Hello,
I've just bought the projector a month ago, and so far, I am satisfied with it.
The brightness is good (I always use it with min settings), the color palette is quite ok, and there are a lot of adjustments to get natural colors even when you are projecting to a non-white screen (wall, for example)

I saw in the manual that the 4 pole jack connector can be used as composite video input, but the problem is that there is no standard which pin is connected to what.

Does anybody know the pionout ? I would greatly appreciate!

Cheers!

Hold onto that cable because LG uses a different and incompatible pinout compared to most standard versions that can't be corrected with a simple color swap. The input is designed to also be compatible with 5connect composite and their 3connect rca has an odd wiring and using a universal results in combined signals.

I have tested this now with several cords and three different devices that use them specifically. The universal cords and adapters work (one with swapped colors) with the other two devices but not the LG while the LG-specific cord works with the LG and NOT with the other two devices.

The LG works perfectly using its own cord though and detects sources just fine.

I had read reviews/comments that bulb projectors vary in characteristics over time, in brightness and color, as well as just burning out suddenly, so I avoided them. I wanted consistency, so I am happy so far with my LG PA70G, but I also am wanting to see better lenses, ones of glass, in LED projectors. The focus issue I solved by letting the projector run for 15 minutes or so, then focused it as well as it can, and left the focus there; now, I turn the projector on for 15 minutes before sitting down to watch, and the focus is stable because the projector is at stable temperature. LED DLP projectors produce an image that appears more like film to me, which is my reason for having a big screen (120" 16:9) anyway. The room is completely darkened, light-controlled. All my friends who visit and watch films on my LG PA70G LED DLP projector, as I have it setup, are impressed and enjoy the experience, which is why I set up the system.

I don't really see what all the fuss is about the focus on these projectors. to me and maybe I got lucky I have no focus problems on mine. most of the out of focus post/pictures I have seen is on very small text in the corners and that is from very close up pictures I have seen. anyway I feel for the price I paid ($400)for the projector I feel it has an awesome picture in a darken room via my ps3/Blu-ray or my directv hd on my 106in screen. is it perfect no ,but for the price and overall picture quality you get it's a pretty darn good deal. just my 2 cents

Hi, I have some questions:

1) What are the best glasses quality/price for a PB62G?

2) Is there a driver for 1280x720 120HZ for PB62G?

3) Has PB62G a Texas Instruments chip for 3D?

Thank you very much for the help.

I have this unit for a couple of hours now, and so far i am happy with it. Sadly i might have to return it anyways, because i have a strong whining sound all over the time...

I found out it comes from something vibrating inside the case, because when i put pressure on the top of the projector the whining dissapears, when released, it starts again...but heavy pressure is needed, just a book on top will not do the job.

Has someone an idea how to fix this, otherwise i will have to send it back, i really can not stand this high pitched whining sound, the fans are no problem, they are not very loud.

Can you provide some extra info to make sure everyone understand's the issue thoroughly. How did you mount the projector? No mounting or tripod or mount? If you bought it from the store, then you can just take it and they can fix it there on the spot. If its through online then you may ask for a replacement.

It presumes that there must be a loose screw which vibrates, loose connector or something touching the fan blade or in its path. Open the hood and try to figure out where it is coming and see if touching anything with a wooden tooth pick can stop it.

Here is what happened in my case, I plugged a earphone to the 3.5mm jack and while trying to remove it, the end of pin broke and struck inside the jack itself which I couldn't remove by any means. Also I lost the sound in speakers. I bought this unit in USA and I'm in India when it happened and its just less than a week. The local LG service centre refused to service it as the product doesn't have warranty. I took a huge risk, with a other technician opened the hood and able to remove the broken piece out.

Thanks, but i discovered the high pitched sound comes from the electronics inside. Whenever the processor unit or whatever inside is working has to calculate something, it makes these sounds. Guess that has to deal with the variable power consumption and is by the way a general problem of lg electronics of various kind.

Already had to return other products of this company because of this. Some people like me are sensitive to these sounds, others don't or overhear it. And lg has this failure in all their projectors from scratch, already the hs200g had this problem, so I returned it.

At first I did not notice it at this unit, because at day there is more noise from outside, but in the evening, when its silent outside I cannot overhear it.

Only pushing on top of the projector to make the case very tight ends this, but I see no workaround to put the needed pressure on it constantly.

Picture was good, I gonna wait three more years until competitors and led projectors in general have improved and see if I am lucky then.

But for now, over 400 euro for a tinnitus sound machine with added projector is a no go for me.
