Unfortunately all the information I listed on my YouTube video is all the information that is available with this TV! I have also tried searching for them, but to no avail.
It was purchased about six months ago from Coles or Woolworths (some Australian food supermarket) during some special deal, for $299AU. My friend's mum bought it for her caravan, since it's an all-in-one DVD/TV/Monitor sollution, and it's also 12v compatible for running off a car battery. Since she never goes on holidays though, I asked if I could borrow it just for a few days to test it out, and that was a couple of months ago (ssshhh).
I dread the day I have to give it back, because I haven't found anything as awesome as this screen anywhere since.
It's from China, like nearly everything sold in Australia, so maybe that's where we need to look.
