Es5500 not dscoverable after Firmware update

Hi I updated the firmware on my TV last night to version 2000.2 http://www.samsung.com/uk/support/model/UE40ES5500KXXU the serviio option now no longer appears in the sources list. Serviio console can discover the TV and there is a green dot in the status with the correct IP address. It was working well before the firmware update. I have tried both the basic DLNA and samsung E/F profiles without luck. Is there anything else I can try?

Anyone? Or do I have to delete all my files and get a DVD player?

Have you removed the TV from the renderer list in Serviio? Try it and see if it's rediscovered.
Other than that, see if a detailed log sheds any light on it.
