Default [Q] SM-G900F makes Sony TV reboot

Hi there,
I have kind of a weird issue. I recently (3 weeks ago) I bought a Sony bravia KDL50W805BBAE2. All was fine with this TV until I received my SGS5 yesterday. After I started the phone and update all the Samsung software I started to notice my TV began to reboot suddenly. This occurs randomly, sometimes every 10 minutes, sometimes not for hours.
The reason I believe the SGS5 is causing this is because when I turn off WiFi on the SGS5 this behavior stops.
I have tried uninstalling the updates of AllshareCast Dongle S/W and turning off auto update. This seemed to have solve the issue, however it reoccurred after several hours.
I'm totally lost for now, I don't know what else I can do to break down this problem and find out what is causing this on the SGS5.
Any help would be much appreciated.

Cheers Ronald
