Colored lines down the tv

What causes vertical colored lines on a TV screen? When a TV is showing vertical colored lines, a loose wire cable in the TV might be the cause. If you knock on the back of the TV, the vertical colored lines MAY disappear temporarily. This is a sign that a cable is loose or the T-Con board is faulty.

It sounds that the color mask inside the picture tube have been displaced due to hard shock. If so, it is irrepariable.

Nothing you can do about that...get used to it or change the TV.
It's a defect in the panel that can't be reliably fixed.

turn the center dial ( for green) down slightly then turn the other two the red and the blue up slightly to get the best screen without a dominate color screen.

You've got a bad display panel.Not worth repairing.

The only way to do that is by eye. To Adjust the screen controls the best thing to do is turn them all down then slowly adjust one up until you get retrace lines (arched lines across the tv) then turn it down until the lines re not visible then go about 1/4 turn more, repeat this for the 2 remaining colors, after that its just done to eye for the best color. if you are still having trouble getting the color right you can go in the menu to the video settings and turn the color all the way down then you will have a black and white picture and you can adjust for a perfect black and white picture then turn the color back up in the menu.
As for the focus controls its best done by covering 2 of the tubes so you only have one color on the screen then adjusting to the best looking focus for that color. then repeat this for the other 2 tubes.
If you need more help or clarification please let me know

CHECK VALUE OF RESISTORS IN CRT BOARD,,,,AND THE 3 TRANSISTORS COLOR DRIVERS ....THATS AUTO SHUT DOWN FOR OVER VOLTAGE....DO YOU SEE RETRACE LINES BEFORE SHUTDOWN?IF YES TRY TO LOWER DOWN SCREEN FIRST ON THE FLYBACK TO SEE IF ITS GOING TO SHUTDOWN.....

I followed GuestUser/ Slinteriors advice and I fixed it. Open the front of the TV and there are 6 little nobs in the front. The botton 3 are what you need to adjust. from left to right the color controls are BLUE, RED GREEN. For the blue lines, slightly (I really mean very slightly) turn the botton left nob clockwise (right).

well it all depends on where the tv is located to, if it is in a room with little or no light( windows, lamps) you will want you brightness to be a lil lighter hince not makin the picture as dark, and vise versa for light rooms, u'll wanna turn the brightness down a lil bit to accomidate this room, as for the others i'd say a lil over 50% on them, thats how my office tv is set up, hope this helps, jason

caution whenever you see horizontal line please reduce brightness of your tv for safety of crt. your problem in vertical section only mostly due to loose contact in connector,print or loose components.
