Re: No picture but sound is perfect
Sounds like the video output has a problem. Maybe missing the 200 volts from the High voltage transformer.
The vertical circuit may have an issue.
Either way it's hard to diagnose without looking at it.

I have the same issue, we've had to change our bulb three times in less than two years. now we have 61" expensive paper weight. Our current bulb is less than 6 months old. The TV is only 2 years old and like i said this is our third bulb.
the blue light blinks 4 times. you get sound. then a few minutes the the picture returns... then it goes out, and the cycle goes on.
The problem can be caused by a bad sustain board (Ysus Zsus) , the popping sound is often caused by a capacitor blowing up. The TV must be taken apart and tested before eventually replacing sustain boards.
#1 When I turn on the TV the power button comes on then blinks 6 times then goes off for a few seconds then repeats the cycle. I have sound over my surround system during this time but no picture.
#2 My sound would crackle and pop every once and a while until now it does nothing. I have to watch it with the surround sound on.
