Panasonic (PT56WX33G) Blinking red light

Please Help !! I have a Panasonic rear projection TV (pt56wx33g) . The power on light blinks 3 times in sequence. There is no picture or sound. The convergence IC's were replaced ,still no picture or sound .I called a tech and he said that one of the resistors have blown. How do I find this resistor if he is correct? Does anyone have a online service manual for this model. All thoughts will be appreciated.
