When I power TV on the small Blue & Yellow LED lights on the front of the TV that indicate if TV is on or off; keeps changing back and forth from Blue to Yellow every like 5 or 10 seconds. 3.) Start-up problem, etc... A.) Please let me know what to do to get the tv to work. B.) What is causing the Red Picture Blur or ghost type smudge on TV screen and how can I fix it? Your assistance will be very much appreciated. Thank You, Ralph

Blinking of the the LED (yellow and blue) at the front panel indicating that the lamp door cover is not seated properly. This cover will engaged to a micro switch giving the signal to the processor, once it is in open position, the unit will not power up and will experienced that kind of blinking error code. Go back to the lamp door cover and ensure that it is properly seat-in.
3D, 2D, red/green/blue ghost on the picture and letters means that the convergence circuitry gone bad. Symptoms is not connected to the light engine. The faulty parts is the convergence chips(IC). This chips are mounted on the large aluminum heat sink and starts with STKXXXX-XX (X means number). The most common STK chips used on Projection TV's is the STK392-110. You have to replaced them both on the board to resolve the issue(red ghosting). It is necessary also to check the resistance value of the resistors around its circuitry using the multimeter.
