Due to me not being used to the connectors on the board, I accidentally connected power supply to USB OTG port. After disconnecting and connecting on the right plug, the board won’t boot (no signal on HDMI). Power led (red) still lights up.
Thanks for your reply. Yes I am aware OTG it is not intended for that. However the board has no video signal on HDMI or RCA. Is there a guide for troubleshooting available somewhere?
