9XR Pro won't turn on and "buzzes"
Posted: Wed Jun 01, 2022 3:17 pm
Hi all,
I believe I may have "shorted" the output pins while attempting to flash the firmware on my X8R XJT module via the s-bus pins inside the module bay.
Turning the radio off/on no longer shows the bootloader (the screen doesn't even turn on). All I get is a weird continuous buzzing sound and that's it.
Any ideas of where to start with troubleshooting this? I'm looking for a schematic if possible.
