Query: Flawed item and horrible return policy for return of defective device

I bought this item to use with a digital converter box, it worked well for the first day or two.Since I don't use this TV quite a bit I was not happy to find that the power supply had shorted out or at the very least was not working and the reception was horrible.I went online to Amazon to return it and found that the window for returning it had closed. (slam)I would think that since it is defective that the window for return would be 30-90 days as it is for most electronic devices that are defective.Needless to say my days with Amazon are over.Guess they don't need my business and I know I don't need their attitude.
