If you take the front cover off the tv, you will see 6 little nobe, the top 3 are focus, bottom 3 are brightness, should be RED-BLUE-GREEN in order from left to right, find the one that is blue, turn it down a quarter turn, should fix the problem

I tried the solution that was posted for this problem and it worked!
Just remove the Low front panel by removing the two bottom screws that are covered by two screw covers, then remove the second panel (black) by removing the 4 screws then you'll notice a module with 6 adjustment knobs, get a small screw driver, and with the t.v. on, being carefull , and with somebody accross the room looking at the screen begin with the lower left knob and turn left very slowly and ask the person across the room to let you know if the screen is better or not, after this I had to adjust the green as well so, I adjusted the next knob over to the left. Do this adjustment carefully and try to remenber the original position of the knobs in case you have to go back.f
sounds like bad CRT, some of these sonys have had defective CRT issues, usually all will come and go sooner or later (all 3 bad), you can pull the speaker grill off(either 2 1/4" screws on bottom or 6 1/4" on back sides) and pull off the Crt box cover (2'X3' piece) and lightly tap the CRT's with tv on, if they flare or get colored streaks in pix they are bad, CALL SONY 800 # and complain, also could adjust G2 (Screen control for color) for short patch. Will need new crts.
Guys I did this myself real easy. Just don't turn the corresponding screw too far. Only need to adjust it until the lines go away. Do it on a darker screen so the lines are more visible. I did the red 2 years ago and the green 6months before that. The blue lines are coming on my screen now and I've fixed it in 10 minutes. The TV is amazing.
they gona get worse to dead circuit, a small capacitor (problably in the neck board) is bothering you, get a tech now that he can see the problem, gonna be cheaper now....good luck
ps some times the picture say to the tech was going on
