I have a Kodak V570 with 5 MP's and a Digital Concepts camera with 6.1 MP's and I don't know which is better, so could you also give me your opinion on that?

I have a Polaroid tda-03211c... I have had it for about 2 years now... When I turned my tv on one day it started to shows negative pictures. After a while later when I turned the tv off and tried to turn it on back the tv won't come on... There is now just a red light on and it won't turn to blue don't matter what I do... My repair guy said it what the main unit (video board) that had the problem so I decided to search for the serial number to see if any store was selling a replacement.. I found the exact board at shopjimmy and bought it... When I had successfully installed it I plugged in the tv outlet to the wall only to start smelling a burning smell... The Main unit board that I bought started to burn. To be specific on what burned, here is a picture http://img826.imageshack.us/img826/6998/10082010391.jpg But I tried to reseat the board again and the red light comes on but it won't turn blue...
Can some lead me in the right direction as to what is problem iwth my polaroid tv?
