I have service manuals for HX300G see if there is something about the brand of the lens

There is no info on the lens, but it is to change the firmware, as if somebody got the idea of feet smile.gif xxx_flash.epk file type, eg smile.gif PA75_flash.epk this info please!

Actually it was DLPProjectorfan that added that useful information. eek.gif
post #1417 of 2305
Are there any PA70G owners here who have also owned or used an Optoma ML500? I have the ML500 which I bought used some time ago. Generally I am happy with it apart from the rather soft focus and the fact that it is quite noisy even in eco mode. How does the PA70G compare?

t looks like the. PA70G OS is based on Linux. smile.gif I was given post passive components, and I think this week I will be soldered to the motherboard. If you do not miss anything, we'll see if that works DVB-T, as a SMART TV I think that will be more practical in use Android Dongle, with keyboard and mouse than the Magic remote. You can always change the Android and OS PA70G, already difficult. I tried XBMC as a frontend for Ubuntu smile.gif and it's OK.
Canonical introduces Ubuntu for smartphones, UbuntuTV so there are always solutions much better than smart TV.
post #1419 of 2305
First thing I do when I get mine is changing the firmware to Ubuntu TV wink.gif
post #1420 of 2305
Analyzes picture PA70G motherboard, and diagrams LG TV motherboard, and symbols resistors, and capacitors, the two are identical, so just to read no such C250 it will be, 0.1 uF capacitor and solder it in place, marked on the motherboard PA70G as C250. And I thought that without the scheme PA70G, will be harder to mount smile.gif This DVB-T tuner.

I need to practice your soldering SMD 0402, because they are so small the hot air soldering is impractical, you need the hard way by hand with the use of jeweler's loupe. smile.gifsmile.gif Or webcam to adjust sharpness.

What useful information ? eek.gif
post #1422 of 2305
Hi Pawel Dubiel, sorry I have not been on here in a while.

I am still trying to get my car fixed can only afford to fix one thing at a time got a bad intake gasket on my car that caused the coolant to go into the oil eek.giffrown.gif but I caught it in time and saved the engine from more damage.

I won't be able to afford a LG PA70 G or any projector at the time so I better start saving up after I get my car all fixed and running.

Pawel ? do you think that later production LG PA70 G projectors would have the focus issue fixed by the time I buy one ?

Lets say in March ? April ?

Has anyone found out or bought one of the later production LG PA70 G's will no focus problems ?
post #1423 of 2305
Just joking Rugrash.

I am not sure I will have to go back and look at few of the posts and see what information I posted.

Hope you and everyone is having a good new year.

Wish I can win the lottery then I could fix my car totally and buy another one just like it.

Also I can buy Panasonic's new Laser Led projector.

But the price is way out of my range $ 5,000 but it looks like a nice projector.

hey man, hope you get your car fixed, Im waiting to win the lotto too but since I don't buy tickets, it might take a while....I hear that the 2013 model of the PA70 will have an optional HD tuner, and hopefully no focusing issues, but knowing LG, I wouldn't hold my breath on the focusing issues. I may buy one if it goes on sale again @ frys but im like you, just finished replacing my radiator in my civic hatch, we'll see...happy new year to you too man:D

In my opinion, LG did not make any changes in the lens, I see the pictures of Korea, the PA75K has the same aperture optics built on the left and below the optical axis of the lens.
LG Poland, responded informed me that the factory in Korea, but that ended.
From my experience is that after the treatment I have sharp image at 99%, I can say that governing with screws, also obtained in each edge sharpness of the image.

The problem is that, now as if the picture is sharp, but still in the middle of the picture is less sharp, it looks like the lenses are poorly selected or diameter of the lens is too small in relation to the surface of the DMD. Watching movies, do not mind, but when the text is longer it can be seen, so PA70G suitable for watching movies, less for business presentations.

What is your car? a little strange that the water was getting through the intake gasket. I said the sooner the engine head gasket, but if the oil had turned sour cream, it's got water or coolant.
post #1426 of 2305
There are PA70G's out there with good focus...



My current (3rd) unit is like that on about 98% of the screen (this is on a 100" screen), certainly as good as should be expected in my opinion.

I have seen worse focal uniformity on projectors costing much more.

If you get one that you are not happy with definitely exchange until you are happy, I did and it paid off.

PA70G does not have a TV tuner physically, but the same projector PA70G after installing a TV tuner it already called PA71U or PA71K.
LG is not provided for PA71 to europe so there is no PA71G.

PA71 .... K. .... - KOREA
PA71 ...... U. .... - USA (U.S., CA, MEX)
PA70 ..... G. .....-GB (GB, EU, etc..)

So our PA70G the united kingdom GB version, and does not have a TV tuner,
in the service menu you can change the region on 02 and then PA70G is already PA71U so the projector in a version for the USA, CANADA, MEXICO. It has a TV tuner, but only in theory, because there are no parts on the motherboard, I'm trying to mount them.
If I succeed, and after mounting the projector, turn on and it will work, I change my PA70G in PA71U. The disadvantage of this solution is that the menu will be available only in English, French or Korean.

This is not a problem because even in English is very easy to use.

My first (and current) unit looks like this across the entire 130" I'm projecting. If I want to see pixels I move in close enough and they're there wink.gif I must say that the screendoor is MUCH less pronounced on the PA70G than on the 720p Dell business projectors at work. I brought those home a few times for movies and the inter-pixel gap is much more visible and darker. That could be a combination of a better lens and an older chip, but even from my seating position 10ft away I could still make out individual pixels. On the PA70G there's no chance of that, I can only detect some faint stair stepping on small text, but considering that it's not pixel mapped those could just be artifacts. For video the slightly soft lens actually works to its advantage, creating an unintended "smooth screen" effect biggrin.gif

You mean the 70 model and not the PA75A ?

If I had more money and find a LG PA 70 G cheap on ebay and find parts from a old bulb based projector I would try experimenting with lens but them again it might be a wild goose chase buying parts and nothing works.

I guess if the lens are the same size and diameter and the screw hole line up someone could get a old bulb based lens with zoom to work with these projectors ?

I know on the Acer K330 thread some of use talked about building a Frankenstein projector from the Acer K330 by taking the guts from the Acer K330 and finding a old bulb based projector with a lot more room for heating.

The Acer K330 projector and the clone projectors suffer from heating issues and poor design of how the LED heat sinks are placed inside the projector.

I even said that the power supply on the Acer K330 is placed to close to the DLP chip processor.

The ventilation on those clone projectors is much to be desired.

However if the guts from the Acer or even this LG PA70 G projector could be placed in a older bulb based projector it might work ?

The LG PA70 G does not suffer from the focus heating issue as the clone projectors do.
post #1430 of 2305
Not to get off subject but my car suffers from GM's infamous intake gasket problem that effects millions of GM cars with the GM 3.1 L 3.4 L and some 3.8 L engines.

Pawel ? I wonder if a old lens with zoom from a old bulb based DLP projector with the same diameter lens and housing and the screw holes that would line up with the screw holes on the LG PA70 G projector ?

A Frankenstein projector ?
post #1431 of 2305
There is a article if you do a search called Smooth Picture Algorithm by David C. Hutchison.

It's a article that's a few years old and is for the old DLP projector TVs but I think it's the same diamond chip DLP processor that is in these projectors.

It talks about the diamond grid DLP processor.

where did you the PA71U model number? when will it be released? Im waiting for it but I haven't found any info on it. smile.gif

actually the "K" model is PA75K in Korea and it does have a tuner, so Im assuming the PA70G with a tuner is coming to the US but don't know if your model numbers are correct, I can't find anything on model PA71U
post #1434 of 2305
It is clear from, you will not find info about PA71U, because it does not exist, the LG did not produce this model and even more so for the United States, LG is not the official site in Poland but even PA70G sell them in stores, so the question how did they come from the Polish distribution, since the package do not have a description in Polish? which is punishable in Poland!

PA71U is a model who was in the plans, but it was probably abandoned, using the remote service, I change the region code of 17 (GB) to 02 (U.S.) and after the projector turns off and turns on, check the model in the service menu and I see PA71U and TV options smile.gif menu languages ​​are only for America and Canada

Sorry for the quality of pictures, but I have made a fast phone smile.gif

Thank Pawel, companies often use preliminary production models before they even build the products, for example the PB61U with a tuner here in the US (hard to find).. but in Korea it's labeled PB63K exact same unit 500 lumen with built-in tuner.
post #1436 of 2305
smile.gif Ok I has integrated TV tuner to my PA70G, works and does not work smile.gif, that is working analogue tuner, DVB-T does not work, no sound is analog, black and white image. I think the result is that the PA71U is the U.S. version and that is why TV does not work properly in the EU, or head TV which I managed to get is not adequate.

At the moment, there is no point in TV tuner installed in the European version of PA70G, maybe the ability to upload the software will be in the European version.

But I'm happy with the work that they do because chances are any modifications smile.gif, and after 4 hours of torture, mount components 0402, size 1x0, 5 mm, is quite some time fiddling around with my projector smile.gif



post #1437 of 2305
Glad to hear you got it working ... Sort of smile.gif.
Since you installed the TV tuner, I would assume that since your in Europe and the standard is DVB-T, the LGPA70G may be looking for an ATSC signal for digital video.

Can you put up a step by step instruction of what you did for your projector.
Maybe someone over here can try to replicate it and see if the ATSC signal will work with the new tuner.
post #1438 of 2305
You'd think that since Poland still broadcasts in analog and hasn't completely switched over to digital broadcasting yet, that you'd be able to get it work.

I looked at PAL wiki page and did see that it said "The PAL-N system has a different sound carrier, and also a different colour subcarrier, and decoding on incompatible PAL systems results in a black and white image without sound"
post #1439 of 2305
OK modified input in the head TDSS-G101D (EBL61060001), not bought a new head, because I had no opportunities, but I found a little money, removed from the TV, sell me service, dealing with the repair of TV, I'll try to find out, how this standard works head, maybe it's mpeg2, mpeg4 not. In Poland, a DVB-T mpeg4, assembly required several components, such as 1.8 V LDO build it first and checked the voltage, it was ok, then edited resistors and capacitors. At the end I installed, head tuner (HALF NIM).

I will seek information on the tuner because I think the production is a date 25/11/11, and I'm wondering if at that time it was already mpeg4 DVB-T. option (SYSTEM) in the service menu, you can not change too much, the pictures are a few of them.




Analog TV is not important, and so this year in Europe switches off analogue transmitters, the problem is to run DTV-I and the LG TV DVB-T set-top box works perfectly.

Tomorrow again will open the projector and solder some capacitors marked on the diagram as POTIONAL, I understood something of the scheme.
I was looking for information about this receiver, and he must act with DVB-T mpeg4 smile.gif

LG TV motherboard, a matrix, in which by means of resistors, it is agreed in 8 bits, states of high or low, they always decide on whether it is 3D or 120Hz, DVB-T2, and ther it is called MODEL OPTION, I wonder if there you do not have enough solder, would be handy smile.gif scheme PA70G

hey Garibay!
Thought you would like this! Fry's has your LG PB61U for 599. You were saying you wanted a tuner.
http://www.frys.com/product/7509106?site=sr:SEARCH:MAIN_RSLT_PG
This is the only store that has it in stock. If you want it you better hurry, the shipping option is still open.

p.s. although on LG page it says that is the full List price. There is a chance fry's will put it on sale, maybe even for 399. Who knows. At least they now sell them, so that is your best bet for good sale, when and if it comes up in the next month or so.
