Maybe it will help someone.
A nice Christmas Eve I wish everyone.

Very nice video bony!
Love the music playing in the background,don't know what they are saying, but they sure seem happy singing it. smile.gif
Are you gonna post a focus adjustment video, so we can see how to fix both the all screen focus uniformity, and the Focus Wheel play.

It would be a very nice New Years Present! to have perfect focus and more play in focus wheel so they can get bigger screen sizes! smile.gif

can someone list which 3D glasses will work with this PA70G projector? i have Samsung SSG-P2100 glasses and some LG AG-S250 glasses. will either work? if not, do the Sony 3D playstation glasses work?

Translation problem with your last post.

Question: Can you fix the uniform sharpness by JUST adjusting the 3 screws? Yes or No

Did you add washers or any else to the screws to get the better focus in corners? If so, what?

Do you recommend if we have unfocused units to open up the 70G and adjust the screws?

As to the focus wheel. You have not addressed that problem, yet?

Is there anyone on the web that lists how to adjust the focus wheel to give it more play?

I wonder if we have to loosed something , move the lens, then retighten, and then it would give us more play (in either allowing bigger screen sizes. If we
moved the focus wheel the wrong direction it would make focus closer to screen. Hope that makes sense. I am just thinking of possible solution.

I'm not suggesting you try to work on the focus wheel, if it ain't broke, don't fix it. Maybe someone who enjoys working with this stuff could do it.

I have all 3 screws completely and firmly pulling on the newly enabled Insert

Thanks for the vid bony! However, the key part (the last half of the video) was kinda unclear. Perhaps you can get somebody to hold the camera for you and point to where you are working? It is impossible to tell what you were doing. What is the "newly enabled insert" you speak of? Did you insert something like a washer or a shim behind the screws? Which screw? All of them or just one corner? Or perhaps all you needed to do was tighten them all up?

I called LG last week and they are sending me a return shipping label. Since it does NOT look like you need to cut any serial label/stickers to crack open the case (IE this does NOT look like it will void any warranty), I wonder if I should try this fix before I send mine back to LG for repairs?

Got my LG PA 70G from FRY delivered in India. The first impression is I liked this. I have panny in office but this is better.
I need a wider screen now. I am getting 130 inch diagonal image from 9 feet.
I will try and post some more details when my screen is ready.

I have never seen an unit with horizontal position.

Thanks, tataniko.
If nobody says otherwise I assume that despite it looking counterintuitive, vertical is how it's supposed to work.
LG clearly failed on the focus-system though.

I think the LG PA70G is an amazing LED 720p PJ. It just came out 5-6 months ago, and in first projection of unit, it had "focus issues", no doubt about it. But if you can get a "focused" unit, that seems to be happening more and more with newer manufacture dates. It is pretty cool device.
I like that the built in media player plays all my movies/mp3s/docs (98 percent of them), so all I need is memory stick.
2 year warranty, 30,000 hours on LED, kick ass stereo speakers that rival my hdtv speakers. Don't know how they did it. I mean it's not subwoofer home theater sound, but , in such a small package, the sound is kick ass. My current unit is focused as good as my bulb PJ and my bulb PJ is 1080p. I wasn't expecting that. And it's easier on my eyes in the room I'm in. My bulb PJ is great for 1080p content and for bigger screens and for giving a more POP image. But on a day to day use, my eyes feel better using the 70g, and I can turn it off and on, anytime, like my hdtv.
If you got a first production unfocused unit, take it back, or exchange it, or open up PJ and see if you can adjust the screws. Other than that, no problems that I can see. I'm glad No pro reviewer gave review on it yet, I sure hope they get a focused unit, or the reviews could be pretty bad. smile.gif

Some third party controller can pass away this EDID limitation, and it can switch to 3D 720p, but it is depending which projector, firmware and which controller. At the moment, we have no information about anybody could achieve 3D 720p with a 3rd party controller on LG.
So, we have only one possibility to achieve 3D 720p with a 3rd party controller: HDMI - VGA converter. But LG PA70G accept: 720p@120 through VGA with CRT timings only.
So if your HDMI-VGA converter will convert HDMI signal with LCD timings, that will be puzzled. So, there is no warranty at the moment, which HDMI-VGA converter(chip) will work well.

There is no such thing as crt timing or lcd timing.
He may be confused becaused CRU Utility allows users to select from those two choices, the program's wtiter made it that way so the it would be easier for noobs to select.


•Generalized Timing Formula (GTF) is a method of generating industry standard timings used by a wide variety of display products
•Display Monitor Timings (DMT) are a list of VESA standard pre-defined timings which are commonly used within the Computer industry.
•Coordinated Video Timings (CVT) were released on March 2003 as the newest VESA standard for generating display timings
•Coordinated Video Timings-Reduced Blanking (CVT-RB) is geared specifically for non-CRT display devices. CVT-RB offers reduced horizontal and vertical blanking periods and allows a lower pixel clock rate and higher frame rates.
•EDID Timing is the preferred timing standard defined by the display's Extended Display Identification Data (EDID) value. EDID is a standard data structure that defines the display device's configuration data and mode support which allows optimum use of the display

This is the one I use with my PLED-W500 and VP3D1 http://www.amazon.com/ViewHD-Digital-Stereo-Analog-Converter/dp/B0080D3Z24/ref=sr_1_12?ie=UTF8&qid=1356379074&sr=8-12&keywords=hdmi+to+vga+converter

Like tataniko said, no one has comfirmed that any of the 3D converters can be made to work with the PA70G. It's very probable that it can be done, since it has been achieved with the Qumi, K330,ML-500 and PLED-W500.

For those with ps3 or who don't want to go through PC to get 3D, what do you think of this?
http://www.amazon.com/Arrival-KDLINKS-HD700-Extreme-Built-In/dp/B008CBQSKU/ref=pd_rhf_dp_p_t_2

I do not own it, but just wondering if something like this would work for us. It will play 3D ios, etc, decode them, and the reviews are good from the decoding standpoint. As a web surfer, or apps device, some people don't think it's up to speed. Would this be better device then the optoma and viewsonic 3 d devices. What do you guys think?

Only DLP link glasses will work with the PA70G, it does not have an IR/RF/BT emitter for 3D glasses.

These glasses are said to work with the PA70G... http://www.amazon.com/SainSonic-SSZ-200DLW-Rechargeable-DLP-Link-Projector-White/dp/B007MYZE26/ref=pd_sim_e_3

Did anyone compare this unit to the Acer K330?

Which one would be better and why?
Things i'm mainly interested in is picture quality, lumens output, contrast and blacks (so maiknly for Movies.

I checked a lot the last days but i find no comparison anywhere.

I'm considering going for either the LG PA70G or the Acer K330.

Thanks for any feedback.

Nice video for taking the top cover off of the LG PA70G.
It's good news to hear that the newer PA70G models are coming from the factory with no focus issues.
Either I wait to see what the projector companies are coming out next year with 1080P affordable models or in a few months people will be getting more constant no focuse issues units from LG's factories.
Merry Christmas to everyone.
Do they have take out Slavic food there that can be delivered to the USA ? Bryndzové pirohy ? cheese filled dumplings ?
Just joking, the food would be very cold by the time it's get here.
Merry Christmas Bony

Pawel Dubiel ? I wonder if it's possible to retro fix a old zoom lens from a older bulb projector with the LGPA70G ?

If the screw hold line up would it work ?

Is there any difference in the lens physics between the old bulb based projector lenses and the LED ?

I got a old Infocus X2 projector with a zoom lens.

I know some would say that instead of making the old Infocus projector inoperable, why not buy a attractable lens to place in front of the LGPA70 Lens ?

Maybe ? because I am cheap ? poor man's approach ?

I have the Benq W7000 right now and compared to the ML500 I had last year, the W7000 is 4x as bright, its not even close. I got 360 lumens in best mode on the Optoma ML500 and I got 1350 lumens in Eco mode in the W7000. The fan noise did not bother me on the ML500 but the brightness was just not good enough. On my 100in screen I got around 13ftL with the ML500, which just too dim for daytime viewing. I don't really like watching sports or playing ps3 in the pitch black. With the Benq, I can get up to 50ftL with excellent color to watch anything with the lights on. Even when I'm watching my JVC at night, I keep the brightness between 16-18ftL, 13ftL is just not acceptable on the ML500. I thought the perceive brightness would be more, since people state LED projectors are brighter than bulbs, but that's not really the case to me. I will have to see a review on the LG to see how bright it is.

Most importantly, picture quality is not in the same league if you are viewing HD material. On a scale of 1 to 10, I rate my RS55 an 10, my W7000 an 8.5, and my old ML500 a 3. I'm still keeping an eye out on the lumens on the LG pa70g. If I can get 550 with good color on the LG with a HP screen, I should be able to get 30ftL with a 96in screen.luojie

If you can unscrew the 3 screws remove the rubber lens ring screwed the top screw and tighten the lower right and left lens controlling the swing. Do not tighten too much so as not to deform the lens plastic sleeve in the lens body I loose some two lower. and I can say that the picture is better.
The disadvantage of this solution is the need to move when adjusting the lens and instantly set no longer touch for some time smile.gif Work on further approximation of the lens so that the sharpness already caught in the lower range of adjustment.
In older models of LG were mirrors behind which guided typing a screws H and V
maternity beam of light falling on the DMD. H via screw it passed a red light strip to the edge of the image against a black background and controlled uniformity on white background PA70G are prisms and do not know if they can change something. Turning 90 degrees to the lens sharpness is functioning properly but appear red reflection off the image n the bottom and top.
Everything is manageable

Image without the rubber ring



red light reflection off the image with the lens rotated by 90 degrees

You have pretty amazing equipment, not just the stuff you talked about in this post, but I see you have a panasonic vt50 which you just got a couple of days ago, 2,000-3,000 dollar LED hdtv. With the PA70G I think you might have to look at it like a netbook/laptop compared to quad high end PC. smile.gif
If you like watching with lights on in room, yeah, the LG70G is not gonna cut it. The advantage of 70g comes in portable, built in media center, built in decent built in sound, and good lumens in comparison to all the other 720p LED's and cheapest price when on sale. For you, maybe it's something you would use in the bathroom, at night, with the light off in the bathroom. Because you got super high end PJ's and hdtv's and sound systems. Why would you be even interested in 720p led 399 dollars PJ.
The advantage for me , is turn on and off at any time like hdtv, and small form factor, and good picture in dark, and if unit is in focus, good 720p image.

Sorry mate, but you don't know nothing about Kalman Tihany (CRT), or Janos Neumann (Computer), or their culture background, even a word.

You have many anger in your heart, and at the moment you very like to demolish or lead others. This is not a way. So, sit back to your chair, calm down your mind, and learn, learn and learn , find the first technology university in the world, travel there, bow down, and then you will understand why is different spoken language (not only English) and the standardized one. Then we can speak same langue, and friendship. Thanks

So the picture on my photo is DVB-T set-top box connected via HDMI 1080i resolution on the menu because I have more lines in the list than the 720p.

Diagonal Screen is 270cm, and diagonal image from PA70G is 255cm.
Not only obscures obscures the window screen and it is enough to watch in the dark, watch a day for maximum energy savings and never turn on the minimum saving, in the day to watch a middle-

the screen is low-cost 45 euros but the picture is beautiful.

In the future, wants to cover the screen ink used for marking fields and streets which gets reflective properties, once I've done the work screen 3x3 meters and HX300G image was incredibly bright I think that now with PA70G will outright stunning. : D

Focus dial normally reaches its end position which also affects the deterioration of sharpening for just the one hole will be a tad less milled and lock the lens in one of three consecutive axles 2 axles will cause deviation from the axis, which affects the sharpness of the lens so want to move them at least 1 mm to Proper sharpness inside to the middle was not the end of the turn of the dial

I wonder whether via FANTEC 3DS4600 can play 3D movies via HDMI DLP Link technology, because I have no information whether this device can enable 120Hz mode via HDMI and as you know PA70G 3D mode will not start without a 120Hz refresh rate

So buy an old sony or something with a really good lens and plop the PA70G inside it? Is there any way in the world something like this could work?
post #1164 of 2305
So, now sharpness is achieved before the end of the market but it is not a large supply I think that will be more convenient for me to have at least a 1/4 turn knobs to spare them easier to screen 200 "150" in case of need does not need to adjust to the size of 40 ". Rubber gasket is about 1 mm 1.5 mm, but that does not move to the base of which is to carry out some projects and reduces the close-up lens even more. So ultimately wants to remove the lump of plastic via mini grinders. analyzes which of the screws has a decisive influence on the deterioration in sharpener .

I have service manuals, HX300G is needed to PA70G and especially to PA75C because I already heads TU7300 tuner TV but do not want experiment of passive elements soldered to the motherboard random with some elements will not be much of a problem because it will be similar to those in the motherboard televisions: ), but to get such instruction is almost impossible unless you smile.gif we have in the ranks capable of hacker wink.gif


smile.gif I think that without any problems turning a housing of the projector and putting tripe gave to another would be to do something with it, even getting rid of the mirrors, prisms, and using the spring I will be at the disposal of old had a DLP projector Nec. but for now I think that it does not look so bad and leave my PA70G in this state because the image is for me to accept, and I will have to have a mobile it sometimes taking him to work.

I love you guys that are trying to communicate with us with the translation programs. You are trying to share info with us and insights, and it's like going into a circus and going into the room of mirrors. I know you guys are saying cool stuff but don't know exactly what, and I 'm afraid to open up my PJ and adjust stuff, if the translation programs says do this, but actually you are saying " whatever you do, DO NOT DO THIS or you could screw up your PJ".
Maybe someone that is is bilingual could write in english what you are saying.
Whatever you do, keep posting and sharing, it seems cool whatever you are saying.

Hi, I bought a Lg pa70g 1 month ago ,and I tested the 3D with Stereoscopic player and all nice biggrin.gif, but when I try to enable nvidia 3dtv play to play some games I cant do it frown.gif, someone achieved that ?
post #1168 of 2305
3DTV Play only works with HDMI 1.4 compatible 3D HDTVs/Projectors via frame packing. Recently checkerboard was added as a supported format in 3DTV Play.

Frame Sequential is supported via 3D Vision, but you will need an Nvidia emitter to enable it. Also you'll need to use the EDID from a 3D Vision supported projector for an override, since the PA70G in unsupported.

I calibrated my PA70G last night and today (for fun) added in my Darbee Darblet... takes this unit to another level. wink.gif

I was getting 96" diagonal inches (16:10) with focusing range to spare. I had at least one turn to spare on the focusing ring, not this one. I couldn't get 98" inches diagonal if I wanted, the focusing ring won't turn, so it just barely matches my screen. I notice that even if I move the projector closer to the wall (8 to 10 inches) still the focus is all the way to the end of the focusing ring capabilities.
so now, don't know if I should exchange in case I need to use a larger screen in the future or keep since I have even focus...I'll decide tomorrow, I remember my old one could've done 120" easy. The focusing ring on this unit is tight, it feels like a focusing ring should, nice and tight unlike the wobbly ring of the other one. When I focus rotate the focus ring on this one the image doesn't drift/move like the old one.
also the image is about abot 1/2" higher that the last one, at exactly the same position. any thoughts?

My PA70G seems to reach infinite focus at anything farther than around 10'. Meaning, similar to a lens on a camera, at certain distance out from the lens and farther, the lens focus does not need to be changed - everything stays in focus. If you haven't already, you might want to execute a test projecting a 120" image, because it might be in focus the same as your 96" image, without having to adjust the focus ring.
