TV UE55RU8000UXXU worked fine for 2 years. It auto updated to software version 1420.0 and I now can’t open apps, if I mute the TV I have to reboot the TV to get audio back.

all apps apart from YouTube won’t open, I have tried factory resets it fails everytime. I have rebooted the TV, network router, nothing fixed it.

I own other Samsung TV they all fine, I have no internet problems at home just the TV had become unusable since update 1420.0.

I phoned Richer Sounds as I purchased TV from them, they said Samsung are aware, but how long do I have to be without a TV I can’t use???
