My C31 is not turning on by remote or front panel about 3/4 of the time in the last week or so, possibly since 05D3 came on my HR34. Sometimes a RBR on the C31 brings it back to life; sometimes it takes pulling the power plug. When it comes on everything seems fine. This is a new problem - I got the C31 mid-october and it did not have this issue until recently. It's our main viewing location so it's on for at least 6 hours a day and turned on several times a day. C31 software is x707 10/19. If it weren't for the coincidence with the HR34 software upgrade I'd assume bad hardware and call for a replacement.
