Ur tv have a problems known as a convergence picture problems,it is dead.The tv have R,G,B colors lines mis alignments,tv have colors shadows pictures or 3D pictures look alike?Yes,than the tv have a dead tv convergence board.The tv convergence board must require changes 2 STK convergence ICS and some or all of it resistors too.After the tv convergence board is fixed,the tv convergence picture problems will be solved.The tv shop,will cost u like $300-350 for parts and labors.
Your description of the problem sounds like a convergence issue. You more than likely have lost the convergence ICs. They will need to be replaced and the convergence will have to be set. The green beam should not move. It is the standard which the red and green are moved to overlap. Since you have bow at the top and bottom I would replace the convergence ICs. I have a tip at http://www.fixya.com/support/r4220499-change_projection_tv_convergence_ics which explains the problem, how to replace the parts and where to get the replacement parts.
Thanks for using FixYa and for the great rating. Great ratings will keep the experts helping to solve problems. Thank you.

Your convergence amplifier has failed.
There are a few things that usually cause that in that particular chassis design, the most likely one being that you have lost part of the power supply to the convergence amplifier power supply board.
You may be able to repair it yourself if you're good at soldering, and dis-assembly / re-assembly.
Look for a 400ma fuse that's opened near the FBT, and re-solder all the connections in that area. Also check to see if any diodes have shorted around it too.
The tv has 2 focus adjustments for each tube, mechanical and electrical.
1. Mechanical focus is set by looking at screen from back (through inspection plate on back of most samsungs) and rotating the lens assembly on CRT. loosen wing nut and turn lens assembly to go through focus and back to best position.
Put convergence pattern on screen and manually misadjust bottom red and green lines convergence so they can be seen through inspection hole.
With back cover of TV off you can usually reach your hand up beside the lens assembly to loosen the wing nut then rotate to adjust. Green is in the middle. The focus will be obvious when you rotate and look
When you are finished make sure the foam dust protector is not over any of the lens assemblies and the wing nut is tight.
2. Electrical focus - located at front of unit. the front grille/speaker cover is removed and maybe a cover over the front crt inspection hole.
In the inspection hole there is a black plastic "Focus/screen adjust Assembly" with 2 rows of 3 controls.
One row is focus and the other is screen. The middle controls are for green with R/B on either side. Usually the controls are labelled as "focus" and "screen". You want to adjust the focus controls, one for each color. Look for the focus or screen label imprinted in the plastic. Don't play with the screen settings.
With the same misadjusted convergence pattern you can see a red, blue and green line. Adjust green focus and watch green line for best focus. Do same for other 2.
Screen adjustments are very exact and delicate. The easiest way to deal with them is to turn color off in Customer adjust menu. Put any color tone adjustments in the middle (low, med, high, put at med).
You should have a b/w picture if there are no crt or other color related faults. If it is close to B/W leave screens alone.
If the pix is too green, then the green screen setting must be reduced a small amount. Do not play with these adjustments as most TV repairrers have a difficult time adjusting them.
If focus adjustments don't help then focus control or CRT may be defective. Needs expert to determine.
If the picture is still bowed, the power supply fuses are open.
Check the power supply on the red connector for + and - 20 volts.
The fuses are on the main board,are on the deflection module in the
middle, tward the front of the TV. They should look like green (or
brown) resistors. An ohmmeter check will show which ones are bad.
They should be 3.5 amps. Replace with 4 ohm GMA fuses with pigtails if
you can't find picofuses. I also had a set that would fry the 1 ohm
resistor on the 20 v supply. This was near the fuses.
I replaced the whole module to fix that.
Today may be your lucky day. Approach this procedure with extreme caution and take your time. Sometimes when you replace that board you have to do a full digital convergence alignment. With tv off, push mute,1,8,3,power. Tv will come on in service mode. Certain buttons can now screw up the set in a major way, do not guess. press 7 to adj. red, 8 for green, or 9 for blue. Then look for the highlighted "x" intersection. Use directional buttons to adj. while careful to watch screen. Vol+ and - or ch+ and - make moves, mute moves cursor. If alignments move up, down, left, and right continue until all intersections are aligned. Turn power off to start over. When done press add/del on remote to save settings. That should fixya.
