Where is Onkyo Philippines located? Searched the net and found a service center sa may West Ave., but not sure if they're third party or offical Onkyo. Plus, I want to make sure they can fix it since I have to bring the unit from Mindanao to Manila.
FYI, got it semi-working, by plugging in my Cignal box to HDMI 2 so that it's always powered, and it seemed to work; now, HDMI 3, 4 and 7 are working, but still nothing from HDMI 6 (I haven't checked others).
I guess it's good for now that I don't have that much sources, but I'll be limited to the number of HDMI-In I can use for now.
