[Resolved]  Sony Kv - Hp213m93 — Bad Video quality

I have purchased sony KV-HP213M93 on October 28, 2007. After instaling the TV, I noticed that the picture is shaking and I felt so upset. Immediately, I called Reliance Digital Store where I was purchased the TV. They replied me that they will come in 48 hours, but it has been 1 month no body looked into my problem.
