We resolved one of the problems by switching to IP. Our programmer checked and the tv was responding to the commands sent via RS232,but no change in status. Works fine with IP control The other Rs232 situation doesn't have an Ethernet cable at the location. I send a note to Install Support at Sony and they are forwarding it to engineering for evaluation. If anyone else bumps into this let me know as Sony hasn't heard anything similar from other dealers.
