I'm just starting the learning process on how to install and set up my XG-852. If you've got one, you know this is a complex beast to configure. Especially since the NEC manuals really suck.
I've been writing computer manuals for 10 years, so I figure I ought to document the process while I'm learning. That way future XG newbs will have a huge head-start, and it will greatly reduce the question load on existing XG owners. So it's in your best interest to help me out. :)
If there are any XG owners in COLORADO, PLEASE
contact me. Your experience could be incredibly valuable in this process. If I could come to your place to have you show me, or better yet you come here and help me set up mine, I'd try to make it worth your while within my already-strained-to-breaking budget.
I've been reading through some of the previous XG setup threads, such as Mikecazzx's thread
, and more advanced experts-only posts like Guy Kuo's Black-Level Calibration
, and KennyG's G2 calibration
(danger danger will robinson!), so I've got an idea what I'm in for. (And I'm terrified!! :)) Between those and trying to extrapolate from Tinman's PG setup guide, I think my starting point should be:
1. Hang projector in desired location. Ensure it's dead level and perfectly perpendicular to the screen. (I haven't mounted my screen yet so I'll put the screen up once the projector shows me the right location.) I believe the recommended way to get the PJ square to the screen is to measure from the L screen corner or other fixed point to the L front & back feet, from R screen corner to R front & back feet, and make sure both front distances & both back distances are equal.
2. Set the Scheimpflug adjustments (the tabs on each lens) for my screen size and set the ceiling/floor settings if necessary.
3. Power up the PJ. Reset ALL settings to factory defaults. Is this as simple as hitting CTL-NORMAL to reset ALL settings at once, or do I need to go through all 500 zillion settings in all the menus? If there's no way to reset EVERYthing at once, is there a specific set that is critical to zero out? Which ones go to non-zero values?
4. Clear out all memory blocks.
5. Center the raster on the tubes, then center the image in the raster. Leave at least 1/4" between raster and edge of tube. (I assume that means the corners of the raster must be at least 1/4" from the edge?) I think the process for this is: contrast 0, brightness 100. Center the STATIC controls for all 3 tubes. (Or did they already get centered in step 3?) Look into the tubes and center the raster using the RASTER CENTER adjustment. (Not centering magnets like on the PG?) Then center the image -- how? I don't see this anywhere. I think Guy Kuo recommends using a ruler to make sure the raster/image are EXACTLY centered. Setting the blanking fits in here somewhere, but I'm not sure how.
6. Center the test pattern in the image using PHASE. (What's the deal with the two different PHASE settings? I think CURSOR PHASE centers the test patterns, but what does the other one do?) Jrobbo had a clear explanation for setting PHASE in this post
, but I don't see how this relates to centering the test patterns.
8. Set up the green -- what next, in addition to getting raster/image/crosshair centered? What if the PJ is level but the crosshair is not?
9. Move the lenses to align the red/blue vertical lines to the green. My understanding is that aligning them exactly with physical adjustments, rather than using the default screen size settings and adjusting with the electronics, will result in a better and more stable configuration -- correct? Then use the remote to move the R and B horizontal lines vertically to match the G.
10. Converge R to G and B to G. I think the preferred way to do this on the 852 is to use the MCAT feature. Help? Does the MCAT take care of all the ALIGNMENT issues -- tilt, skew, bow, pincushion, etc? If not, this CinemaSource tutorial
has a very good explanation of how to do the alignment.
11. Physically move projector to move the crosshair to the center of your screen.
12. If you're still game, launch into Guy's Holy Focus process.
Which steps are missing or out of order? What do I do with the astig? Do I repeat steps 5-10 for each new resolution?
What settings need to be left alone, or changed with extreme caution? (E.g. the G2/white/black levels) What things do you need to avoid doing (like getting the raster too close to the edge) or you can damage the unit?
Is the service manual available online? I've got the installation, setup, operation, and supplements, but not the service manual.
