Westinghouse SK32-H240s won't power up?

I had this Westinghouse 32-inch LCD TV (model SK32-H240s) for less than two years. It will not turn on, and the power indicator is purple. I replaced both boards inside, the power inverter and the main processor board (purchased from Discount-Merchant.com), but still having the same problem?????? what else could be wrong... thanks for any help or suggestions
