I didn't see any of the glass type material you mention, but I did see the spheres inside the arc tube. It was explained by ACE that these are vaporized upon the first firing of the bulb forming the halide gasses inside the arc. I can confirm after I fired the bulb they were gone. 😉
Mounting the LCD
>Once you strip the LCD you'll notice that the backlight snaps into place with a white plastic "square ring" into the frame. You should be able to pop this ring out and remove the backlight while leaving the LCD in this metal enclosure. My *guess* is that after the backlight is removed, you could replace this "plastic ring" and have a perfectly good protective mount.
That's what I did with my Proview 566s: The LCD and backlight assembly was held by a plastic injection molded part that covers the entire back surface. I took it all apart with a Philips 00 screwdriver. The plastic part can be lifted off the LCD, while the LCD remains loose in the metal frame. Then I cut the center portion of the plastic out, so it would not block the light. I put the plastic back in the frame around the LCD. Eight of the tiny screws hold the plastic into the metal frame. The metal frame has nice mounting tabs on both sides, so it is easy to fasten that to an aluminum angle frame. I surrounded that with a wooden frame so I could hold the flopped driver boards in stable positions without any strain on their flex cables.

Same boat too
Hi guys, Im in with this project. I found here in Italy the proview at a very decent price (185 EU), so Im ordering it soon.
I'd like to know what's your actually planned setup for the optics. I think that the best choise is to go for the DIYCOMP. long throw kit, cause i think that 15.4 is too much for the standard 80mm triplet. Ill then cut the frenel lenses to match the panel size. I'm also ready to buy the 400w HQI from exclusiv, with 5200K temp for colour, and they give you also a UV/IR filter, do u think that will be enough for potection? Will my fresnel condenser melt?
I will share any experience I'll once I receive the items, but before I go for 'em I'd like some opinions of this setup.
Thank you & GL.

Wow... an Italian guy finally. I was beginning to think that none was.
I went for the OHP method and ... wow, never thought it could be so good! I used a Benq 557 v2 , as many others.
But I'm very curious about a total DIY approach... so let me know how yours turns out. Maybe one day ...
P.s. My OHP has a 80 mm triplet and works very well... why use a long throw?

Hi abner, I was going for the OHP method but after I changed my mind cause i'd like to integrate a motherboard with 5.1 audio output and a whole operating system along with the projector. It'll be an awesome machine I think. Here in Italy I didn't have luck with the materials. No one selling optics or complete light kits as I know 
If u have any online supplier let me know before I place the orders.
I live in Rome, maybe we could share information and experiences on this project. I'd like, if my costruction is successful, begin to sell this prototypes... could be an idea...
I think that the long throw is the best with the proview panel cause that optics are brighter, u can place the pj behind the viewer, and cause of the diagonal of the panel (15.4) is a better choice IMO (often 80mm is good up to 15" lcds).
Let me know.

I stayed with the OHP method because I already have a dvd/divx standalone player and a 5.1 system.

Well, not in Italy, but in Germany and France there are (Italy sucks as always... a step behind everyone).
I'm going to use www.gadaffy.ch.vu or www.izzotek.com . Got these links from www.allinbox.com and www.diy-community.de
Too bad I don't know French or German... 😕

Proview
Hi JL2, glad to see some Italian is reading this forum beside me!
Just out of curiosity: where do you have found the Proview for such a measly price? I've just found a 3m OHP, and I'm thinking about building something for my HT room/home office, and the Proview will fit the bill nicely.
Thanks.

Hi all,
It is good to see some more people giving the ProView a shot. I'm glad it appears to be available on that side of the pond also. I believe it is currently the best true HD capable widescreen LCD available to us DIYers. I only wish it had a DVI input 🙁
As for a update to my project...
I was involved in a car accident last Friday and managed to break both of my feet
. Fortunatly, no one else was hurt, and I am OK otherwise. I am still going forward with my project, and plan on starting to build my box as soon as my optics arrive.
It has been almost a full month and I have yet to receive my fresnels and triplet from DIYProjectorCompany. Alan stated that he received the backordered fresnels last Wendsday and was shipping orders out. Allthough, as of today (1 week later), my order still has not shipped. His website states he will not be shipping orders this week at all. This pretty much ****es me off that he did not ship out all of his backorders before he went on holiday or what ever he is doing this week. Not very good buisness practice in my opinion. Unless he has a very good excuse for this, I will no longer be doing, or recommending doing buisness with DIYPC.
On a lighter note, I should now be able to devote quite a bit of time on this project as I'll be off of work for a while. Granted this is if I get my optics before my feet heal up 😀
Anyone else moving forward with their projects?
Jl2,
I'm not sure what type of UV and IR filter you would be getting with that bulb, or if it is built in. You would almost certainly want a piece of glass inbetween your bulb and fresnels to create a thermal barrior to keep the hot air off your optics. A good peice of IR reflecting glass would be ideal.

Hi alby, I'm glad too to see other italians on this forum and in these projects.
I found the proview in different shops, but I'll buy here: Primestore (+2eu more than lowest price found) cause I already bought from them and they're very serious and fast.
About your project be careful: this lcd is a 15.4" and aspect ratio is 16:10. I dont think it'll fit in your OHP. Again, it is better to build a custom enclosure for this type of panels, also because of the rapid developments of lcd panels (I have heard that several factories are developing HDTV in the 15.4" format), you'd like in a near future to upgrade your panel, and you'll just have to substitute the lcd from your box, and in this type of configuration it will even fit a 17" if you want. That's why I'll buy the long throw optics, cause they can work nicely also with such diagonals.
If you like to go for it along with me we can share very useful info. Let me know. Also abner could be interested. Italy seems very far from building a good community of DIY PJ, and for selling parts in general: by now italians are too busy in being fooled by the ebay's big screen scam!!!

Eh eh eh ...
Ah, what a lovely and full of idiots place to live 😀
Hi inkog, Im sorry for the accident and hope you'll be ok ASAP.
I was going to buy anyway the IR & UV glass, safety of pj comes first!.
I am worried too about alan's shipments cause I already heard that he's very slow deliverying materials. I am going to order in these days from him, after his officies open again.
I very impressed about specifics of the exclusiv light kit, you can find here: LINK.
I will order it tomorrow, but I have some concernes:
about reflector: would a sferical reflector be ok for a 16:10 panel? I mean would the light be uniformaly spread also at corners? I think that an elliptical one would do better.
about fresnel: did you order the 16:9 fresnel from alan already cutted to fit 17" widescreen? I think that they are ok even if larger than the proview panel, the important IMO is to place the lcd in the center.
And are they already splitted, how to split them? the rear fresnel must be adherent to the IR glass facing the light, right?
about the proview: did u find a way to set the resolution of the lcd to 1280x768 with the black bars above and under instead of the pixels streach?
Thanks in advance, I'll keep you up to date as soon as I have info.

Jl2,
Q: "about reflector: would a sferical reflector be ok for a 16:10 panel? I mean would the light be uniformaly spread also at corners? I think that an elliptical one would do better."
A: Under ideal conditons, a perfect spherical reflector would produce a uniform cone of light when used properly with a point light source. As you know, we are not able to use a true point light source, and perfect reflectors matched to our bulbs are hard to come by, so us DIYers are forced to make due as best we can. With that, I think a spherical reflector setup is still our best bet. A good spherical reflector should produce a bright, evenly lit, circle of light on our LCD much like Fig1 on the attached drawing below.
I'm not totaly clear on your eliptical reflector question, so here are two answers: (1) If you're thinking an eliptical reflector would "smash or narrow" the circle into an elipse shaped pattern of light, allowing you to reduce the amount of wasted light. This is not true, and would greatly increase the unevenness of the distribution of the light. (2) Now if your thinking of using a true eliptical reflector as it was intended, much like how most flashlights work (or "torches" on your side of the pond 😉 ) ... the MH bulbs we use would produce a dark spot in the middle of the light cone due to the arc chamber being closed off to light on the ends. Do a little research here if I'm not making since. Thats how I learned.
Q: "about fresnel: did you order the 16:9 fresnel from alan already cutted to fit 17" widescreen? I think that they are ok even if larger than the proview panel, the important IMO is to place the lcd in the center.
And are they already splitted, how to split them? the rear fresnel must be adherent to the IR glass facing the light, right?"
A: I went with the uncut 15.5x15.5" fresnels because I wanted to make certain that they were large enough to work in any custom configuration I decided to use.
They come "split", no need to seperate them.
I would not place the fresnels in direct contact with your IR glass. The IR glass may become quite hot. I would use another piece of class, or your UV filter to support your fresnels.
Q: "about the proview: did u find a way to set the resolution of the lcd to 1280x768 with the black bars above and under instead of the pixels streach?"
A: Yes there is a OSD option to keep aspect ratio of smaller than native resolutions without stretching. Supports these resolutions:
640x480
720x400
800x600
1024x768
1280x768
1280x800
Hope this helps,

Newbie here. I have this proview widescreen panel and stumbled across these forums while searching for info about it. Mine has one dead (unlit) pixel near the top right. Other than that it's a fine panel for HDTV. I'm watching how this progresses along as this is something I'd try to do with my panel in the future. So I hope everyone using this lcd has astounding success!😀 It's going to make things much easier for me should I try this later on.
does anyone know if there's a usable component to VGA adapter? I'm planning on building a projector using one of the screens this summer (unless something better comes out, of course). I'd like to be able to hook up my xbox to it
Dyne,
I think that you can build a DIY component to VGA adapter as the signal is essentially similar. I seems like I have seen this issue come up before a long time ago and I would search AVS forum as their might be something on it.

that type of cable will not work unless the monitor supports SoG (Sync-on-Green)...
If it doesnt, look into a V-digi or whatever box that can actually convert a component signal to VGA...

Thx Inkog for the answers, I've found a friend in Italy that will construct a pj too, but with the benq panel. I can share the shipping fee with him so I'll order next week all the materials. I'll let you know my progress upon items arrival.
Meanwhile, thanks to all for the support. 🙂

Inkog,
I also have the DIYCo's 135mm triplet and 15.5x15.5 330mm fresnels, are you able to focus your 15.4" Screen from corner to corner? I am using a mock up screen right now, as my wuxga kit hasnt arrived yet, but I am having problems getting the corners and the c enter to be in perfect focus.
It almost looks like the triplet would work perfect on a 15", the blurring occurs right outside of the 15" mark I think.
Let me know...thanks

hi minoten, are you diybuildergroup menber?
could you try to ask from where you get your triplet the field angle this lens is capable of? I have no answers from diylabs/diybuildergroup. Please try it yourself and share it.
The max field angle is defined by construcction, i dont know the way they meassure it but we can see if it works with 15" or not.
I believe why is it taking so long for me to find this spec. (maybe bad news are being shut up).
