I think it's just an inherent performance issue. The times I've loaded the scope position settings on mine it's usually off from where it was saved before. I imagine the method of where it tracks the motor step position is not as precise as the actual movement. I also get an axis shift whenever I switch from horizontal to vertical shifting or vice versa. It's an annoyance for sure but all things considered, at least there wasn't a lot of compromise on the optical performance.

Thanks for chiming in. Looking like this something around this size is going to work for me as well. Can you share the price of the Elite via PM, if you don't mind?

What kind of pic are you looking for? I have some pics on my thread you can link to...

I don't have any problem with changing the scope via lens memory... Goes right back to where I had saved it. I have the following 5 lens memory setups saved:
2.35
16:9 (1.78)
1.85
16:9 for my HTPC (slightly different than what comes out on my 16:9 blus)
ESPN (16:9 but with the sports ticker chopped off).

Yeah. It's probably related to the lens motor.

I do prefer the Panasonic lens memory functionality. Pixel perfect every time. Plus the masking is part of the memory, which makes sense.

I was wondering where you guys shop for bulb / lamp replacements. I am wanting to replace my lamp and I am unsure of the various online stores and whether or not the bulb is the actual official JVC bulb. The prices seem to range from $315 up to $400, so it would be awesome if there were some consensus answers on where to get the official OEM lamps from.

I'll be interested to hear the response to this. Odds are though, if your not buying from a dealer, your not getting a JVC lamp.

What I'd really like to know is if you can replace the bulb inside the lamp housing with an OE bulb to save money. That's where the real savings would be, if its possible.

^^Me too. I noticed that the price of 'real OEM' bulbs dropped as the PJ aged....which I guess makes sense. I'm at the 1,600 hour point with my RS46, but brightness, even in 3D mode, doesn't seem to be an issue yet.

There is/was a lot of discussion on the RS1 thread about this topic, so you may want to read that.

If you are using XD fabric, then you need to use the actual gain, which is 0.98, so enter in 1.0. If using UF, then enter in 0.8.

Just bought one for $86.00 Seller says its a real OEM JVC bulb, brand new and sealed in the box. I'll report back after I receive it. I've corresponded with a couple ebay sellers about authenticity, and have been told that they are available for less than retail price. I can share that in a recent visit to China, the ability to buy 'graymarket' electronics, etc. at or near the factory can result in big reductions in price. Maybe that is what is happening here.

As I said, I'll report back once I get the bulb.

A US dealer can't sell an OEM lamp in an OEM housing for $315, without losing money.

Maybe, maybe not.....'graymarket' Ipods, notebooks, etc., can be bought in Shenzhen for a fraction of the USA price. Perhaps this is the case here. An item that is not shipped and distributed through the 'normal' JVC distribution network CAN come from the same factory and be built to the exact same specs. China is not renowned for respecting intellectual property rights, after all.

Is this the case here? Once again, I'll report back after I receive the bulb.

For those who wish to espouse the benefits of buying from the manufacturer only, I'm not engaging. Over $300 for a bulb? Really? Is it made of "unobtanium?"

I'm all for saving money on lamps, but I've read enough reports here from people who bought 3rd party lamps and had significant problems, I don't think it's worth the chance. If you have to replace the 3rd party lamp 4 times as often it's not a bargain. Same if it's not as bright. The current JVC lamps last a long time, even if we assume only 2000 hours, that's only $0.15/hr. Not bad considering a new Blu-ray is over $10/hr, and a trip to the theater is even worse than that.

See what an anamorphoscopic lens can do, see movies the way they were meant to be seen

I was just letting you know that a US dealer can't sell at that price point. There is not much profit in a lamp for a dealer.

I understand.....I used to work for an electronics manufacturer, and the markups on replacement parts were astronomical.

We had a captive audience, and the prices reflected it.

As promised, I'm reporting back after receiving the bulb.

The outer box looked just like the one I paid full price for from an authorized dealer. It was sealed, and as I opened it, the packaging was the same as the OEM bulb. Same for the inner bag, etc. The bulb cage has all of the same markings molded in as the OEM bulb. Stickers, etc. all appear to be the same. Markings, etc. on the bulb itself seem to be nearly identical to the OEM bulb. Same placement , font, etc. from what I can tell.

I installed it, and the PQ and brightness looks as good as the one that I pulled out, which is a "real" JVC bulb installed a couple hundred hours ago.

If I had purchased it from an authorized dealer I would have been convinced I got the 'real deal.' As it is, all looks OK to me so far.

Now it might die quickly or otherwise fail early. I'll post an update as I use it so others can benefit or learn from my experience.

Thank you for posting, I'm at ~2200 hours and looking at lamps, just in case...

Couple of quick questions:

1) You say OEM, do you really mean OE? (OEM refers to Original Equipment Manufacturer, so it could be something you purchased from a company that makes parts for JVC; whereas OE is Original Equipment, and refers to only the original or genuine JVC parts.) Not beating you up, just asking for clarity.

2) Did you get just the bulb, or the whole lamp assembly? (I haven't taken my lamp out, so I have no idea if the bulb is easily separated.)

3) Can you post pics of your original lamp that shipped with your projector and the one you just got?

Hi Dreamliner,

It's in a box that says "JVC" and the lamp assembly says that, too. I would assume that JVC does not make its own bulbs, but this one looks just like the one I paid a lot more for and just took out of the PJ, including the box, packaging, bulb assembly, etc.

Might be a 'fake', but it seems to be a pretty good fake if it is.....As I stated previously, there are situations where at the end of the assembly line in China 'real' merchandise goes out the left door to the USA, and 'graymarket' merchandise goes out the right door. So far, this seems to be the case with this bulb.

Time will tell, I guess.

I'm finding that I'm smarter than I thought, but dumber than I need to be.
