I see some G20's in the video, that should be a must purchase vs. the awful G10's, I have a ton of these and never use them.

We would have to see the lamp to know if there is an inexpensive replacement. it's likely going to be different, it's a completely different chassis.
It was fun to watch the sales pitch. INMO, he did a great job of selling the benifits of DLP. It makes you wonder...if Sharp had committed adequate resources to marketing the Z30K, perhaps they would have stayed in the "game". Then again, it's all about cost/benifit. My hunch is that the Z30K just cost too much to make. At the end of the day, they needed to sell it at a high price to make a profit. With the technologies changing so fast (and 3D implementation moving so slow), the bean counters decided to stop chasing a moving target...
Even after a couple of years, it's hard to believe they closed the Z30K out at the Woot price. I still thank our lucky stars every time we fire it up.

It seems that The XV-Z17 uses a ANK15 lamp.

I feel pretty good, I paid less than that and got a warranty.

I mounted the unit last night and the only issue is the fixed image and offset, with very little range for placement flexibility... I ended up having to move my mount and my screen a bit, but it worked. On the other hand, (I know this is not a 30K, but anyone considering the 17K should know) Sharp made a weird choice on the mounting threads on the bottom of the unit- they're really not far apart (about 3.5 inches square) and are not anywhere near the level weight distribution point of the projector. When hanging before tightening the mount, the PJ was tilted back and to one side. Most projectors at least have the mounting screws in a position that somewhat evenly distributes the weight.

Watching some BD last night, the pic was what I remember from the 30K and a lot like my favorite DLP cinema I frequented before moving. Glad to get back to DLP and to find another unit that tames RBE for me. I am hyper sensitive to it and nothing short of the 5X Sharps has worked for me. The BenQs claim 6X effective, but the Sharp must really be 5X true speed.

Yes, that's it. Same as the Z15K.

Zombie- how should I look for lamps to get good ones? Seems there are a bunch out there as "replacements" for $60 or so.

Ha! I remember that guy from the XV-Z30000 video he did but can't find it anywhere now.

Did find the other videos they have about this projector.

unless the lamp model # is posted somewhere, the best bet might be to disassemble the factory lamp housing and see if we can find the model # of the actual lamp. This is how I found the replacement lamps for the 30K.

I'll look into doing that.

The unit I got has 40 hours on it. Can't wait to do some 3D this weekend.

let us know how it looks. Which glasses are you using? The G20's and G30's should work no problem. I thought the 17K also shipped with G10's.

I should know the answer to this...What is the main difference between the Z30K and the 17K?
Is it just the powered lens controls?
Thanks and happy Bunny to all...

The light engine, lens, processing and chassis and I/O are all different between the two models.

both were previously based on business models.

The 30K chassis came from this oddball that was used for museums and conference rooms where the projector rotated to different screen.

I don't think this is entirely accurate. The spec sheet from the 17K reads exactly like the 30K with regards to lumens, Reon processing, irises, dual ICs, etc. Even the lamp rating and lens size are the same- the Fnumbers on both are the same from the initial 2.5, however the 17K range for a 100" screen is from10'4"-11'11" and on the 30K is 10'4"-20'9".

I am only going from memory, but I see no differences in the picture with 2D or 3D, but I am hardly an expert.

You can tell it's a different light engine due to the Z30K haveing a center mounted lens and the Z17K being offset to one side. The lens zoom specs are totally different and the I/O is different. They may be using the same Reon processor as that is a popular one used in many projecotors. Calibrated contrast and light output from pro-reviews are a lot different between the two models with the Z30K having a lot more native contrast over the Z17K.

I almost picked up the 17K a few times before the 30K went on fire sale. The main reason I needed the 30k is the full lens shift. There are only a handful of 3D DLP's that are 'High Power' friendly.

sounds like you got a great price and the G20's are the big sell for the Sharp 3D projectors since they are one of the best 3D glasses out there.

For the prices the Z17K's are going for used, it may be a great 3D-only projector for those who don't need the motorized zoom lens on the Z30K. I would imagine overall image quality to be pretty close between the two when the DI is enabled.

Here's from each respective projector's spec sheet. It shows the different light engines and lenses:



You can see the lens size is quite a bit bigger on the Z30K. The manual irises for both light engines are totally different. The DI for each is a totally different device too as illustrated. The manual iris is inside the lens on the Z30K and just before the lens on the Z17K. The DI device in the Z17K looks like the device used in the PD8150 actually.

Looking at these light engine designs, it almost seems like the Z17K has a fixed offset whereas the Z30K with it's TIR prism is a classic light engine design to be used in a projector with lens shift.

Edit:

Yup, no lens shift at all on the Z17K and it looks like there is a definite lens offset on it too unlike the Z30K.

this is still available, I bet he would take the first 1k offer

http://www.ebay.com/itm/Sharp-XV-Z17...-/251897949635

The new G20 glasses are worth around 40-50 each.

better price than new old stock!

I told you I don't have a technical background concerning this stuff and to prove it, these designs look amazingly similar to me.

One other difference in the two PJs is that the IR emitter is built in on the Z17K where the Z30K is an additional item which allows placement in the front of the room if desired. The 17 bounces off the screen.

The light paths are distinctly different as are the lens designs. As noted in my previous post, the Z17K is built with a fixed offset in mind and because of it it doesn't offer lens shift. This is why it doesn't have a TIR prism and you can see that the light is actually shot below the DMD to mirrors which then goes through a condenser lens then hits the DMD at an off angle and then leaves the lens at the same angle. This is why the Z17K has a fixed offset to the lens. This is a trick to increase on/off contrast. The point to this design is to capture stray light in the barrel of the lens so it doesn't go back and scatter on the DMDs surface. The Z30K doesn't have this. Then you can make out the different physical irises and their positions in the light path and optics.

My only point here is that they are in fact quite different by design. I would equate the differences between them by comparing the Z17K to a Infocus IN8x series projector and the Z30K to a Planar PD81xx series projector. Both perform well, but by design, they are quite a bit different internally. Both have very different light path designs and optics. I think the biggest difference between the two is placement flexibility is much greater on the Z30K as the Z17K doesn't offer any lens shift, has a fixed offset to the lens and offers greatly reduced zoom compared to the Z30K. This alone makes the Z30K more attractive as Zombie points out. The Z30K is one of the only high power friendly 3D projectors out there.

From TI's white paper. They refer to these two different designs as Telecentric Architecture and Non-Telecentric Architecture:

Z17K's design (fundamentally):




Z30K's design (fundamentally):



The Infocus IN8x series projectors have a similar non-telecentric design as the Z17K has and the Planar PD81xx series projectors have a telecentric design similar to the Z30K. The advantages of each are listed. For the full TI white paper you can read it here.

Thanks for that. Very informative stuff regarding the pluses and minuses of each.

thanks for the links. I just looked through the 30K service manual, it's amazing the engineering that goes into creating one of these projectors. So many different components working together to create the images that we take for granted from today's technology.

I can imagine seeing today's projectors 30+ years ago, it would have looked like science fiction. Kind of like Marty McFly showing 1950's folks a video camera.
