Unfortunately the issue happened yet again tonight. Tho it may be fortunate in that it seems I have a way to reproduce it.
Here's what I did tonight:
- Was watching 1080p60 from Xfinity X1 box
- Switched 8802a input to Panasonic UB900
- Roger Waters The Wall started playing automatically since that's where I left off last time.
- I took note of the Panasonic and JVC Info screens, as included below. UB900 was outputting 4K/24 SDR/BT.709 YCbCr4:4:4/12 bit. JVC says it was receiving 4K(3840)24, 12 bit YUV.
- I pressed Stop on the Blu-ray from the remote. It brought up a Panasonic splash screen, still at the same resolution.
- I switched the 8802a back to the Xfinity X1 input and then I go the horizontal lines which I have notated in the other two posts, as before.
- Mike said the next time it happened to pull the HDMI cable from the pj and give it up to 10 minutes.
- I pulled the HDMI and the screen went black. Then after about 5-10 seconds it went haywire with all sorts of flashing colors. See new video here: http://i177.photobucket.com/albums/w...ps72zcpkg1.mp4
- I left the HDMI unplugged for 15 minutes and it continued to flash like that the whole time. I then gave up since Mike said to give it up to 10 minutes.
- I plugged the HDMI back in. After a few seconds the original horizontal scrolling lines came back.
- I then had to power cycle the unit.
- The UB900 and JVC both have the very latest firmware (u83.2).
- The UB900 is connected to the 8802a using a 6 foot 4K certified Fusion4K cable.
- The 8802a is connected to an HD Fury Integral, set to EDIT custom #10
("4k60-420 12-bit BT.2020 FS") - this is the setting that strips HDR - over a 6 foot Fusion4K HDMI cable. Could the Integral be causing an issue?
I know MANY RS500 owners use this without any issues...? EDIT: YES - THE INTEGRAL COULD BE PLAYING A PART
- See note at the bottom of this post.
- And the Integral is connected to the RS500 over a 50' Celerity Fiber HDMI cable. I am not sure what is condition is triggering this, but whatever it is there should at least be a way for the JVC to be able to resync / reset its video signal.
Although I'd certainly expect the JVC to not have this happen in the first place, the problem is exasperated by the fact that it cannot recover without a power cycle. This scenario is not a fluke scenario either - it is very common for me to be watching 4k/24. I have played several 4K UHD blu-rays presumably at 4K/24 without this happening, but those were with the BT2020 (in both SDR and HDR) if that should matter. I have also watched 1080p Blu-rays in BT.709 that were not concerts without this happening. The common thing so far is that both Blu-rays this has happened on have been concerts. Not sure if that's just a coincidence. Although since The Wall is playing back at 4K/24 I'm not sure that even matters (it's not like it is a 4k60 signal).
Mike - Can you please update JVC with this latest information and let me know what other troubleshooting steps you'd like me to take, and where we go from here? Thanks.

EDIT: I turned all the gear off and removed the HD Fury Integral. I then repeated the sequence outlined above and the HDMI lockup did not occur. I went back and forth between playing The Wall and back to Comcast X1 three times and I could not trigger the lockup to occur. I cannot say for sure whether it is definitely the Integral because I don't know for sure if the sequence will always cause the lockup with the Integral in the chain. So later today I will put the Integral back in and then repeat these steps. If the lockup occurs then I will have more confidence the Integral is playing a role. In which case I wonder why others are not seeing this issue, given how popular the Integral is with JVC owners...?
