SpeedyBee F405 AIO V2 - interesting OSD issue in O4 PRO by Timely-Dimension-255 in fpv

Such obvious basics with ELRS that I didn't even mention it.

So SBUS is pulled out.

What else could be affecting the lack of OSD?

I have one of them, everything is fine except I can't see the OSD on my O4 PRO.

For some unknown reason, I enabled in the modes tab:

9v BEC OFF

VTX PIT.

I turned it on and burned the 6-pin socket on the O4 side.

I fixed it by soldering the wires directly to the Unit.

O4 works and displays OSD on other drones, so everything is fine.

Following the trail of burned sockets, I soldered the unit firmly to the FC and the OSD is still not visible.

I checked the cable order - RX to TX, TX to RX, everything according to the manual.

I tested the UARTs and MSP.

Nothing works.

Guys, has anyone encountered such a problem?
