Sony Bravia series IP control problems
We are having some trouble with Sony Bravia series using Simple IP control. The displays have a tendency to drop offline, and need a hard power cycle to come back online. The displays usually indicate their network connection is offline as well when this happens, but we've seen it happen both ways. There's some correlation between expected network traffic loads, and the displays locking up, but it's not consistent. We experience the most problems when the displays are in an SVSi environment, or on our biggest VLAN which has over 900 active devices on it. We've got multicast blocked on the ports that feed devices like the TV's.
We're probably going to backgrade the TV's to RS-232 control (in some cases using MOXA boxes or similar) to do an end-run around the problem. I have an XBR850 running RS-232 already, and it seems stable.
Does anyone else out there have any similar experiences with these TV's, and possibly any advice to improve their IP stability?
