hi there everyone well after an attemp at a 7inch projector ,with a lilliput that gave up on me ,and then a 5 inch ps one screen used in the same projector that was just causing head aches i decied to give up and thats it all over,hahah no not really ,i dont give up that easy ,i been looking thru these posts for a while now ,
and found alot of usful info,which is great ,but here i am again back to square 1,
this time im going for something simple that works!!!! so ive just gone out and bought a 17" viewsonic ve710 lcd screen,which is huge!!!specialy moving on from a 5"!!! now before i get going and go all out just want to ask if any one has done a 17" pj screen with excellent results and what is the easiest way for me to set it up get it all working nice ,ive been looking at the post and theres some awsum amazing projects being built i really have to admire people with this sort of high level of skill and creativity ,but for me im just looking for a basic design that is going to work and be usable any ideas people???????????
i could to the lumen lab box way which looks the most basic to me but maybe some one out there has a bit of experince with 17"lcd and knows a good way to set them up,any way any and all comments are welcome,im from the diyaudio forums and though id make my new plog on here for a change ,so hopefully ill get some help along the way and may also be able to help some one my self cheers..

woops sorry about that double posting !!,just getting use to this system,

ok well hers a big question for all you guys out there,any ideas on whats going on here or advice be greatly apricated at this time,

so ive started to strip the lcd ,now as my camera is about the most budget camera on the planet i cant really post to many pics at this stage sorry guys!!get a new camera soon,but heres the thing i removed the rear cover and the control boards wiring etc and i was about to get ready to remove the back light when i found this problem..ill try explain please bear with me on this one,,,
there are 2 boards connected to the lcd screen one at the top and one running down the side,now these are joined together with a Very short cable,ive included a shot hopefuly that will help yous understand what im on about!!now the question is:

can i extend this cable in sum way so that i can bend the 2 boards out of the way and still get them connected together????????????????????????????????

or am i up the river with out a paddle in which case ill be very upset as ive just forked out for this new lcd!!!!!!

well there you have it if anyone can help me out with this be very helpful,hopefully some one out there has had the same issue along the way and found a way around it....

Hi and welcome to the forums. I am waiting for the 17 inch pro lens which are being made for the 17 inch monitors by lumenlab. The first pro lenses didn't work out so most here have been waiting for 5+ months now for the new pro freshnels. The pro lens prototype which Brain got last month got 2 out of the 3 problems fixed and is now being reworked again. It can be anytime now that the pro lens kit will be available to us again.
Maybe you shouldn't strip your lcd right now, that way it won't be laying around to get broken. The 17 inch lcd's are a little tough to build without the correct freshnels and pro lenses. Some have had luck building one by using the freshnels from diy projectors. They will make a larger box if you use the freshnels from there.
As far as the ribbon goes there should be an extension ribbon available through lumenlab for it. count the number of wires then measure the width and look on the lumenlab product page.
Hope this helps.
Good luck with your pj. Hope to see some awesome pics soon.CS

Check out Matropalis' PLOG:

http://www.lumenlab.com/forums/index.php?showtopic=3527

From this you will notice that it is possible to make a 17"er with the standard LL lens and bigger fresnels as long as the throw distance is not going to be a problem.

Good Luck.

thanks guys for your input,ill count the pins today and see how we go from there,and ill check out matropalis plog also ,i agree with stripping the screen and having it lying around may get damaged,what i was going to do was strip the rest of it and have it set up in a frame already to wire up to the computer to test that its
still works!!! im being extremly careful with this one,but maybe i should just wait till i get the cable or how ever im going to extend the cable be fore i continue ???
ill see how we go today,cheers guys.as for the fresnels ,yes i was a little worried
that i couldnt use the standard lense but i thought that maybe i would just not get the full size of the 17" lcd projected and maybe just have like the size of a 15" projected,would i be on the right lines in thinking this way??????any way ill post more as it happens .

If you use the standard lens, you will get the whole picture, it just will be a bigger projected picture on the wall (the projector will need to be closer to the wall for the 17" screen - not too much closer though). Matropalis said he got a 110" screen at 8' from the wall, I believe (something like that - it's in the PLOG).

I would get the cable just to make sure you got the correct one. Of course if you are going to get it to turn on while you have it mounted you'll need to seperate the board from the lcd. A lot of the members make a "sled" unit to put the lcd and all the circuitry on it so it's easily removed in one piece without dismanteling the pj.
Someone sells a prebuilt sled with keystone ears. maybe someone will post that thread for you. CS

yeah a sled type set up was what i was thinking of,but ive decied to wait and get the right cable first before i get to carryed away ,as i tend to do!!!
just read matropalis plog ,i have to say awum!!!!!! this is pretty much what i was hoping for if not alot better!!!,he has done an awsum job thus far,great inspiration
to myself and im sure many others on here,

well ive just ordered a set of fresnels they are 220/330 focal lenght
and a size of 15.5x13.5 i think these are supose to be able to be used
with lcds up to 17" acording to diyprojector company,so ill keep every one informed as to how they go ,but i think these are the same ones that
matropalis had used in his tests,

now as i live in australia things here are virtualy impossible to get hold of,
so i have to sorce stuff from over seas so please bear with me on these
processes as postage from the states can take up to 2 weeks,

anyway im off to figure out how many pins this cable is that i need to extend,be back soon,....

In addition to the # of pins, you need to measure the width of the FFC cable in metric.

Generally you can divide the width in mm by the # of pins to get the pitch.

ok well it took me ages of checking and rechecking,those pins are tiny!!!had trouble seeing them as i counted!!but i came up with that there is 30 pins,
and the width of the cable is 15mm
so 15 / 30 =0.5

thanks deathray64,ive order a few cables 30 pin x0.5 6inch in lenght and also
a few 30 pin connector thingys from digikey,so hopefully with those parts i can construct a bit of an extention cable????? i guess now i have to sit back and wait for them to arrive,till then im gona read thru the plogs and find out more bout the 17" set ups,......

well hers the first drama of the build and i havnt even started building yet :angry:
the order i placed with diy projector company was refunded due to the fact that they didnt accept pay pal from australia ,only usa :angry:
well im not sure what i can do here im going to ask if i can pay by money order and see how that goes but it takes so long to post the order then wait for the goods to actuly arive! any one heard any word on these pro fresnels at all???
would like to get a set if there all working good now ,

Has any one tryed a 17" pj with standard ll 220 and 330 lenses????????

if they work i might get a set of these and try them but id prefer to do it right
first time round if thats possible??? any way ill carry on with info hunting......

I just took a walk to the workshop... nowhwere near fitting. Fresnel dimensions are 318x250mm, but you've gotta allow a bit for framing. Would still get a few more pixels than a 15", but probably not worth it.

I initially wanted a 17" as well, but I'm making a box (width x height anyway) with dimensions to take a 17 and using a BenQ 15" FP537 for now (absolutely no FFC issues ).

Edit: Oops, it's a BenQ531, BTW, the LumenLabs order arrived within 3 days to me

well i little progress but then a brick wall!!! yes dam extenions heres the lcd in a frame set up but now im stuck cause my extion cable didnt work anyone got any ideas????

Using FFC extensions can be tricky.. they have to be perfectly aligned for them to work.

I was extending my PSone 5" with a FFC extension i bought here from lumenlabs and it took me 6 tries to get the cable seated right.

what sort of problem are you having with your extensions?

well the basic problem is that i have 2 6" cables which are held together by
2 connectors the whole set up is very dodgy indeed but on conecting they did
put alot of lines up and down the lcd ,also the problem with connecting the lcd ffc to the cable as its so very small and flexible the presure of the cable twisting around going from the control board up to the othe board on the side of the lcd is making it very hard to keep it in position ,another thing is that im not sure if the pitch of my extion cable is correct ,it has 30 pins on the control board thats for sure as it is printed on the board in 1 to pin 30,i would put pics up but its probably not worth it as my camera is so crap the pics would be all blurry ,im at abit of a loss for ideas???

Well i could see how it would be very hard to keep all that together.. no wonder it doesnt work..

I suggest you find a single 12" cable so you can remove one of the connectors. And find a way to secure the connectors. I used some electrical tape.

But your probably going to run into problems later if they somehow come apart.

When i had a bad connection with my FFCs it would show a bunch of lines and colors like you said.. so im pretty certain you have a bad connection.

Check/compare the pins on the original cable and the extension under a magnifying glass. Put both ends together and line them up. They may not be exactly the same size but they will probably be close.. as long as the pins line up somewhere and are not touching 2 pins at one you should be ok.

well here i am again no i havnt given up yet but after multipul trys and i do mean multipul!!!of getting my dam screen to work,i decided to take a break from it,tryed again later on in the week but still the same story ,since what im trying to do is firstly get the screen in the frame all working nice and then go from there ,
lucky for me some one has offered to buy the screen from me so i will be investing yet again in another lcd,now as the models that people have and talk about on here are mainly unavailable in australia or if you can find a second hand one yourd be lucky,but ive heard that some one got hold of a hyundai L72s and stripped it succesful with out ANY FFC ISSUES!!!!!HORRAY and this screen is availble to me here in australia and theres one down the road in a local computer shop!!so i think im going in that direction ,i tell yous what if this one has no issues with stripping and cable extentions ill be dam happy !!!!
so heres a question to any one out there who knows,


:
has any one got a stripping guide in pics for the hyundai L72s 17"lcd screen???????????????????????????????????????????


or even a few photos of the screen stripped with control boards attached just so i can see where im headed and if it is going to be a wise investment ,

any one out there got any info on this one be apreciated cheers.

well here i am back again ,good news too!!!
i purchased a hyundai l72s todat and stripped it and attached it to my old sled and fired her up WAMOO it works!!!!!!!!!!!!!!!! about time!!! i guess this is 3rd time lucky for me !!! let me tell you all about the hyundai lcd,

this screen is awsum,its got all the good specs with 8ms which is pretty fast!!!

as for stripping the set up is a tiny bit different from the others i have stripped,but never the less it stripped well,very straight forward and yes thats right no god dam ffc issues!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

this makes life so much easyer ,id love to have post a nice little stripping guide but unfortunatley my camera is just not up to the buisness end of things

ill try put up a few shots and say a bit about it but really any one who haas stripped one of these lcd monitors will be fimilar with the parts and things to be removed ,if anyone has any questions about it feel free to email me and ill try my best to help out,as i know there are a few people on here that are looking at these hyundai screens or there got one on order so here we go bear with me on this walk thru

heres the little beast in question

removed the 2 covers from the back either side of the main support arm,

and removed the 6 screws that hold the arm in place ,also there is a small earth cable under one of these screws remember to push this through the frame a bit later on

next is the frame removal,there are about 16 small slots running right around the frame al you have to do is use a small flat head screw driver and push in to the slots and lever the frame up carefully,you can find each slot by using your finger nail down the slot

Next remove the 2 speaker wire plugs either side of the control board,
and the main control plug.

next there are 6 plastic wedge clips holding the backing frame onto the front screen frame these undo simply with a small flat head screw driver,

frome the screen from rear frame,

next unplug the main lcd board cable connector

then remove the 4 screws on the side of the lcd frame

cut the zip tie holding the 2 control board cables

remove the silver tape covering the back light plugs

remove the back light plugs 4 of them,

then you should be able to remove the whole steel frame that holds the power supply board ,

this is the cable from the lcd main board
