We use RTI control with Sony TVs a lot. In the last couple of weeks we have two customers lose RS232 control after firmware update. We have had other cases that were resolvable with a factory reset and turning the RS 232 and Simple IP control on. In these cases nothing has worked. Sony and Rti have not been help in resolving this issue. Anyone else bump into the RS232 stop working. If not RS232 what are you using to control Sony?
