The HDMI died on my OCB. I tried multiple factory resets. Unplugged for a day. Tried various devices directly to HDMI 1, 2, 3, 4. None work. I noticed the STB warning was briefly appearing after starting up over the past couple months but would disappear before I could even click to reset connections.
Other odd behavior, I can still search for HDMI devices for AnyNet and it finds them, AVR, Dish Hopper etc. And in Menu settings I cannot turn on/off UHD HDMI setting or change Audio HDMI type. Both trigger same message "Unable to turn on/off UHD, unplug HDMI cable and try again". Even when no HDMI plugged in, or when plugged in to any port.
Other than not being able to get an HDMI connection (always no signal or STB prompt), the TV and SmartHub works fine.
I've ordered a used OCB from Ebay for $114. Will see if that works. TV less than 3 years old, nothing moved or changed recently. We did have minor power outages or brief brownout/power surges a few months back. Maybe that is the source of failure but TV is plugged into fairly decent surge protection. Even my touchy Denon X7200WA hasn't complained recently.
So underwhelmed with anything Samsung I've owned in recent years. If the replacement OCB works I'll likely demote the TV to kids playroom and get me one of those fancy LG C7s as the prices plummet with the C8 going on sale this month.
JS9000 worked pretty ok most of the time. But some glitches, never used SmartHub again after getting Fire TV that was so much better. And the whole pain in the butt with purchase/download Vidity 4K content on quirky disks that never resulted in much decent content. Hardware failing in less than three years... come on... What a lame customer experience Samsung. Never again.
