I went back to running everything through my receiving into the hdmi1 on the PJ. Since I made this change I have had 5 consecutive days of no lock ups. This leaves me to believe my problem is one of three issues now.
1. The second HDMI cable I was using is causing problem. I kind of doubt this since others are having issues.
2. The projector does not handle switching between HDMI 1 and 2 reliably.
3. The projector does not like the direct connection to the Oppo.
I'm going to test my current setup with the other HDMI cable to rule out number 1. Are other people having this problem using both HDMI inputs? Does anyone with this problem run an oppo directly to the PJ or another brand?
I've had a couple more exchanges with Mikel at JVC. Initial test doing direct connect of my sources to the projector all worked with the exception of one test, which was inconclusive. When doing the direct connect, I switched them out one at a time on HDMI-1 rather than plugging one into HDMI-1 and one into HDMI-2 and then switching projector inputs like JamMcD mentioned as a theory in his testing, so I am going to repeat the test. In addition, here is their latest suggestions:
Our engineers are requesting for you to try the following:
1. Use a different HDMI cable. Preferably High Speed and not longer than 30 ft (as part of troubleshooting).
2. This Pioneer SC68 seems to have 4K pass through, but does not have 4K scaling. But, Pioneer does have a firmware update for this model that is supposed to improve the stability of HDMI. We would recommend for you to contact Pioneer and make sure it has the latest firmware (Ver 1-198-084-512-125)
3. The Pioneer does also have a very wide range of video processing functions. Where ever possible, I believe it will be best if these are turned off. While these are likely not causing the lock-up, they could be adversely affecting the picture. A couple of key points: RES: We would recommend for you to set this to PURE. That seems to be the setting that would be closest to a pass through. V.ADJ: This may or may not be available. If it is, we would not use any of the presets. Instead, we would set it on “Memory” and then set every one of the individual adjustments to zero.
4. Try setting your JVC projector to Auto Color mode. We would recommend for you to have your device/source run in its native format/ standard output (Auto) method and not to have the receiver converting things. Again, any processing you can turn off on the receiver is good at this point. Once the system is running reliably you can start to turn things back on and experiment as much as you want.
I replied that I didn't think it was the cable as it works fine for days at a time and I used the same cable with my X55 for eight months, so it seems unlikely. I did request a recommendation though on an alternate 20' cable that they would recommend for troubleshooting. My receiver already has the latest firmware and has for 6 months or more. I did turn off the Pioneer SC-68's Advanced Qdeo Video Processing (including video conversion options from RGB to YUV for the PS3) and in conjunction set the projector to auto mode for the color space now that video conversion in the receiver is disabled. Again, these options were working fine on X55 without issue, so I'm quite doubtful it's an issue with related equipment. Unfortunately, nothing here seems very promising at this point. If others of you out there are still having problems please contact JVC directly and feel free to PM me so I can help pass along other experiences for the JVC engineers looking into the issue.
A little off-topic, but perhaps related to my unit: One thing I have noticed is recently is that I'm seeing no little-to-no change when e-shift 3 is engaging--even when I move the sliders A LOT and press the before/after button. On the X55, it was readily apparent with the defaults and switching through the modes. At first I just thought it was more just more subtle, but I'm really struggling to see any change at all now. Maybe if I put up the resolution pattern again... I'll have to try that tonight.
