I've been working with Sony (to no avail) on this issue. I get the occasional "no input" screen. To fix, I unplug HDMI and plug it back in again. It doesn't happen all the time, it only happens about once a week or two.
I've tried the following, without finding the cause of the problem
...using a different HDMI port...so it's not the port
...using a different HDMI cable...so it's not the cable
...resetting the tv to factory conditions and i checked to make sure the software was up to date...so it's not a software issue
...(as the only fix is to remove the HDMI and push it back in again) I tried the connection to the cable box, as well as the connection to the tv...so it's not the cable box hardware
...rebooted cable box...so it's not software
...I called Sony and they sent a repairman to swap the motherboard ...it's not the processor
The issue never arose with my previous flat panel tv, albeit it was a ten year old Westinghouse, not a modern 4K HDTV, so it's (probably) not the cable box
its not a major inconvenience, but a pain.
While the fix is somewhat easy, unplug and plugging in again, it's an annoyance.
X1 box with Sony XBR55X700D
Since I've pretty much eliminated many (all??) of the possible TV related causes, I was wondering if it could be the X1 Box?
Any thoughts?
