This is 1 of 2 problems. 1; Convergence(depending on the model of sony, the convergence ic's will have cold solder joints) 2: vertical ic issues. If they are different colored lines & the picture also bends, it's a convergence problem. Else suspect a vertical problem. In the case of vertical issues, most of the time it's a defective capacitor (or cold solder joints.)..Such is Sony. if it's the 3-crt kind of big screen, it's possible for one of the tubes to be going bad. I would have to actually SEE the problem before I could make a more accurate guess.
