50-inch Samsung model HLN507W had it's bulb replaced by a service tech from
the local shop. Replacement lasted a 1 day.

Anyone have experience with this model? What should I suspect is causing
bulbs to burn out? A common problem?

Are there troubleshooting or service docs available on-line?

Thanks,
Sparky

bad ballast ?
We just replaced a Lamp&ballast today at work because of a bad ballast
over voltaging and burning out the lamp. Normally you may detect extra
brightness abilities before it goes out. Now the lamp we replaced today
was used just for over head lighting how ever, these lamps are the same
technology used in DLP rear projection.
