Kind of late I guess, but I've always found that LG seems to have pretty lousy QC on their products and they break a lot. Like BenQ projectors, you get a nice image, but at the end of the day (week/year/etc.) their products break or are defective far more often than a Panasonic, Sony, or Samsung typically will be.
This is a huge killing point for LG for me personally, though I've enjoyed the appearance of their product, I've also had two or three guys at work who have had their LG panels fail, while my Samsung, Sharp, Pioneer, and even Sampo keep running strong.
