What's wrong with my JVC M#AV-64WP74 projection TV?

My TV was working fine and I was trying to make adjustments to the picture. I selected the convergence and as it began going through the convergence test the screen went blank and the speakers began poping. Then the blue power indicator light on the front of the TV began to blink 2 seconds on 2 seconds off continously. I tried to unplug it and when I turned it back on it began to do the same thing. It never has a picture, the speakers pop, and the light begins flashing.
