Official JVC X30 / RS45 owner's thread! - Page 140

You should ask for the average lamp life for people with the original bulb vs. those with the redesigned bulb.

I was seeing issues with my original bulb at about 300 hours. I contacted JVC and they sent me a replacement bulb with the new design. I still have the original bulb in the projector as it hasn't seemed to have gotten any worse, but I am only at about 600 hours. I did a pre-order on the projector back at the end of 2011, but didn't install it until almost exactly 1 year ago to the day. We almost exclusively watch movies on it, with the occassional TV show or major event like the Super Bowl, so it may seem low, but actually ends up being a lot of movie time for 1 year. So I don't have a full answer for you, but I did want to mention that there are 2 different bulbs out there to take into consideration.

Good luck. It is a GREAT projector.

Anecdotally, the average life is about 800-1200 hours on the 002 bulb, the 003 bulb = unknown. As I've repeatedly noted, I got 1500 out of my 002 bulb which appears to be more than most, it was dimmer and starting to flicker, but finally exploded into pieces. If you see flickering, be afraid, very afraid, maybe not today, but some day, blah blah...

Keep in mind that most people only report if their bulb dies and not if it keeps going, though we had so many reports on the 002 bulb that I would say 1000 is a pretty good guess on its average. I've only seen a couple users note they got over 1500-2000 hours, out of all the reports, so 1000 is a safe bet.

Thank you everyone for their responses. I am now set on the RS45, now, the next step is to determine the screen. I am looking for 106 or 110" screen. My budget for the screen is minimal, $500. The projector will sit about 15 to 16 feet from the screen with my seating at about 12 to 13 feet from the screen. Any suggestions on screens and gain levels? Thanks!

I would not want to sit farther back than 1.3x screen width, which would be 10.5 feet for a 110" screen. So get the biggest screen you can for that seating distance, 120" would be even better or move the seating closer (just IMHO).

Da-Lite HP screen so you can close the aperture to -15. Even on a brand new lamp, I don't find it too bright at -15 aperture with a 106" HP screen, though my projector is not mounted to get the full gain and it is near farthest throw to maximize contrast. You will be fairly close to my setup except I sit closer to the screen.

I sit about 13' back from a Carada BW 110" screen. Seems to be right for me. 120" wouldn't be bad for me either. I am not sure what bulb I have. I have 850 hours on it and did see significant dimming during the first 400 hours, so JVC sent me a new 003 bulb. My projector is 15' away from the screen. I am at -6 (high) on the aperture and am getting 16.5fl. Nice and bright for 2-D, 3-D a little dim. I rarely watch 3-D, but it is nice to have the option.
After a nice calibration, the picture looks amazing. I had a RS-1 before this. The contrast and sharpness is very much improved. I wish I could have stayed on low bulb as it is dead silent. Very nice projector.

JVC just blew me off when I contacted them about a bulb replacement at 1 year for a bulb with 500 hours that's too dim to watch. They simply quoted their warranty policy and offered a "One time courtesy" price of $340 for a new bulb. Now they don't even reply to my emails.

Obviously the original bulb design was flawed; they had to redesign it and are only willing to warranty a $500 part for 90 days as opposed to a 1 year warranty on the new model bulbs.

Wow, that is a shame (on the warranty of the bulb). My experience was a little different. No response to my first "claim" after about a week of waiting. So I submitted another one, and on that one I received a response within a day, and it was really easy. I had provided them with all of the details in my claim (including my phone number and mailing/shipping address). The just confirmed that they were sending a replacement bulb, when I asked if it was going to cost anything, they said no. Easy peasy...

That was back a couple of months ago on a projector that was just over 1 year old.

Now, I have my front row seats at about 12' (eyes to screen distance) from a 138" 16:9 Seymour XD screen and love it. I was afraid it would seem too big, or that my wife would hate it, but my whole family loves it that size. With 2 rows of seats, you can sit in the back row and still have a nice movie experience.

Now, I went with the Seymour XD screen because I wanted all of my front speakers hidden so that I could fit the larger screen up front. That meant a gain of 1.2 per Seymour's site (I've heard that it is less than that in real-world settings). I do NOT care about 3D at all, so I don't need a light cannon to get an acceptable 3D image. BUT, if I did want 3D or was fine with my speakers being in front (outside of the viewable area of course) of the screen, then I would go with some screen with 1.8 gain or there about. Some people have super high gain screens, but 1.8-2.0 gain mathematically would be great for my completely dark room.

Good luck.

How has your Seymour screen fared with ambient lighting?

First off, let me throw out this disclaimer, all screens look better in a dark (or mostly dark room), so I am by no means saying that it looks as good as when it is fully dark in the room, but it does fine. I say that but I also will mention that I am not a fan of ambient light at all, so I don't really get excited about a picture in a room with ambient light.

I had a Carada brilliant white screen in a previous theater and the Seymour does as well as that does if not a touch better. I don't know how it would do vs. a super high performance (2.0+ gain) screen or a grey high contrast screen though.

Sorry. I wish I was more help.

I know that many screen places will send you material samples. I had my 3 samples from Carada and my sample from Seymour before I made my choice. I wanted a picture as good as what I had before (from a screen perspective) but if I could get acoustically transparent at the same time, then I would be happy. I am totally happy with my Seymour XD.

I m calibrating my x35 atm and I seem to have some trouble with the grayscale calibration. I ve set the mode on USER and color temp on user1 6500k.
I have to lower the GAIN GREEN pretty far down to get a decent overall greyscale. More specific, my settings are now:
GAIN: R 0, G -28, B -51
OFFSET: R 3, G 0, B 10

I always thought/learned that you don t want to change GREEN bias and offset too much (preferable not at all)? If this is true, then I m way off this as you can see!!

I am I doing it wrong or not?
Thxz for input guys

Hi guys,

Did a quick google search but was unable to find the answer to my question.

I have high def cable box connected to my marantz av7005 pre to my rs45. I have 120 h since this this fall. Pretty pathetic. I've been so busy I've barely had much of a chance to appreciate all the improvements to my mits hc5500.

Sitting here watching nba playoffs and nhl playoofs and I notice that the picture seems to stutter..... not sure if that is jitter or jutter. CMD is shut off. I thought that would get rid of it but it still happens. Not often but enough that I notice it. What is causing it? Do I need better hdmi cables? Is it a settings issue on the pre or the pj?

Edit: watching wwe, sit coms, news, cartoons I don't notice a stutter.
