Has anyone had their main Port 2 die on them? Any good tests I can do that I might have not done to try and figure out what is going on?
UPDATE: Reading some more forum posts and user reviews online and it seems Port 2 is known to go bad! Ugh! I have had the projector for just over a year so my understanding is that it will still be in warranty. I'll make an RMA call Monday morning.
I just recently got my UHD65 back from Optima for a port 2 failure. I do think the cause was due to a static discharge since my AVR went out at the same time.
In my case, the limited information on the repair RMA indicated they changed out the internal scaler. The firmware was also updated.
I immediately noticed a marked improvement in the picture quality in both HDR and cinema modes. Particularly flesh tones. I no longer have to turn off dynamic black to do away with the weird face posterization. On the other hand, when fed twelve-bit 4k, the banding is much worse than before, but setting my UB900 to 10-bit clears that up almost entirely. Now I need to find a streaming device that I can set to 10-bit HDR since it appears I cannot with my ROKU Ultra.
In short, while sending it in for repair is a pain, I think you'll be glad it was necessary in the end.
There is a port 2 reset procedure you can try too. In fact, the Optima tech wanted me to do this before I sent it in until I told him I had already tried it.

BTW, you might want to record your lamp hours as it will come back zeroed out.
