I purchased the Lan to Serial adapter available from this website. It arrived crazy fast (thank you) and I set it up last night. I’ve got a very basic setup at the moment. DTV Receiver, AppleTV and the above listed TV. I added the “All Sharp” TV via the adapter and it seemed liked everything worked beautiful. All buttons work as they should. The one hang up I’ve run into though is that the TV won’t power on. It powers off just fine, and it’ll even power “back” on if the set has just been turned off, but anything more than 15-30 seconds beyond last shut down, the TV won’t power on. This is via both my setup activity and just merely hitting the power button.
