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.

Thanks for the very good advice !

This is a really good point.  A lot of guys who only use the Spyder don't realize this.

Can anyone recommend a good replacement bulb-only source for these projectors? I plan on reusing the housing. Or I should say for the past 3 generations of JVC projectors as they all use the same one.

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 ?

I just checked Professional Lamps - no bare lamps for the JVC's. Not sure why.

I was going to start a " JVC Red Projector Owner's Thread ". But it would be very lonely in there.  ;D In the US, a club of three ! We have one available !
