Sorry, but my question is that if you can't find it on any LG websites or anywhere else, how would we know about it?
If you purchased it new in a box, then I'm guessing it's not an old model. Since most of us on this Forum are in the USA, it must be a model specific to another country. The LG website in the US shows an LG 37LD460, so I would assume it's pretty much the same model as the one you have with just a different number.http://www.lg.com/za/tv-audio-video/...tv-37LD460.jsp
Actually, in checking further it appears this model may be specific to Asian countries. So, I still don't know the relationship between the LD460 and the LD461. Sorry.
