Mike - This same issue happened again tonight.
I was planing Roger Waters The Wall 1080p Blu-ray in my UB900 and it was fine. I then switched inputs on my 8802a to cable TV and instead of seeing the TV show I was greeted with these scrolling lines again, exactly like before. Both times this has happened it has involved a concert Blu-ray. As a reminder, the first time was David Gilmour and it occurred when making a chapter selection within the Blu-ray menu.
I was willing to sweep the last one under the rug and chaulk it up as a fluke. However now we have a pattern and I would like to know what can be done about it. The last time to reset it I powered off and then pulled the power cord. This time I powered off and then it was straightned out once it came back on. Just like last time I tried everything possible (switching HDMI inputs, pulling/reinserting cables, changing sources etc) but it required a power cycle to fix it.
I did call JVC about the issue after it happened the first time. The gentleman I spoke to said he never heard of it and seemed to shrug it off (it was like humm never heard of it, oh well). I said I would email him a clip so they could look into it. I sent the clip then, which was on the 24th and never heard back.
Although something in the sources may be triggering the issue, clearly JVC needs to update something so that the projector does not get stuck in this situation where it has no way to recover short of a power cycle.
Please let me know what the next steps are. Thanks.
