Question about Sony Televison & Video
Please tell me which parts to replace
Your convergence ICs are bad. They are about 20 pin chips located on the D board. They are on the largest heatsinks on the board. Check the resistors and fuses underneath or next to the heatsinks with an ohm meter to make sure all are good as they can fail with the ICs. This is a difficult repair but can be handled by a moderately skilled electronics tech. After all bad parts are replaced, run the magic focus to hopefully re-align the colors. If you have to go into service mode to re-align convergence data, the complexity of the repair just went up another notch. On a sony, service mode is tricky and a service manual would be highly recommended. Your tv uses two stk392-150 ICs (ic 1502 and ic 1505)
