FPV google display black screen after play a while without power on

Does i need to "power on" fpv google before quad?

It seems to be black screen from google after I play a while on my 5 inches drone without google before I plug the power to turn on the fpv google.

It just showing RSSI 99 % and battery voltage level only.

Why?

FYI, I'm using AKK FX2 Dominator under 250mHz range.

I'm ensured everything liked VTX antenna is connected and stay with Raceband 7 (6 to 8 out of WIFI interruption) and play it over green field.

Sounds like your cam didn't power up for some reason or the vid signal from cam to vtx was momentarily dead... In general I power up tx before rx for control link, so transmitter in hands on before powering up quad so it is basically immediately getting control signals but for goggles can do them before or after and shouldn't matter the goggles are receivers but the broadcast from quad for analog is open to anyone with a receiver to tune into (no binding like with the control input unless talking dji fpv gear)

Yes, You are totally right.

I'd finally found the root cause of problem. My Camera's solder of 5 volt supply point din't working

after test with voltmeter (near to my FC's Video In & Out solder point).

I managed to solder my camera's 5 volt input to other 5 volt supply point, but everything about OSD

view is gone(Of cause I'd solder my camera's Video-In to Video-Out of VTX module).

My Last 5 volt supply point (Camera's 5 volt) just leave blank, Do I need to solder an wires

extension 5 volt to my last 5 volt supply point (Camera's 5 volt) to bring back my OSD?
