from what i hear you have to go to a real store to get the low price, only in the store can you get the deal.

I also hear ppl are buy low frys price then resell on ebay and the like.

It just went back up. It was at $449 on the website for months. I'd wait.

Any comment on how this projector compare to certain TV's ? My main goal is gaming on around a 120 inch screen but hopefully the picture quality is good enough for watching 1080p movies and TV shows.

I was also thinking about this tonight with the release of the Wii U. I was wondering if games look as sharp and clear on this projector as they do on say a lcd tv.

I picked up a Viewsonic PLED-W500 recently, which is a 500-lumen version of this projector (it actually plays movies closer to 300 lumens according to reviewers). I believe this LG projector uses the same chip (.45x DMD LED DLP) but has more lumens, so it should produce a brighter image. My 500-lumen model is pretty dim at anything higher than the 80" size and also in anything other than a very dark room. I'll just do a quickie review of my version:

* Small (smaller than a piece of paper, less than 2" high)
* Cheap
* Shoots a nice-sized screen (max 80" on my Viewsonic, although I've used it up to 190")
* More or less requires a light-controlled room; does the best in a pitch-black room (extremely dim otherwise, at least on my 500-lumen model)
* LED bulb lasts forever (no more $99 - $399 replacement bulbs, yay!)
* No heat impact (gets warm, but not hot - my old bulb projector would actually change the room temperature)
* Great contrast (live-action film looks awesome)
* Under 80" in a light-controlled room, side-by-side with a couple of $2500 Home Theater projectors I tested, I couldn't tell a difference in quality, other than the bigger projectors were a bit more vibrant on CGI/cartoon colors (tested against a 720p Panasonic AE2000 and a 1080p Epson 5010)

yesterday i tried to fix the focus problem, tried for hours, and one of the 3 screws damaged(the one closest to the heatsink and bottom) because they are quite tight and i tried too many times and not careful enough, and that screw is blocking by the len, so the screw driver can't have the best contact with it .

i don't think the screws are designed to adjust the focus, the len does get loose when i twist the screws, but does not move the exact space/distance ratio as i twist the screw. (actually i think they are just for tighten or loose ONLY, not for adjusting.)

i want to say this problem is worse than the vivitek qumi warm up problem. this is my first LG, been used Acer k11, Vivitek Qumi, Viewsonic PLED-W500.

anyone have a better tutorial for the focus problem? now i only have 2 screws left for twisting.

I've had my PA70G for a few months now and this past Sunday while watching some football games noticeI did't have a focus issue at the bottom right corner. Before the station's logo that would appear at the bottom corner was blurry, not now.

So did this thing over time adjust it self ( the heat loosen something). Will check again.
post #759 of 2305
I just got two of these babies, but I am a little disappointed that there is no way to 'zoom' (is this normal for projectors?). I have a PERFECT spot to mount them, but its about 4 feet 'too far back', which causes the image to get TOO big. Is there anyway to add some kind of zoom/lense so I can mount where I want to? Otherwise im going to have to have a GIANT arm dangling from my vaulted ceiling in order to get them in the right position frown.gif

Halp!

Hi Follow this thread because I bought a week ago LG PA70G but has the disadvantage factory was described by many of the focus, were a little interested and that I have for you some guidance as tomorrow my projector back to the store because May I replace it or fix it, I can not them try out. Have you ever noticed that it is inside the lens aperture to limit light that is falling below the screen? Because I do! and what is worse, it is badly positioned.The projector produces image horizontally! CHIP DMD is horizontally! Why is that? aperture is vertically on the right side of the lens (the left in the direction of projection)? Aperture to be at the lower edge of the DMD chip PA70G it covers the left side of the image. Do you now understand why the upper left corner you can not sharpen the image? If the explanation is not, so the photograph is used to change the aperture depth of field. Aperture closed great depth, aperture open small depth, so if PA70G hidden behind the left page of the lens aperture lens caused no parallel depth of field, sharpness only linearly variable from large depths of the left and right shallow depth so it is impossible to adjust the sharpness in such a situation .I do not now if it does not fix the projector and give me a new one with the same defect that I will correct itself, but now for the next week I will have no projector before coming back with a guaranteeMy suggestion is to try all four unscrew the three screws holding the body of the lens and turn the whole 90 degrees in order to find herself in the aperture at the bottom of the lens I think that just rotate toward one hole clockwise and screw as long as 3 holes for the screws are evenly distributed if there is no possibility to swap the bolts remains undress and turn the lens aperture to the horizontal position at the bottom of the lens instead of his right.I think that is a whole different philosophy, and there is no logical explanation for this and it's the iris image should not be sharpened evenly over the entire surface of the screen and not as it is now the right faster than left later.Sorry for my English but I use google translator :DDDD wink.gif


the picture you can see the aperture is at the bottom and should be

Im having a nightmare trying to mount my projector frown.gif. It seems like unless the projector is DEAD CENTER in front of the screen (keystone set to 0), I have trouble focusing the corners. If the keystone is too far from zero, I can sometimes get three corners to look good, but one is always blurry. Has anyone else had this problem before?

I know using the keystone/warping is naturally going to lower the picture quality, but how can it be avoided when there is no way to zoom the projector? If I mount it at eye level with the screen, it would be right in the middle of the room!

Just got mine in from the UPS guy smile.gif Buuuuutttt....

I think I may have made a major mistake though... It's very cold here outside (around 0-1 degrees centigrade) and when I got the package in I opened it all up immediately and condensation started to form all over the lens and projector!! Arrhgg! I guess this will be happening inside it as well?

Can anyone tell me if I have screwed it already? I really hope this isn't going to cause a problem.

What should I do? I'm leaving it out of the box in the air hoping it'll dry quickly. How long should I wait before using it? 3 hours? 24 hours??

Thanks for any help with this.

Put it to the heating for few hours and then run it.

Thanks for the tip - but is it definitely safe to put it above the heating so soon?

The condensation is starting to go, but I fear there will be some inside so maybe this is a good idea.

I'm putting a radiator on low, and putting it on top of a box a few inches above.

Hi for explain how is problem in PA70G



I turned on the projector as soon as possible before he could moisten smile.gif warm during operation, and it was OK

Pawel, it is very good idea, give it a try and turn your lens for proper position if you can.
post #768 of 2305
Now my projector is on its way to the store in which I bought and waiting or sent back to me, or else will be repaired smile.gif So for the next few days or weeks I can try out my theory smile.gif as soon as I come back to the projector, and it turns out that will continue to be a problem with certainly tweak the focus of the lens and rotate the body so that the aperture was at the bottom smile.gif.If this works and the sharpness will change at the same pace over the entire surface of the screen and the sharpness will Idel in each square centimeter smile.gif sure to hear about it first.  If my improvement will operate'll try to do instructions on how to accomplish this.If you can not rotate entire body with screws I will be forced to undress on the part of the lens and set the aperture itself in the correct position.
post #769 of 2305
I DID IT. $399 SO I JUMPED ON IT at fry's. This is my first projector ever. Let's hope this exceeds my expectations
post #770 of 2305
I'm sure it will. My first and current projector is about the cheapest lowest lumen pj you can get by with, an Optoma PT100 with 20 standard lumens and 50 in bright mode, an no telling what it is actually, 5-10 lol??? I use it in my office and shoot the picture onto the opposite wall over my computer desk at about a 65" picture. With the single window covered, it's actually pretty fun to watch so I'm sure you'll love the little LG.

I'm tempted to get the LG myself but have very specific mounting requirements so I'm not sure yet...

Enjoy!

post #771 of 2305
guys, sorry but this projector is utter ****.. I have made the purchase via a friend in US and he brought it unopened.. If I was there, I would have returned it immediately.

Focus issue, unbelievable.. how can they dispatch an item in this situation.. I tried to adjust the screws but they were tightly screwed and didn't even move.. and moreover the lens cover is not fixed, it moves around when you poke it and it greatly changes the image produced.

My suggestion is to stay away from this unit, it ruined my two days and 550$s.. don't let it do the same to you..
post #772 of 2305
I understand you well is the biggest defeat LG as they could so botch this projector but I saw pictures of interior lighting and layout PA70G DMD and compared to PB60G and I know already why LG designers have earned a mistake, PB60G PA70G little brother has DMD on the right side parallel to the axis of the lenses so teeth image got out of it by the first lens is reflected in the prism and directed to the interior of the lens, and there they found the problem because the distance from the right edge of the reflected image to the left edge is different and diagonally at which the lens is set teeth now passing through the lens image was sharp both sides have to change the aperture sharpening, and I think they forgot PA70G August and applied the same layout of the lens but PA70G DMD is perpendicular to the axis of the lens and does not require changes in the depth of sharpness because passes through the lens parallel to the lens. The only reasonable solution in this situation is unscrew the body of the lens when the projector and rotate it around its own axis by 90 degrees so that the aperture she found herself at the bottom and check for an image is evenly sharp. If so, then you either have to perform new holes for screws or spread out and put together a lens aperture so that she found herself at the bottom and screw in the back.  I do not see any other projector, and will do everything that it works properly smile.gif is so bright that it is worth it to work out. LG has focused attention on the appearance of the projector and forget what this is all about, not about appearance but about functionality.Now my projector is in the process of warranty claim with my suggestion to remove the problem from the field, if the projector and corrects me forgeting what suggested that everything will be ok and it will show the result.If you decide to send me a new projector with the same defect smile.gif I'll do it this time are for her removal.

Design flaw ? or Production flaw where these crop of units didn't get proper quality control and was just sent out the door as is ?

I have the LG HX300 and no problems with the focus.

I wonder if I can swap out the lens from this and into the LG PA70G ?
post #775 of 2305
If the screw holes are evenly spaced and could be turned 90 % then this would hopefully be a easy fix.

Maybe on top of the aperture place in the wrong position but also the torque on those screws were torqued wrong ?

Perhaps the person who torqued those screws torqued it so much that it warped the plastic and metal ?
post #776 of 2305
You almost would have to get in there and use some type of flexible screw driver.

I guess taking the whole lens and lens housing is out of the option ?

Looks like you would have to remove that top circuit board or at least move it out of the way.

Remove the focus turning knob.

Remember ? if the screw is difficult to turn they may have put a little of some kind of lock tight on it.

Lock tight is used in automotive to keep certain fashioners from vibrating lose.
post #777 of 2305
Would a L shaped screw driver word in that tight spot ?

Or a dremel with a elbow attachment with a screw driver end on it ?
post #778 of 2305
focal length of the lens would have to be the same so I'm not sure HX300G lens fit to PA70G. It's about the distance from the lens to the DMD chip is just experimenting. Disadvantage? toyota why not once let go of thousands of cars on the market with a defective gas pedal! smile.gif can make it to if you do not give Focus of adjustment that is a fact! or not? And if everyone who buys this projector without exception, writes here of the May issue of Focus! This is not a factory defect? I wrote to LG POLAND and welcome the opportunity to Adopt Meile with my thoughts and suggestions, I am waiting for their answer would probably not have a problem already after the first email to me smile.gif Thanks for the correspondence and posted write to let the teeth and send them clues as to whom it will be communicated to you .Still chose not to my projector and I do not know if the screws are locked LookTitem smile.gif as I get back on my projector is going to turn out, I have a lot of precision screwdrivers to special screws and see. I just noticed some irregularity in which you need to gather facts and put together everything together. As for vibration when shooting stroke factor screw image I noticed it too and is another proof that the LG affair collapsed because it was not a single case I was also PA70G HX300G before and know how to work optics in HX and I am concerned about what is in PA. But it depends on me to have this projector and so I will use it for so long buried in the optics on the Fix this problem.The lens is in the form of pipes so easy to make a mistake and it put together so that something will be rotated to look at the shake as I will have a projector in the hands of the next week it's not possible because it is in Servisi repair, the shop where I bought the projector.I do not think the LG checks each projector on a production line that displays the image on the screen correctly 100 "I might check the individual circuits before assembly and in the end probably just turn on and check that turns on and you can see the image and the dial revolves at a smaller screen probably can not see inaccuracies in the Focus and now becomes aware of how you get projectors for repair under warranty.



The technique used PA70G TRI-PRISM and the council can not use the lens of HX300G. These are two different lenses that PA is more complicated. Until you come back my projector and the lens gets nothing more I can say except that I am convinced of the need to rotate the lens 90 degrees around its axis.

Czesc Pawel,

you are probably right, but I have doubt about how can you fix easy. Here are many people suffer a simple unscrewing, but to drill a hole for screw, or disassemble the lens tags it is not easy.

Yes, LG made a mistake, because PA is "unfocused", and must fix by factory, but fortunately it is not too serious, that's why the factory could not detect.

Anyway, I can live together with this "unfocused" unit for film, but if you find an easy fix I will do that. smile.gif



Here in Europe, we have pay for one unit, about 800-1000 USD,
in Korea this unit about 1000-1200 USD,
in USA 400-600 USD.

So I'd like to ask the unsatisfied and pampered trolls, don't flame this thread day by day.

OK Tataniko smile.gif Tomorrow I'll push it to service shop asked me to either new or fix current projector, I'll try to look at this lens so as not to make important traces to keep the manufacturer's warranty which will not be easy, if you really do not give a screw wring out, looked at the same site lens and it is possible to unscrew the front lens and hub to get to the middle group from the front without removing the focus ring, that was probably the best solution, but demanding sterility gloves and any metal tools. So as not to stain your anti-reflective coatings on the lenses, you might want to have a set of photographic lenses to blow. I'd rather not disassemble smile.gif but do what you will, but particularly in the simplest possible way. I first unscrew the lens from the body and rotate it without screws to test the theory of aperture and then I will deal with how to turn the way accomplish. If it will be necessary to drill new holes because you can not undress in the lens is at most will do the stencil with 3 holes to screw in a position now where 3 holes and bore a new one. Template to print and stick on a piece of plastic or plywood or cardboard. If you miss the new holes will remain just get to the lens when someone pieced them into a single unit that they can be dismantled periodontal smile.gif by the way why is this picture is moving in the making of the stroke factor screw focus
