I wouldn't be surprised if that blue lines issue is what caused the initial delay and JVC worked around it but it still is rearing its head. It's sure taken a while to get a supposed fix for this. It could be due to the fact that its so hard to reproduce though. I mean if some guy cant reproduce it more than once per 100 hours then I imagine an engineer at JVC might be dealing with a similar situation. Then to make a FW change and try to re-test. At what point do you think your fix solves it? 100 hours? 500 hours?
