I bought a Mit 55'' in 2001. It had been working fine untill I moved last month. After moving I experienced that my TV displays incorrectly. The problem is following: 1. When turn it ON, it takes longer to display picture 2. After it is ON, the picture (including the closed caption) is bended and produces mosaic color like a rainbow. This phenomenon stays for around 2-3 minutes then it disappears and comes back to normal display.
Thus could you identify what the cause(s) is (are)?
