When turning on the tv, there is a humming sound and no picture. The TV turns itself off and on 3 times and then turns off and give a 3 blinking light code with the power button. This code indicates the Lamp is bad. The Samsung Tech Rep said the humming sound could be comming from the Color Wheele, Lamp Fan, or Ballast,
Do you know how to change out the color wheele? Lamp Fan?, Ballast?, I already have changed out a Lamp just 6 months ago and did not have this humming sound; but the Lamp does have a cracked lense.
