Pm sent. Thanks for the help minnie! |

Forgot to mention.....
I don't think you can measure the voltage going to the lamp (excess of 10,000 volts?) but with the lamp pulled out, I know I don't see any spark "arc" at the lamp terminals...nor do I see anything on the ballast "glow" as Ive heard you are suppose to see. Does any of this make sense? Am I suppose to see an "spark arc" at the lamp connector?? If not...perhaps I have a bad ballast? Wish I knew a way to confirm if my ballast is bad.
Thanks for the help minnie. |

No, but I heard that the color wheel has to spin before the lamp will light and the color wheel won't spin nor will the fans run. And The lamp light is in pristine condition. Nice and shiny with no char spots or burn marks and the filament is intact. I don't hear but one "click" from the ballast and its usually a sec or 2 AFTER the TV powers down. Any ideas??? |

Also, I just tested the ballast.
Coming from the power board (the blue and brown wire) to the ballast. I obtained a reading of 216VDC on initial power on, and dropped to a "steady" 180VDC. I don't know what the standard DC voltage is for the ballast to receive but I "think" this is enough? The power only stayed on for 2-3 seconds before it shutdown. Still, no lamp...no fans, no color wheel life. Oh, and the ballast only made one "click" which was after what i believe was the tv shutting itself down. |

Take the back off and see if the capacitors on the ballast are puffed up. The ballast is the small board the lights the lamp. |

The capacitors don't appear to be swollen or leaking anything. I even looked at the itty-bitty ones. It was very dusty, but I blew it off pretty good for the pic. Here's a pic of the front and back.>>>>
Since I got the ballast torn out...is there any volt ohm meter test I can preform on it??? |
