I just went into the service menu of my 60V500 to see how many hours the bulb had, in preparation for installing the new bulb (w/cage) I ordered last week.
The TV has been looking a little dingy, hence the new bulb, the TV's first replacement. I've never had one issue with this TV, after Sears had to replace the light engine 6 months into its life. (I had a whole crew out here, learning just HOW to perform the operation!) I got a little concerned back then, six years ago(?), that the TV wouldn't last. I paid all of $3200--a real steal at the time, but Sears was 2 months late in delivering it, the model was so popular. I bought it primarily from the comments here about how advanced it was for its time.
The current bulb has 13,982 hours on it. It still works, albeit a bit dingy like I said. Is that alot?
