The service manuals from the manufactures are not free of charge. They
are copyright material. Some manufactures will not sell service
manuals to non authorzed service reps.

The common causes of the pre-mature blowing of projector lamps is
improper cooling, or the power supply is out of specs.This should be
properly checked by a service tech who is familiar with the unit and
has the proper service information to take reference with.

It is possible that the lamp you bought may have been defective from
new. We've also seen that before.

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,
