Bony!
Thanks for taking the time and sharing your experience with us. And I understood what you just wrote.

Maybe post in your own language and then have translation program put it into english, then we might have other translation programs that might make it a little clearer to us.

Have a good trip. Sounds like it's going to be cold.

Hey, you can not fix this problem by using the screws can only improve little bit, but unfortunately this can not be changed.

Bony said the fix worked for him. Have you tried this yourself? Still cant get it to focus?

So thanks bony for the directions, but they are still a tad hard to follow. Has anyone tried this yet? We could still really use a detailed step by step.

*also bony - did you need any special tools, or just a standard screwdriver? And what did you use for the shims/spacers (or were you able to fix it by simply adjusting the screws)?

Let's wrong with turning the screws will influence the image you can not fix the lens but the image is still blurry but it will be in another area but that is minimal with the shape of the pixels will be correct, but they will be like giving a hazy impression of sharpness is not the longer terms and a projector heats the picture is clearer. Picture seems to be perfect but it is not because of the close Focus is on the lower left to the upper right side and less palpable in the very top left corner and lower right. Far back you notice the sharpness compounded by the bluntness of the upper-left corner towards the bottom right and it already does not change. Because the problem of screws are not understood a single projector but not 100% every one has the same defect. I exchanged in store for the new and the same as a drop of water is not the case that someone screwed something bad is just a bad designed projector. Proper optics changing sharpness over the entire image surface at the same time and not diagonally from the lower to the upper corner of the opposite. Displays the image on the 100 "screen and almost gets to the border sharpness maximum position (in HX300G I had a lot of inventory, and even regulate sharpness 5x5 meter screen on the PA70G I have a problem already at 100"

The picture is acceptable but again twirling screws will not cause a defect removal is still only less that you can see.

My first projector turned out to be an idiom in which someone already circulating so something had to sent him to the store and demanded the replacement of the new in a box sealed with tape originally by LG and turned out to be the image was acceptable in the previous picture was not always sharp for the most part of the screen in such a way that it looked like they double pixels

I can't afford to get a new projector anytime soon, once again car problems.
I might as well wait until next year and see what new projectors come out with 1080 P resolution and hopefully no problems with focus.
We can only hope friends that LED projectors will only get better in lumens, resolution, and hopefully quality.

I have also already PA70G LG home about a month. I am satisfied with it. I use it to play HD BRrip 720p and the picture is super to me. I bought it for the price of 530 euros. Has a better image than the projector BENQ W710ST I had until recently. I would give the photo but I do not have a good camera. I am from Slovakia. I do not know much English so I use google translator so excuse the mistakes. The projector will have the time until the LED 1080p offer some models for a good price.
What is your opinion on laser LED hybrid projectors? Ma team someone with experience?
I made a video image on the projector. image 80 "projected onto a white wall. 640x480 camera because of poor quality.'s just the idea.

So it looks like the LGPA70G was released sometime around April or May of 2012, can we expect a new version of this projector around the same time in 2013? I searched but couldn't find any info yet, just press releases for the LG 84-inch Ultra-High-Definition TV.

I think you just convinced me to go back to looking at lcd tvs. rather than going with bulb projector , led projector for tv. I thinking more smaller lcd and bulb projector for movies.

My thoughts exactly, I use my 42 inch hdtv 90 percent of the time, and for special events , special football game, or movie, or favorite tv show, will turn on the pro8200 and enjoy the big screen. I thought this 70g could take the place of the 42inch hdtv, but it can't, because of "focus" issue, and "weird" image problem, and the fact that you can't have any lights in room on, if you want to get decent image. I like having regular ambient light in my room when I'm watching tv, or surfing the web. I don't want to be in darkness all the time. Maybe next year will be the year for LED/laser , I don't know. Maybe the laser aspect will give the pop, I don't know. For 399 price, if LG can get the focus issue fix, it's not bad for a 720p If the "weird" effect doesn't bother you.

It's almost like you punch something and you can feel the impact, and it feels solid, on the pro8200. On the 70g , it feels hazy, ghost-like, no substance. I'm putting words on the effect, but those words are not exactly right. I get a good GUT reaction when I watch a movie/ game on the pro8200, but with the 70g it's colorful and all, but not "bright" or "punchy".

You're struggling awfully hard to express the fact that you're comparing a 2000 lumen projector to one with 700. The je-ne-sais-quoi you're grasping for is the simple difference in brightness, nothing more, nothing less. Of course a light cannon like the PRO8200 will throw a much brighter and punchier picture than the PA70G, there's no mystery at work there. I considered both and ended up with the LG because it was $300 less, money I applied towards other HT purchases, it still looks very good, and I can truly treat it like a TV insofar that I can turn it on and off to my heart's desire. However if a TV is what you want a projector will never be that, no matter how bright it is, for the simple reason that while whites may blind you, blacks will only be as black as your screen surface in ambient light. How black is a white screen with room lights on? Not very. Nuff said.

Regarding focus, my LG behaves exactly like you're describing and expecting: it goes out of focus when turning the focus knob either way. It is true that it has rather soft focus compared to many other projectors, and it seems to have a rather large depth of field which makes it look like not much changes when you turn the focus knob just a bit. For that matter I'm not a fan at all of the indirect and very fiddly focus knob, it's tiny and slippery and hard to get a good grip on. But then I look at how good the picture still is and remember that I only paid $400 and am smiling from ear to ear. Besides, as anyone who has followed this forum for any length of time knows, a lot of the old hands and pros like to ever so slightly defocus their projectors anyway, because after all we want to look at smooth IMAGES and not sharply focused PIXELS. But if it's pixels you want to see, by all means get something else.

As an aside, I think the $800 price point is a bit of wishful thinking on LG's part. There's nothing in this projector to justify that much--the LEDs have to be considerably cheaper than a bulb, and the optics are about as cheap as it gets. If they "deminiaturized" it a tad, moved the PS inside and enlarged the fan to make it quieter, they could have an LED HT projector they could sell for $400 - $500 and still make a profit.

Christ guys, here's an idea - Let's get a COMPLETE AND DETAILED TUTORIAL on how to fix the focus, THEN we can make judgements. If I had more experience with hardware I would happily make a tutorial myself. Yes of course the projector SHOULD have been 'fixed' before it left the warehouse, but there is nothing we can do about that now. If the process is a simple matter of tightening some screws, and there is a dramatic improvement in the focus (as many people have claimed), THEN we will be in a position to properly judge this projector.

So, can we please stop with the whining? We need somebody to post clear step by step pictures (perhaps even a video). I have looked over bonys pictures several times, but still don't feel it was quite clear enough.

I own other equipment, and so do you, lots of stuff.
Now on all that other equipment, if it has focus wheel, or something you can adjust to focus whatever it is, it goes one way, all the way and it's unfocused, then you turn it in the other direction until it gets in focus, then if you turn it past that point it gets unfocused again . Understand what I am saying so far.
NOW the problem with this stupid PA70G is is I turn it all the way to one side , it is unfocused, fine, then I turn it the other way, and it almost , not quite comes into focus and I can't go on the other side of the focus turning, it stops almost focused.
Can any of you guys turn it past that point and get unfocused on both ends of the focus wheel turning, I can't.
On my viewsonic pro8200, it acts normal with focusing wheel, around middle of turning it , it comes into focus, and if I turn past that point, becomes unfocused, so I go right to point, where if I turn one way it's unfocused and if I turn the other way it becomes unfocused. I find the perfect spot.
Guys, if you have this problem, or ever had this problem , CALL LG and tell them about it. I called them and tech person told me there are no reports of that problem that he can find. My unit was built in nov 2012. I was here a couple of months ago, and people were reporting this problem in this forum room. Did you guys contact LG about this problem. He said if they were aware of the problem, or if enough people complained they would change it. So complain, and get this damn PJ working. It could be good PJ if the focus wheel had normal range of movement.
Don't LIVE with this slightly unfocused image and tell others to live with it. Let's get it fixed. I mean , guys, when apple makes a product with retina display, razor sharp image, does it make sense in the year 2012 to have anything that is slightly unfocused and over time could screw with your eyes.
After using the LG PA70g for a few hours, trying to adjust everything, I went back and turned on my viewsonic pro8200 and compared movies and tv shows I just watched on the PA70g. The pro8200 blows the pa70g out of the water , not only on sharpness, but on "full image POP". It feels like solid image, the 70g feels off , I don't know how to put it in words. It's almost like you punch something and you can feel the impact, and it feels solid, on the pro8200. On the 70g , it feels hazy, ghost-like, no substance. I'm putting words on the effect, but those words are not exactly right. I get a good GUT reaction when I watch a movie/ game on the pro8200, but with the 70g it's colorful and all, but not "bright" or "punchy". Another way for me to put it is, say a game on the pro8200 looks like it's bright and sunny, looks about 12 noon, but same image on 70g looks like 6pm. It is imitating brightness but something is missing, hard to put into language. The pro8200 has "punch" or "pop", and the 70g doesn't. I want to like the 70g, it has a lot going for it.
I remember others a few months saying the type of stuff I'm saying, they too were having a hard time putting the "effect" into words too. It has a "focus" problem , but it has this weird image problem, that some of us have a hard time putting into words.
So test your unit, does it come into focus around middle way in turning YOUR focus wheel, or at the very end of one side, and you too feel, it's almost in focus, but not quite.
Is it defective? You tell us. I think so.

I agree, the PA70G is definitively defective, I bought locally and used for a few days and didn't notice at first, but when I tried to use my computer and had text on the screen, it was horrible, and Im not talking about the diamond pixels, the focus was so uneven, at first I tried to live with it but it was just too ridiculously bad. my fist thought upon trying to play with the focus ring was " LG built a beautiful projector with a .99 cent lens" it's a shame to have designed such a great machine and cut corners with the optics, I will wait for the 1080P machines and hopefully LG has learned a lesson. other than the focus issue this is stellar projector, so much potential, so sad

I think that you would have to do a massive attack us at LG teeth have realized that the people do not squeeze worked version of the product without notice of a dud. I do not deserve to affix the reddot design award winner 2012 on its packaging. The projector is designed especially bad lens also have reservations about the use prisms and I think are unnecessary when used in this model finally DMD is the objective lens and not enough for his side so that the deformed mirrors that do not light like a prism. Some shops just asking for this projector up to 900 euros for something that comes from the factory with a defect? Let LG to realize that if something does not forgeting this will have to be reconciled with that of the LED projectors will lose market because people do not forget a smile.gif and it is difficult to rebuild trust. PA70G is a great projector, but must make a correction in optics without it is rather an imitation of the projector.

Diamond pixels LG is another error but that is not likely to correct the possible need to replace the DMD when compared to HX300G PA70G image looks like it has less resolution than HX300G. Instead, it looks like 1280x800 800x600.

I already sent an email to LG POLAND with comments on PA70G.

Have done a test and trial modifications, but if I were to separate the lens from the projector. Unfortunately, I can not because my sutrace guarantees and if it is worth I have electronics fail.



Make a simple experience, position the projector screen on the left side rather than in the center. Turn on, and set so that the image was on the screen, of course, will be trapezoidal and distorted in this position but Pay attention is focused on the entire surface. Inside the lens aperture changes the depth of field but need vertically from top to bottom because the projector is on the edge or on the bottom or at the top and the lens bends the image that was the proper shape and therefore also need to bend the lens depth of field. made a mistake and turned the lens 90 degrees, and so instead of bend in the vertical lens bends the beam in level between the right and the left, now you understand where is the problem?

Lot of new generation Pico HD high lumens led projectors have focus issue, because it's bad design.

I owned Qumi Q2 and cloned Acer K330 (3x times), and they all suffered startup warming focus issue, but that was much worse than this, because first 10-15 minutes were unwatchable and painful. Under movie, nobody can not see any focus issue on LG, but If anybody check the text and corner accurate, then it is possible to discover this problem.

So, I have to say, this is not so serious such other LED HD high lumens projector focus issue, but if LG will repair it for free, I will be happy.

In PA70G lens is fixed, which means the projector works as the slides osotrosci adjustment takes place through the entire zoom in or out of the lens of DMD Chip. To the sharpness of the screen usyskac 100 "need to get closer to the DMD up and there is a small problem because the holes are too shallow slide milled and ends of the lens range was enough to feed a little rozfrezowac about half a millimeter deep into the ring and turn the adjustment of several teeth in order to reduce range with minimal screen and increase the scope for screens larger than 100 "after the expiration of the warranty smile.gif I will even if it had been modified and the projector lens and the guide sleeve. another way was to tweak the lens removal and grinding rubber seal fixing positions guide seals.





Turn the lens to the correct position would have worked too but you have to drill three small holes in the new positions of the problem is that the threaded screw holes I find it rather small tap is not possible. The same performance is also complicated pinhole surgery demanding a large selection of precision drilling sites is not a problem because I just unscrew the three screws of the white sleeves a little slide to eject them came out of the bushes Turn the milled recesses of the lens to the correct position of 0.5 mm drill bit to mark the holes in white the place of performance of new bushes. For milling cavities would have to use the grinder on stand DREMEL drill. Or ask around for some watchmaker if he could perform three threaded holes for the three screws at the marked locations instead of fresowac circular depression can be sanded flat with a file on the Surface so that precise white sleeve is not swayed.

I guess you don't have to drill the unit, just need a ring like a washer with proper holes with same diameter of lens, fix the ring on the original holes and you can turn easily your lens on the ring. This is like a lens adapter, bayonet of LG. smile.gif

After another week with the unit I have to revise my adjustment advice from earlier slightly. Definitely perform the guided Picture Wizard II, but for added brightness or "punch" you can use a Dynamic Contrast setting of Low or Medium. I wouldn't go all the way to Maximum because the colors definitely turn a little strident and grotesque and you lose a lot of subtlety in shading. But even on Medium you still get pretty good dynamic range and the picture is very much brighter than with it off. In fact you get A LOT more effective brightness from staying on medium lamp brightness and setting dynamic contrast to medium than from cranking the LED brightness all the way up. Right now I'm throwing a roughly 140" picture (haven't measured yet, just a guesstimate) picture on a white wall (ceiling white for now during evaluation), and with the "lamp" set to medium and dynamic contrast to medium i get a very bright and "punchy" picture in a dark room. Shadow contrast is still quite good, dark color gradations are still distinguishable and not completely squashed to black.

I must say that I'm actually preferring the diagonal pixel matrix for video. While the edges of the screen do look comb-like from up close that disappears from a few feet away, and almost horizontal or vertical lines (e.g. poles, door frames, buildings, car roofs etc.) which usually lead to stair stepping and flickering are a lot smoother. In fact this projector throws a very smooth, film-like and pixel free image that often makes me forget that I'm watching a digital image. And all for $400--wow!

Received my projector yesterday and very pleased with the picture. This is my first projector and I was going through all the menu's just messing around with the settings and learning. I had RBG connected to windows and came across the Zoom, I shrunk the video I was watching, and also came across 2 choices of resolution. Somehow I lost those choices and spent a lot of time searching. I used Win XP Pro, Ubuntu, and Vista w/HDMI (which freakin rocks btw) and don't have the choice. I found 2 ZOOM's in the Ratio menu, Xoom @ Cinema Zoom, but they are not available to tick and adjust.

I need help if you know what this newb did to cause these not to appear.



Thanks

P.S. so far even focus / beautiful picture

So to date the best tutorial we have (for correcting the uneven focus issue) seems to be this one...

http://www.avsforum.com/t/1304775/vivitek-qumi-led-1280x800/1800#post_21450953

Has anyone tried the above steps on their LGPA70G? It sounds like a simple two step process - 1.) Crack open the case (4 screws on bottom). and 2.) Loosen the two accessible screws on the lens, wedge a shim in one corner, and tighten everything back up.

Sounds so simple, but since this tutorial is for the QUMI I am a little afraid to try it... Please report back if you have any luck!

If we could just get EVEN focus across the entire image, this would be an AMAZING projector even at full price...

I own LG PA70G for months but I dont understand of following things:
1) Why the many items in Picture settings are greyed and I cannot change them???

2) "Still" function on remote works just for few minutes. After few minutes it will stop being in freeze. Why??


Somebody of you know solution please?

When PC is connected via HDMI with 1280x800px resolution then many settings are greyed. But I discovered following thing: When I change resolution to 1920x1080 then all settings aren't greyed. I really dont understand it..

Ok, I just turned on my pc and I'm using hdmi.
Although some settings are greyed out, I can still click on those settings and it opens up and I can change those settings.
Check to see if you can click on your settings, I'm trouble shooting with you, so we both can learn.
Name a setting that is greyed out, that if you click on , it doesn't OPEN up and you can't adjust it.

For example, in audio everything is greyed out, and I Go to SOUND MODE which is bold black, but all the settings under it are greyed out. :standard is grey out and all the ones under is are greyed out, and I can click on each of those and change it, can you?
