I am unable to use any of the HDMI ports on my Sony Bravia KD-55X8509C and also unable to get anything through the digital tv.  I have tried resetting the TV several times, unplugging for 30 seconds etc., but nothing seems to work.  The 'troubleshooting' on the TV itself is absolutely useless.  

Apps appear to be working  - YouTube, Netflix, Amazon.  

Anyone have this problem, or know of a resolution?

Thanks
