As a happy owner of a Sharp Aquos TV, I really hope Sharp can survive.
In Japan, Sharp is the only brand of TVs with both Japanese and English menu settings.
My 3 year old Sharp TV even has an RS-232 port that I have connected to my HTPC and I use it to control most things from it: power on/off, change input, volume, etc. The TV even came with a manual describing the protocol, what else could I ask for?
I have checked their newer models and unfortunately they have removed this feature. I am hoping to find some similar control capability via the network port, with an open protocol, but haven't found anything yet (I welcome any hints!).
The only thing my Sharp TV doesn't do well is displaying the image properly when using nouveau, but since it works well when using the nvidia driver I'm not sure if its a buggy EDID implementation from Sharp or nouveau.
