1.5.2 on OSX not visible to Sony KDL-42W829B

Hi, I removed 1.4 from my OSX iMac and ran the installer package for 1.5.2. The console runs fine. It says that the server is running. The library seems to have refreshed fine. But Serviio is not visible to the Sony TV any more. I have tried disabling both OSX and Router firewalls, but this makes no difference. I tried to locate the Serviio server process itself, but can not see it in Activity Monitor. Sorry to be useless. I am not an OSX expert and would appreciate some advice.
Thanks
David
