Prior to the most recent firmware update, my BD player has been excellent and performed flawlessly. But after the most recent update there is a very annoying drop off in picture (sound contines to work) every few mins while watching a BD. I've tested 4k HDR and normal blurays and it doesn't matter. I also used the same BD discs in my BD changer BDP-CX960 and it plays flawlessly. I have the latest high speed HDMI cables from Amazon (same cables that did not have a problem prior to the update) and my TV and receiver are the latest models (less than a year old) from Vizio and Denon. Not sure what's happening but all signs point to the firmware creating this issue. 

Sony - if you're monitoring these forums, please advise that you're aware and are working on a fix. 

Thanks!
