As a precaution I would backup the profiles the RS540 already has before you run the auto-cal process. One of the issues with the Auto-Cal feature is that the compatible meters list is small and the more common meters people use are often not particularly accurate. I think someone did a study based on several of the Sypder meters and only a few of them he tested out of the bunch he had were accurate enough to actually help the out of the box performance through Auto-Cal and by using an inaccurate Spyder meter actually made the image worse. So tread lightly and make sure the image actually looks better after you've run the Auto-Cal software and if it doesn't load the saved out of the box profiles back on to the RS540.
We do have a vendor that will sell just the bulb, but I don't believe they sell to consumers - it is considerably less expensive to buy without the housing.
I would be interested on this option as well, as I am technician and would be able to replace it in the housing. Is it the original JVC bulb though ?
yeah, it was.........above my pay grade, though....LOL Thanks for giving me the name of the guy who did the demo, yes, it was Jason.....Did an awesome job.....
