Factory built configuration is:
X8 Octo frame
APM 2.6
GPS + Ext. compass
Telemetry
OSD
Video
DX8 Tx + AR8000 Rx
Everything worked Ok initially.
Flew 7 times, no crashes, no major issues. Position Hold and loiter tested Ok, 7th landing normal, no bumps, no tough hits to the airframe. When trying to fly for 8th time: No arm. ABC led Red and Blue normal behaivour but no arming. Went back home.
Connected to MP, sensors are working Ok, no signal from Rx (tested it in Radio Calibration), so that's the reason for not arming, I started checking and noticed this:
Receiver led flashes once when connecting then turns off.
Unpluged receiver, tested it alone: same result: Fast green flash, then off.
Now I tested the board by pluging USB cable, No red ABC, 4 Blue ABC Flashes then off, green (power) led is the only led that stays on.
Can´t debug, please help.
Thanks in advance.

Can you connect via usb to the apm at all ? Have you tried removing the cover and verifying if any of the other leds come on ? i think the green your referring too has a small label on the board "im alive" and there are two others "rx and tx" which should flash if your doing stuff on the usb ?
