This sounds like you may have bad picture tubes. Most likely the green and red tubes. You would have to have them replaced and realigned. I would call a Sony ASC and get an estimate to verify this. An onsite service call could verify if this is what's causing your problem.

At first the picture is ok, and then distorted with horizontal lines i thinks. If the horzontal lines are parellel acros the screen, with an inch apart across the whole screen, your tv needs screen adjustments. Screen voltage may be high. look into the crt base also. Change it first. These also not resolve the problem, LOT may be faulty, with respect to screen focus pack. May need replacement. Try first setting screen voltage to a lower settings and observe.
Typically this is a convergence problem and can be repair relatively easy. Refer to this video to determine if you truly have a convergence problem. Also make sure you use your TV's original remote to make this adjustment.
replace the focus block or try to adjust the screen control on the focus block for red only. this will affect the white balance of the set so adjust it carefully. the focus block is located on the front inside the set. remove the speaker cover then the 4 screws on the front plate. the focus block is 3" x 2" black box with 6 adjustment posts three for focus and three for screen. adjust only the affected screen (R).
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.

I had the same problem with my sony KP-57ws500 rear projection tv. To solve this problem all you need is a flat and phillips screwdriver. Right below your speakers on the right and left side are tabs. Pull out the tabs and remove the screw on eachside. Once that is done remove the speaker cover and you will see a fiber board cover in the middle of the tv, there will most likley be twist ties holding some wires, to make it easier to work remove the ties. Now remove the screws on the fiber board and pull it off. You should see 3 adjustments on the top for focus, do not touch those. Below the focus adjustments on the
