[Resolved]  Sony Hp29m93 — Showing some colors after swithching off

After switching off my Television, I could see some color lines are coming to center and it narrow down to a point and become white. Since its 6 months OLD TV I wondered. I contacted an authorised technician and he changed the transformer, still the problem persists. His assumption is that, it could be the problem with Picture Tube. I need to change the picture tube and told them to give me a new TV, since it is in Warranty period. If anybody had the same issue, please suggest the solution which u have experienced.<br />
