Older iflight bumblebee
Success mini vtxv3

I can get it to work in bf or buy pushing the button
But after I turn it off it reverts to no power out
To push the button I have to take it apart I have to push button two times then I get lights and video ,to use bf I have to turn it off to hook it up
Any buddy got an ideal what's going on?

I guess it keeps going into pitmode on power up.

Do you have pitmode setup on a switch in Betaflight modes tab?

No pit mode on switch

I wish it would, resets to no power,even after setting it to 25 mw in bf
I can get it to show and go into osd control but not have it set there after reboot
I just tried cli set vtx power to 1 (25 mw) that dint hold ( yes I typed save)
Pit mode should be 25 mw

Also when I first plug in battery I get fuzzy week picture then fade to snow
Lights on vtx go solid red, flashing white light next to it until I push button 2x
Then I get a good picture
I think I got a bad vtx table from what I read,it's an older vtx
Iflight mini vtx v3
Pit/25/100/200/400/500

Can you do a quick test?

1. Disable Smart Audio in Betaflight on the Ports tab
2. Power cycle the quad
3. Set the power on the VTX
4. Power cycle the quad

Does the vtx go back into Pitmode?

I don't have smart audio I have IRC tramp
But
I'll try that!
How would you have me set up the vtx
By button or in bf?

ok so i disabled irc tramp
powered up with battery 
and i got a picture no osd
except a timer
and no setup info in bf for vtx cuz i disabled irc tramp
so ill push the button to set power

thanks for your help

So no going into pit mode now after that I'm getting a picture
I was able to change band and channel and I think power cuz I got 3 blinking red lights
I had to adjust goggles
After that I re setup irc tramp into bf
And all the setup stuff is back with power preset to 0 by default
But I can plug in a battery and get a picture!!
Oh some of my osd stuff is gone in goggles witch is weird?
But I can fly it with a picture now

I'm not sure if this matters
I'm using bf 10.8
And I'm sure the fc fw is older

And
If you had not helped I would have replaced that vtx
So again THANK You

BF 10.8 is the Configurator version.

Go into the CLI and type version to get the firmware version.

The osd elements disappearing means there was a conflict and the configurator reset the settings. You can add back osd elements in the Betaflight OSD tab.

I did go into bf and had to tick all three boxs to get that parameter back on the OSD I just checked one box for most of that stuff before
