I replaced the lamp back in June and now this fine piece of Chinese engineering is at it again....
I turn the set on, the lights come on, the sound comes on, but no picture. The sound shortly shuts off, the lights blink 5 times and the set shuts off. The set will try to restart by itself two more times with the same results. I guessing it's the color wheel this time, do you agree?

could be the ballast not firing the light, you'd likely hear the color wheel if it were bad. if you pull the bulb out and shine a flashlight in it's opening, you should see the color wheel - if it doesn't look shattered and you can't hear it, you're probably ok... you can try and remove the bulb and turn the tv on and see if it spins up (you'll have to hold down the lamp door switch).
i'd suspect the ballast if the bulb looks ok, and while i was in there, i'd look for bulging caps on the power supply.

I did what you said, the bulb looks OK. I looked through the small opening and it was hard to see, but it looks like the wheel is OK. It doesn't spin constantly, it just turns a little each time I tried to turn on the TV.
To replace the ballast or check the power supply caps I take it I have to pull off the back cover of the TV?

yeah, you'll have to take the back of the tv off, it's very easy though :)
