you should be able to find the defective ones with an ESR tester .

Thin horizonal line in middle on dark screen

The several thin white lines at the top of the screen is the warning that the vertical output IC is not getting the boost voltage it needs to run correctly. The IC cannot operate for long like that and shorts out inside, which is when the vertical collapses altogether and you get the thin white line through the center of the screen. The good news for your son is that he had nothing to do with that, and it has nothing to do with the cable F connector. The set needs to be serviced by an experienced tech who will restore the boost supply and replace the vertical output IC, and when I do that I charge $75 but techs in your area will vary, so be sure to ask around.

Horizontal 'pinstripe' lines on all channels

sound like the screen control on the flyback is set just a little too high. the flyback has the red wire attached to the tube. the flyback has 2 small adjustable controls. if you look close enough 1 is marked focus & on is screen. turn the screen slightly to the left & look at your picture. the screen is like a master brightness & if it's up too high you will see what is called retrace lines. good luck.
